Our Top Picks

Cool bags are great for keeping food chilled, whether you’re going camping, for a picnic or packing your kids’ school lunch. There’s a wide variety of cool bags and boxes out there to choose from, so, finding the right one takes a bit of research. As ever, we’re here to help.

The best cool bags should see an end to sweaty strawberries, melted chocolate, and – worst of all – warm wine. You might want a one-size-fits-all option, or you might decide you need two different cool bags or boxes for different things.

There are active and passive cool bags. Passive ones insulate food and should keep food and drink at the temperature it’s already at. These ideally need to be packed out with ice packs or ice, which helps keep things cool inside.

The fuller your cool bag, the better it works (but the heavier it becomes), and if you can freeze water bottles or juice boxes beforehand, this is great. If you prefer to use ice to chill down your cool box, look for one that’s easy to empty – a drain valve in a rigid cool box will help.

These passive cool bags and boxes are ideal for picnics, hikes and anything else where you need portable cold food and drink. But if you’re going away for longer and have access to some electricity, an active cool box may be better.

Active cool boxes plug into the mains or via a lighter in your vehicle and work as mini fridges when you’re on the go. They actively cool the air inside them – some even have fans to keep the air moving. These are certainly fancier but more expensive and bulkier to carry. To help you decide which cool bag or box is right for you, we’ve rounded up our favourites.

How we tested

Our reviewer tried and tested a range of cool bags, to bring you the best
Our reviewer tried and tested a range of cool bags, to bring you the best (Zoe Phillimore)

We’ve been testing cool bags and boxes – passive and active – for years. We’ve been camping and enjoyed almost 100 picnics, beach trips, hikes and days out with various cool bags. Through thorough testing, first and foremost, we wanted to check that each one insulated our food. Warm drinks and soggy sandwiches have no place on a picnic. We also looked at ease of use, portability, price, ease of cleaning and how stylish the cool bags look (call us shallow). Here are the ones that made the cut.

The best cool bags and ice boxes for 2024 are:

  • Best overall – Outwell Fulmar deep freeze box: £65.99, Amazon.co.uk
  • Best budget buy – Campos cool box: £22, Argos.co.uk
  • Best lightweight ice box – Coleman xtreme cooler box: £69.98, Amazon.co.uk
  • Best for small picnics – Habitat backpack cool bag and picnic set with rug: £35, Argos.co.uk
  • Best hamper gift – The Colourful Garden Company grey round cooler basket: £79, Thecolourfulgardencompany.co.uk

Outwell Fulmar deep freeze box

best cool bags and ice boxes
  • Best: Overall
  • Capacity: 30l
  • Weight: 2.8kg
  • Dimensions: 51.5cm x 36.5cm x 33cm
  • Why we love it
    • Robust
    • Great for chilling
    • Comparatively lightweight
  • Take note
    • Can’t be carried one-handed

Sturdy and robust, this passive cool box feels like it’ll last you a lifetime. The clip fastenings ensured the cool air stayed in the box for ages, keeping all our chilled goods nice and cold. We found that, because the carry handles are on the side, you cannot do a one-handed carry, which could be a bit annoying if you have lots of picnic kit to lug from the car. However, the carry handles are comfy to hold and feel durable, even when you’re carrying a full box.

At 2.8kg it’s lightweight compared with some of the other large-capacity cool boxes in this round-up. The box has been designed to enable you to carry large bottles upright, making it perfect for parties. We liked that it was wide and reasonably shallow, meaning we could see what was lurking at the bottom much more easily. A drain valve means it’s great for filling with ice and keeping it topped up, too.

Campos cool box

best cool bags and ice boxes
  • Best: Budget buy
  • Capacity : 29l
  • Weight : 2.2kg
  • Dimensions : 43cm x 39cm x 29cm
  • Why we love it
    • Cheap
    • Decent capacity
    • Can stand bottles up
    • Easy to carry
  • Take note
    • Doesn’t keep things cool for as long as other options

A budget-friendly option, this Campos cool box is ideal for picnics and days on the beach. With a capacity of 29l, it’ll fit up to 50 cans. It’s also tall enough to hold 2l bottles upright. The handle is easy to carry, thanks to a slightly wider grip in the middle that fits ergonomically into your hand. We also liked that the handle doubles as a fastening, meaning we could lock the lid shut while transporting, keeping cool air in more effectively. This doesn’t have the keep-cool might of some of the other options in this round-up, but it’s great for day trips.

Habitat backpack cool bag and picnic set with rug

Habitat cool bag review indybest
  • Best: For small picnics
  • Capacity: 20.5l
  • Weight: 1.6kg
  • Dimensions: 41cm x 30cm x 17cm
  • Why we love it
    • Great accessories included
    • Ideal for small spreads
  • Take note
    • Limited capacity
    • Can’t accommodate larger items

We were overjoyed with the extras on this cool bag – it comes with a picnic set for four and a water-resistant picnic blanket. We think this would make a great gift for a couple, as, despite there being four of everything in the picnic set, we felt there’s only really space for two people’s food and drinks. The space is also quite narrow and thin, so you have to pack it carefully and we weren’t able to just lob in massive Tupperware boxes. However, we loved it for the ease with which we could chuck it on and head out on a bike ride, taking a bottle of fizz and some crisps with us (we know how to live).

Petromax 22l cooler bag

Petromax cool bag review indybest
  • Best: Heavy-duty cool bag
  • Capacity: 22l
  • Weight: 2.5kg
  • Dimensions: 43cm x 34.5cm x 34.5cm
  • Why we love it
    • Well made
    • Easy to carry
    • Great insulation
    • Robust
  • Take note
    • Expensive

When we first opened this, we were surprised by how thick the walls are, as this bag feels fairly cool bag-like. However, it’s clearly built to be like a flexible cool box, and everything about it is robust. It kept our picnic cool and fresh throughout a leisurely meal – and it even survived a Greek salad spillage, which we were able to wipe up with no problem. We liked the water-repellent zips, with loop pulls that made it easier to open. There are also plenty of other features to make this more “adventure” and less prissy. There’s a heavy-duty shoulder strap with big carabiner clasps, four pockets on the outside and a bottle opener. It claims it keeps things cool for four to six days. Our picnics don’t last that long but it definitely feels carefully designed to ensure freshness is locked in for longer.

The Colourful Garden Company grey round cooler basket

The Colourful Garden Company cool bag review indybest
  • Best: For gifting
  • Capacity: Unspecified
  • Weight: 800g
  • Dimensions: 36cm x 36cm x 44cm
  • Why we love it
    • Great gift
    • Can be personalised
    • Great for bottles
    • Looks beautiful
  • Take note
    • Limited use
    • Bit pricey

This has wedding gift written all over it – you can even get it personalised with the initials of the happy couple. The basket is incredibly well made from willow with an antique-wash finish that makes it look timeless and smart. It’s beautiful to display year-round in your home, too. There is a zipper chiller compartment in which you could put food but we opted for a more liquid-lunch affair when testing this basket. The capacity is pretty decent, and you can stand up a good amount of bottles inside along with some ice. When carrying the basket, you can zip on the removable lid, to keep everything cool. We were thrilled with this stylish option.

Liewood Toby thermal bag

Liewood cool bag review indybest
  • Best: For kids’ packed lunches
  • Capacity: Unspecified
  • Weight: Unspecified
  • Dimensions: 13.5cm x 20cm x 15cm
  • Why we love it
    • Great for kids
    • Internal pockets
    • Carry strap
    • Well made
  • Take note
    • A bit pricey for a lunchbox

This little lunchbox is cute as a button and got our mini testers keen to take a packed lunch into school. It’s a fairly simple design, with a handle on the zip-up lid, but we liked that it comes with a shoulder strap, too, which makes it easier for kids to tote to the lunch hall and back (such tasks are arduous when you’re five, apparently). It has two elasticated compartments inside, which is handy for tucking in a mini ice pack and stowing away delicate snacks. There’s plenty of depth in there to accommodate a hearty lunch and a juice box – our old kids’ cool bag couldn’t stretch to this. The design isn’t too in your face, so, even older kids will be OK taking this bag into school.

Quechua isothermal backpack

2 Quenchua.jpg
  • Best: For hikers
  • Capacity: 20l
  • Weight: 500g
  • Dimensions: 42cm x 29cm x 19cm
  • Why we love it
    • Super lightweight
    • Inner pockets
    • Comfortable to wear
  • Take note
    • Style won’t be for everyone

This is a very comprehensive yet lightweight 20l cool bag. The isothermal feature should keep food cool for seven hours without the need for an ice pack. You’ll need to chill your food first but this is handy, as it means you don’t have to lug heavy ice packs around with you. We loved the mesh pockets inside, which meant our drinks bottles stayed upright and leak-free. There are two zipped pockets too, one of which is in the main compartment. This meant we could keep meat and non-meat items separate. Comfy padded straps, a chest strap and loops for your thumbs make this a very comfy wear, even when fully loaded. A great one for those who like an off-the-beaten-track picnic.

ProCook insulated picnic backpack

6 ProCook.jpg
  • Best: For accessories
  • Capacity: 15l
  • Weight: 1.6kg
  • Dimensions: 28cm x 30cm x 37cm
  • Why we love it
    • Sophisticated
    • Includes lots of accessories
    • Decent capacity

This cool bag has everything you need to get a classy picnic started. The front pocket includes four sets of cutlery, a bottle opener, wine glasses, four plates and a chopping board. We know what you’re thinking but it’s still pretty lightweight. The main pocket has enough room to keep a chilled picnic for four, and it did keep things pretty cold, despite not having the foil-style lining. The navy and striped design means it looks very smart, while padded straps make it fairly comfortable to carry.

Fortnum & Mason eau de nil

8 Fortnum Mason.jpg
  • Best: Premium cool bag
  • Capacity: Unspecified
  • Weight: Unspecified
  • Dimensions: 35cm x 37cm x 26cm
  • Why we love it
    • Looks premium
    • Great for brand lovers
    • Generous capacity
    • Internal pockets
  • Take note
    • Bit cumbersome to carry

In the hallmark duck-egg blue of F&M comes this very handy holdall. There’s a really good capacity in this cool bag – plenty of space for strawberries, salads, sandwiches and other picnic essentials, such as Pimms. We loved that the lining of this bag has a Fortnum & Mason print – it’s such a nice touch. On a more practical level, the two internal pockets were useful for keeping food separate, and there’s an elastic strap for holding a bottle upright. There’s also one external pocket, which isn’t insulated but comes in handy for corkscrews and that kind of thing.

Yeti roadie 24 cool box

best cool bags and ice boxes
  • Best: For passive cooling
  • Capacity: 24l
  • Weight: 5.8kg
  • Dimensions: 42.2cm x 35.6cm x 44.2cm
  • Why we love it
    • Great insulation
    • Good for standing up bottles
    • Carry strap included
    • Non-slip feet
  • Take note
    • Expensive
    • Have to buy shelf separately

We were keen to see if Yeti’s cool box lived up to the hype. These durable boxes are pricey, and we wanted to get a feel for whether they were worth the money or whether it’s just clever branding.

Folks, Yeti has put its money where its mouth is. It is the smallest of the brand’s cool boxes that kept our drinks chilled for 48 hours. It’s tall enough for a bottle of wine to stand inside, and you can buy a dry-goods shelf for it, which will keep your sandwiches and salads out of the icy depths if you choose to fill the box with ice.

It isn’t light before it’s full but we found that the carry strap made lugging it a bit easier. It is designed to be slim enough to fit in the footwell of the backseat of a car, and it has non-slip feet, so it won’t slide about in the boot or your boat. We liked that the fastenings were easy to open one-handed, and kept the freshness locked inside. It comes in an array of colours, too.

Stanley adventure hard cooler

best cool bags and ice boxes
  • Best: Large-capacity passive box
  • Capacity: 28l
  • Weight: 6.07kg
  • Dimensions: 47.1cm x 39.7cm x 54cm
  • Why we love it
    • Spacious
    • Drainage plug
    • Robust
  • Take note
    • Not comfy to carry
    • Fiddly fastenings

This is a bit of a beast for a passive box, but provided lots of cooler space for a full weekend of camping. Indeed, it can hold up to 40 cans at once, and claims to keep things cool for four days. Certainly, after a summer weekend of hot days, our drinks were still cold, if not icy.

We liked the fastenings, which locked in cold air – although, they’re tricky to get shut again. We also liked the drainage plug for getting rid of any melted ice. The carry handles are practical and durable, if not the most comfortable to use. Certainly the Stanley adventure felt built to last, and it comes with a lifetime guarantee. You’ll want to camp with your strongest friends, though, as this cool box is heavy.

Stanley adventure series 15.1l hard cooler

best cool bags and ice boxes
  • Best: For couples
  • Capactity: 15.1l
  • Weight: 301g
  • Dimensions: 42.5cm x 32.5cm x 28.5cm
  • Why we love it
    • Great for couples
    • Good for fishing trips
    • Easy to carry
    • Good insulation
  • Take note
    • Not suitable for big picnics

This cute little cool box is perfect for two, whether you’re going on romantic picnic dates, or spending the day on the beach. It has an easy-to-carry handle, which locks into place, meaning you can hook it over your arm and it won’t swing about. The Stanley 15l can hold 21 cans of beer – cocktails and soft drinks are also valid.

We found, when we filled it to the brim, it kept our drinks noticeably cool (you will have to pre-chill everything first). Another thing we liked was the bungee fastenings on top – these held our picnic wine glasses in place nicely. There’s also space to stand drinks on the lid.

Coleman 28QT xtreme cooler box

best cool bags and ice boxes
  • Best: Lightweight cool box
  • Capacity: 26l
  • Weight: 2.2kg
  • Dimensions: 47cm x 31cm x 43cm
  • Why we love it
    • Lightweight
    • Well made
    • Versatile
    • Hinged lid

Despite this cool box from Coleman being lightweight, it’s surprisingly robust. We made good use of the lid, which can double as a table, with four slots to stow drinks, and it’s been made to use as a seat, too. The hinged lid makes it easy to flip it open one-handed but it doesn’t have any fastenings, so, be sure to store it securely, to prevent spillages. The slim profile meant we could tuck it in the footwell of the back seat of our car – handy in our over-packed vehicle.

It claims to keep drinks cool for three days. While it didn’t have quite as good insulation as the Yeti (£225, Yeti.com), say, it is a relatively purse-friendly option. The Coleman xtreme feels well made, with a handle that has a grip on the underside, to make lugging it slightly easier, and that can cope with weighty items in the box.

Halfords electric cool box

best cool bags and ice boxes
  • Best: Electric cool box
  • Capacity: 40l
  • Weight: 8.4kg
  • Dimensions: 55cm x 37cm x 43.5cm
  • Why we love it
    • In-built fan
    • Good capacity
    • Dividers
    • Can be wheeled
  • Take note
    • Heavy

If you’re going away for a long period of time, whether you’re camping or driving a long distance, this cool box is going to work well for you. It’s large but it can plug into the mains or the lighter of a car (it comes with both cables), to actively cool its contents. There’s also an in-built fan to keep circulating air within the box, and a climate-control dial, so you can decide how cool you want the box to be.

Inside, there’s enough space for 56 cans, and it’s been designed so you can stand three 2l bottles up inside it. We liked that there were two removable dividers in the box, which meant we had flexible space and could keep food and drink separate. Although we wouldn’t want to make a habit of lugging this box around, it does have wheels and a pull-out handle.

Easy Camp chill cool box

best cool bags and ice boxes
  • Best: Small electric cool box
  • Capacity: 24l
  • Weight: 3.95kg
  • Dimensions: 40cm x 29cm x 43cm
  • Why we love it
    • Plenty of power adapters
    • Low-power mode
    • In-built fan
    • Dividers

Perfect for cars and campervans, this cool box can run off 12V and 230V – it comes with plugs for both, plus a European plug. It cools food to about 15C below the outside temperature and can warm to 50C if you so wish. A switch on the outside lets you choose between “eco” and “max” settings, which we appreciated when we were worried about power. Plus, there’s a fan inside to keep air circulating around your food, so things are kept just so.

We liked that there was a divide included, and two slots to slide it into, so you have flexible space. It’s worth noting the divider doesn’t cover the full depth of the cool box, so we found we had to plan a bit more, in terms of what went where. However, it did mean we could still fit in bulkier items and have the divider up. There are three cup holders in the lid, making it a great table for campervan sundowners, too.

Icey-tek cube cool box, 18l

Icey-tek cube cool box, 18l, best cool boxes
  • Best: Smaller-capacity cool box
  • Capacity: 18l
  • Weight: 5.8kg
  • Dimensions: 38cm x 38.3cm x 35.3cm
  • Why we love it
    • Easy to carry
    • Versatile
    • Compartment divider included

This compact box is one we found easy to carry, despite the almost 6kg weight. The solid carry handle stopped it whacking our shins or swinging about as we lugged it with us for a picnic. The lid doubles up as a table, with four slots to pop drinks into – handy if you’re on slightly uneven ground. You can also slot in a compartment divider, which we found useful for people with dietary requirements and for keeping drinks and food separate. There’s also the option to add dry-food shelves at the top, which prevented us from having to dive down to the bottom of the box to find our lunch – and kept our soft food from getting squished. We also liked the rubber latches, which were easy and flexible to use, and seemed to keep the food cool for a decent amount of time (all day). If you’re pondering keeping drinks cool rather than food, this box will hold up to four bottles of wine upright at once. Cheers to that.

The verdict: Cool bags and ice boxes

We highly rated the Outwell cool box. It’s well proportioned with lots of space for a large picnic, yet it is lightweight. The box feels completely life-proof in its durability, and we think it offers great value for money. If you’re off on a longer trip or want beefier cooling facilities, the Halfords cooler is brilliant. For one-handed carry, the Coleman gets our two thumbs-up approval.
