As sales of fleece-lined jeans skyrocket, these are the styles to buy now

With sales of Acai Outdoorwear's thermal fleece-lined jeans skyrocketing after Boris Johnson's lockdown announcement, the styles have been going in and out of stock at lightning speed. With the brand claiming that the fabric is both breathable and shower resistant, we think these are the ultimate skinny-fit trousers to be wearing this season. While not something you'll see on the catwalk, we'll certainly be donning these on our next socially distanced stroll. We predict another sell-out, so you'll want to act fast.

Italian hosiery brand Calzedonia impressed us with its offering of fleece-lined jeans that are not only functional, but fashionable. The brand claims that the brushed fabric on the inside gives these leggings both an extra-soft and comfortable fit, and we're here for the elasticated waistband, which will make you feel like you're still in your pjs. Warmth and comfort? Sounds like a win-win to us.

Certified B-Corp and one of our all-time favourite sustainable outdoor brands, Finisterre has designed the perfect trouser for those looking for a more relaxed fit. Having paired its traditional organic cotton denim with a recycled polyester fleece lining, these jeans promise to be comfortable and warm. With a mid-rise fit, the brand claims the stretch denim makes them easy to put on and take off.

Thanks to the stretch in these jeans, the brand claims that they'll sculpt to your body. They're designed to be high waisted, and if you're looking to switch things up from your classic black skinny, they are also available in indigo, grey and blue. We'd wear them with this Asos Design ultimate cotton T-shirt (£6, Asos) loosely tucked in, which took the top spot in our guide to the best white T-shirts.

Mimicking the look of skinny jeans, yet offering all the best features you'd expect from outdoor gear, these trousers are quick-drying and shower resistant. Thicker than the brand's lightweight collection, but less insulating than its classic thermal skinnies, these are the perfect middle ground. If your size is out of stock, sign up for email notifications to stay in the know on when they'll be back. A winter wardrobe essential.

With a "thermal effect inner", we like that the look of these high-waisted skinny jeans hasn't been compromised for practicality. With a zip and button fastening as well as real pockets at the back, we'll be adding them to our basket straight away. They're also available in black, should you prefer.

While not exactly jeans, leather trousers are everywhere, making these bottoms the perfect way to tap into the trend while keeping comfortable and warm. Featuring a soft, fleecy interior, these not only look the part, they are practical too. We'd wear them with an oversized cream roll-neck jumper (£15, H&M) and a pair of white Veja trainers (£115, Net-A-Porter).
