Hands up if you’d enjoy winter a lot more if the whole biting-winds-plus-arctic-temps-and-a-sprinkle-of-sleet thing weren’t actually a thing. Us too. But given our [gestures broadly] situation, the great outdoors – and all the inclement weather that it forces upon us – is bound to play host to more leisure activities than usual this winter.

Our cold-combatting solution? UNIQLO’s HEATTECH, the thermal innovation that’s woven into the brand’s much-coveted collection of head-to-toe designs. The technology works like this: A blend of four unique fibres helps to wick moisture from the skin and then converts those vapours into kinetic energy while micro air pockets lock in the welcome heat. The resulting base layer is one that’s warm, light on the body and more comfortable than your coziest sweater. The best part is that HEATTECH is always getting better: Since creating it more than 15 years ago, UNIQLO has used customer feedback to make updates and advancements every year to ensure it remains the most insulated (and did we mention affordable?) option out there.

Those who know, know. The Japanese retailer’s iconic innerwear has hooked outdoor enthusiasts and fashion insiders alike. For many, HEATTECH is the secret to a truly simplified winter wardrobe, one that has style and function in equal measure. It means saying buh-bye to bulky layers that – let’s face it – make a mess of your intended look. Slip on a HEATTECH turtleneck and a puffer for a distanced friend hike – no extra flannels necessary. And a pair of HEATTECH jeans – designed with a high rise and extra stretch where it counts – is ideal for evening bonfires or a weekend spent on the slopes.

Now, in partnership with Uniqlo U creative director Christophe Lemaire—a Parisian design marvel revered by in-the-know fashion peeps—the brand has reimagined the classic HEATTECH long-sleeve tee with a sophisticated spin. Expect an ultra-wearable, contemporary silhouette – think clean lines and a simplified neckline – plus a range of pigment-perfect colours. (We’ve got our eyes on the muted marigold.)
