This unisex top has become a real favourite for keeping the cold out over recent months.
Made from a Tactel (nylon) and Lycra mix, it's warm without being overpowering so it'll be effective under a lightweight outer layer for spring and early summer use too.
The inner face is fairly open compared to the outside, encouraging the movement of moisture away from your body, and it dries out fast if you do get sweaty on the climbs.
Stretchy in all directions, it offers a body-hugging fit that makes the most of the fabric's technical properties, with thumbholes to keep the sleeves in place and a close turtleneck.
Flat-stitched throughout, with raglan shoulders, it's fantastically comfortable.
