AULP Numix Men's Midlayer Jacket

A technically designed midlayer from Aulp, the Haute-Savoie mountain clothing brand. The Numix delivers warmth without bulk, making it ideal as a second layer under a waterproof ski jacket. Its clever two-fabric construction—structured striped mesh on the body and arms, with stretch jersey on the sides—promotes airflow and wicks moisture to keep you dry during physical activity, while the tailored fit maintains a clean silhouette.

Why we rate it

The Numix balances performance with practicality. The combination of mesh and stretch fabrics means you get excellent freedom of movement without overheating when you're active on the mountain. Breathable construction keeps you comfortable during exertion, and the high collar adds genuine protection against wind chill. It's designed as a versatile piece: equally at home as a standalone midlayer for cool-weather hiking or buried under your jacket on the ski slope.

Who it's for

Skiers of all abilities looking for a reliable layering piece that won't add bulk. The tailored fit suits those who prefer a neat appearance under their jacket, and the stretch side panels mean it works well for anyone wanting mobility without feeling restricted.
