AULP Numix Men's Midlayer Jacket Black 2026

The AULP Numix is a well-proportioned midlayer fleece that sits between base layers and your waterproof shell. It's made from two fabrics working together: a durable striped polyester mesh on the front, back and sleeves, with stretch jersey panels on the sides. This split design gives you protection where you need it while keeping movement free when you bend or reach. The fabric breathes steadily to wick moisture during active days, and it's light enough that adding it to your pack costs almost nothing.

The jacket wears close without binding. The high collar seals out wind, and full front zip means you can vent quickly if you warm up or layer it over a base layer fast. Hand pockets with zips keep your fingers warm on the go. It's finished with an embroidered AULP badge on the sleeve and a metal chest badge—small marks of a brand built in Switzerland that cares about detail.

Why we rate it

The two-fabric construction works. You get structured protection on your core and sleeves while the side panels move with you. It's a fleece that doesn't feel restrictive, and the weight means it packs small and travels well. Wear it on its own on cool days, or layer it under your ski jacket for serious cold. The polyester dries fast if it gets damp from sweat or sudden snow.

Breathe-ability is steady, not spectacular—this is a midlayer that prioritises warmth and durability over maximum airflow. That's the right choice if you're layering properly. The finish is clean, with proper zipped pockets that don't flap and a collar that actually seals.

Who it's for

Anyone layering for cool-weather hiking, urban outdoor days, or ski holidays where the temperature wobbles above freezing. It works for men of any ability and any fit—the regular cut suits most shapes. Wear it as your insulation layer under a waterproof shell, or on its own when the air is crisp but calm.
