Alpha® Direct 90 .v1 Pullover Jacket
All-new Alpha Direct 90 — updated fit
The sleeves have been refined to allow greater freedom of movement, making dynamic use more natural and unrestricted.
Using size L as reference:
- Upper arm width increased by 2 cm
- Forearm width increased by 1.5 cm
- Underarm space increased by 1 cm
This improves the tightness previously felt when bending or raising the arms.

A highly breathable and lightweight active insulation, designed as the core midlayer.
It works best worn over a Merino wool base layer and under a wind shell.
Naturally regulates body temperature between movement and rest.
Whether in a mountain hut, at camp, or inside a sleeping bag, it maintains stable warmth.
