Wowool Alpha Direct 90 Jacket
The jacket is made from 100% Alpha Direct 90 material, representing the pinnacle of active insulation. Its open fiber structure efficiently moves moisture away from the skin and dries quickly, while trapping just the right amount of warmth both in motion and at rest. Alpha Direct delivers an exceptional warmth-to-weight ratio that clearly stands apart from traditional fleece garments.
Beyond warmth and low weight, Alpha Direct offers outstanding breathability, making it an extremely versatile fabric for hiking apparel. The Wowool jacket works as a standalone layer while moving, as a midlayer under a shell in colder conditions, and as an added warmth layer in camp or even inside a sleeping bag.
The full-length zipper adds further adjustability: open it quickly during climbs, zip up during breaks, and fine-tune ventilation as needed. This makes the jacket a truly dynamic part of your layering system rather than just a passive midlayer. For added functionality, the jacket features large pockets that double as hand warmers and storage for small essentials.
