Karuishi® stretch fleece creates a smooth, resilient surface and a warm, fleecy interior for a half zip that wicks and breathes mile after grinding mile.

When pushing the pace during mountain workouts, our wicking, breathable and high-stretch half zip maintains comfort mile after grinding mile. Built with premium Karuishi® stretch fleece, the self-regulating material features integrated four-way stretch and a circular knit construction that creates both a smooth, resilient surface and a warm, fleecy interior. Integrated thumbholes keep arms down during reaching or stretching, while an inner security pocket stashes a key or a card when hitting the trail. Now with an updated fit in the sleeves for greater comfort.

Karuishi® is a technical fleece concept based on lightweight warmth and durability. A special 2-layer knitted construction creates an abrasion-resistant, anti-pilling face and a lofty, brushed next-to-skin backing. The end result is a high volume, lightweight insulator that breathes exceptionally well.
