Basalt Alpine Half Zip Top

The Basalt Alpine half zip is a technical midlayer from OEX built around a 250gsm microgrid fabric — 95% polyester with 5% elastane for stretch. The grid structure traps warmth while staying light, and flatlock stitching keeps seams comfortable under a pack. A half zip vents heat on the climb, thumb loops with elastic binding hold sleeves in place beneath a shell, and the zipped chest pocket keeps small essentials to hand.
