I'm selling this as I haven't had a chance to wear it, only trying it on. This is a next-generation base layer born from the development of new outdoor materials. The ultra-thin nylon material with sweat-wicking and diffusion functions combines lightness and durability, while achieving the high breathability essential for a summer base layer. It significantly reduces stuffiness inside the garment and helps to suppress excessive body temperature rise caused by intense exercise. ■ Thin and Lightweight ■ Sweat-wicking and Diffusion ■ High Breathability Yamatomichi Atelier Blue Bottle RawLow Mountain Works HYPERLITE MOUNTAIN GEAR Zpacks Mountain Laurel Designs Moonlightgear GREAT COSSY MOUNTAIN Zimmer Built Hikers Depot palante cayl Gossamer Gear houdini and wander MINIMALIGHT jindaiji mountain mountain works Hillbilly Pot wonder peaks blooper backpacks RIDGE MOUNTAIN GEAR Gender...Men's Features...UL/Ultralight
