1:1 Descente-style UPF 145+ sun-protection skin jacket in 95% nylon / 5% spandex — featherweight, quick-dry, splash-resistant, with hood and adjustable cuffs. Unisex.
Built for summer outdoor use, this 1:1 rep Descente-inspired sun-protection jacket delivers certified UPF 145+ ultraviolet shielding in a shell so light it feels like a second skin. The 95% nylon / 5% spandex fabric blocks over 99% of UV radiation, wicks sweat instantly, dries in minutes, and resists light rain — making it the one jacket you can pack into a palm-sized bundle and forget about until you need it. The one-piece hood provides 3 cm of additional neck and scalp coverage, adjustable cuffs seal out sun at the wrist, and zippered side pockets keep essentials accessible. Available in almond, mint green, earth yellow, and black. Unisex sizing shown on chart in listing images.
