Take on blustery runs from a cocoon of warmth. There's many impressive details, starting with a built-in turtleneck that pulls up into a secure hood and breathable face mask. Thumbholes and watch windows keep you warm without fuss. Finish with a water-resistant exterior and fleecy interior for the most comfortable protection. We love it for: cold weather running and rain • 77% polyester & 23% spandex • Quick n' Fit hood: 89% polyester & 11% spandex • CLO (thermal insulation): 0.23 rating • PFC-free durable water repellent finish (environmentally-friendly!) • Soft, fleecy interior • Semi-relaxed fit • Laser-cut perforations in mask • Watch window on top of wrists • Hand wash cold & air dry to preserve reflectivity, The rabbit Cocoon 2.0 keeps us quite cozy as an outer layer with just a short sleeve base layer in temperatures in the 20s to 30s F, even with some wind, and as a mid-layer for temps down to -5F. The PFC-free, water-resistant, smooth-faced finish resists light snow, and the 77% polyester/23% spandex body breathes really well — even as we work up some heat on the hills. Sweat is wicked away speedily and dries in a flash, so in the coldest climate, it's a perfect cold weather option. No flaws or stains s or holes or fading Size Md Chest 19 Length from shoulder 23.5
