Layer up and get out there. This Adi365 running vest extends your comfort range in cool weather. CLIMAWARM traps heat and releases sweat for a warm, dry and focused performance. It resists wind and rain to keep you comfortable in mixed weather, and 360-degree reflectivity increases low-light visibility. Zip pockets at the sides and chest secure keys and other essentials, while stash pockets on the back offer quick access to gels or an ultralight layer. Insulating materials trap warmth for optimal body temperature. Beat the elements with thermal insulation and water repellency for optimal shell-layer protection.
