Staying comfortable on the bike during the dark months is all about having an smart layering strategy. Reach for the Summit ECOLoft Vest when hitting the trail on blustery fall and spring days, or on winter rides that dont require an full jacket. This vest uses lightweight ECOLoft insulation with laser-perforated panels on the sides and back for excellent ventilation during high-output activities. Dual zippered hand pockets hold ride essentials and an PFC-free DWR coating shrugs off light precipitation and tire spray. Layer the Summit ECOLoft Vest over an thermal jersey for cool weather rides or under an shell for deep winter adventures.
