Vests for the best. The Shelter Hybrid Padded MTB vest for men is our lightweight insulation vest with PrimaLoft® Silver Insulation padding. PrimaLoft Silver brings 100% recycled material made of bottle chips reprocessed and spun into fibers finer and softer than cashmere, delivering uncompromised loft and warmth. The sustainable C0 DWR water-repellent finish allows flexibility, regardless of what conditions the weather has in store. Lightweight in nature, the Bike & Ride Panel Concept with additional 4-way stretch fabric side inserts gives you a bike-specific fit and freedom of movement in all directions. The two front zippered pockets give you additional space to store your snack bars or bike essentials with the Clear Optics Lens to keep your vision clear.
