A cool autumn morning loop with changing weather calls for a layer that goes on and off easily, and the Explore Insulated Gilet is an insulated vest that works as an outer layer or a mid-layer. It stuffs into its zippered rear pocket when the sun comes out, and it doubles as a pillow at the end of the day. What Our Gearhead(R) Experts Are Saying:"On gravel rides that started cold and turned damp, the insulation kept my core warm and breathed on the climbs. I rode the whole loop in the same vest."
