Featuring our new proprietary thermal insulation WTV, the Seton Vest excels as a road and fast gravel layer, where its stretch woven exterior fabric helps keep out the worst of the wind, while internally, engineered loft fabric alternately retains and releases heat as you ride to keep you comfortable and temperature balanced at all times. Constructed with our signature ATP fit, Seton sports a full front zipper and spacious Anything pockets.
