Polartec Alpha Insulation
Polartec Alpha Insulation, a recycled synthetic fill that is remarkably warm for it’s weight and density. Polartec Alpha Direct has an incredibly high rate of moisture vapor transfer due to it’s highly open structure and lack of backer fabric, and when combined with our highly vapor permeable shell fabric this is the most breathable winter vest we’ve created.
Breathability
To emphasize the focus on high-intensity breathability, we’ve perforated the under-arm area of the side panels for even more rapid moisture transfer. This breathability, combined with the incredible warmth to weight ratio of Polartec Alpha Direct make a fantastically warm package.
Plenty of Storage
Three large pockets for all-day ride storage and a hidden security pocket with glove-compatible zipper puller.
Ventilation
Two-way, YKK Vislon zipper provides smooth, durable action and allows for ventilation from both the bottom and top, also allowing easy access to jersey pocket contents.
