The Sugoi Firewall 220 Zip jacket is a sound choice for cold-weather rides.
Zip into the Firewall 220 Jacket from Sugoi, and forget about the weather. The triple-layered Firewall fabric has a flexible outer layer that moves with your body and keeps your lines clean. The layer next to your skin wicks moisture to keep you dry and comfortable, and the middle layer is a polyurethane shield that helps block wind and rain. Scotchlite accents help keep you safe on your after-dark treks.
