Weather defying technology on the exterior, cozy-soft fleece on the interior: our Gridback Fleece is made to stand out. Designed for action, but comfortable enough to kick back in after a long day casting flies or on the trail. The Gridback Fleece Vest is the latest iteration of Free Fly's technical outerwear. Lightweight, packable, and featuring a stretch woven shell to provide protection from wind and rain, this is our go-to vest to keep us warm and dry on early morning boat rides or as a midlayer when the temperature drops.
