The Super/DS™ is the first puffy to take a stretch fabric and weave face, back, and baffles from a single fabric. So, not only are constricting stitches and glue a thing of the past, it means more breathability and flexibility, less cold spots and down migration. With the Super/DS™ Hybrid Vest, climbers warming up at the boulders before the sunrise and dirtbags at the Red River Gorge in the fall will never have to sacrifice movement for warmth again.
