Our Super Puffs are perfected season after season to achieve the best in form, fill and function. It’s what makes Super so super. Engineered to deliver warmth to -40°C / -40°F, The SuperSnug Puff™ Long is an hourglass puffer with a slim fit that hugs your body. It’s filled with 100% responsibly sourced, 700+ fill-power premium down that provides ultra-warm, lightweight insulation. It’s constructed with Satin Flex™ — water repellent stretch fabric with a pearlescent sheen and a soft, silky feel. This fabric is sourced from a Japanese mill that specializes in performance fabrics.
