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 Super Puff2O™ Long is constructed with sealed seams and bonded channels to keep you dry and insulated, even in serious precipitation. It's filled with 100% responsibly sourced, 800+ fill-power premium down that provides ultra-warm, lightweight insulation. This version is constructed with Rainstop™ — waterproof and windproof ripstop fabric with a matte finish, soft feel and 2-layer construction. It’s sourced from a Japanese mill that specializes in performance fabrics.
