Cypress GWS Expedition

Cypress GWS – Gore Infinium™ Extra-Wide -30°F Expedition Sleeping Bag Cypress GWS redefines what an extreme cold-weather sleeping bag can be. Unlike most expedition-grade designs, this is not a mummy bag—it’s extra-wide for unmatched sleeping comfort, yet still delivers full -30°F (-34°C) protection in severe winter conditions. Perfect for polar travel, base camp life, or any expedition where warmth and room to move are both essential. With an average loft of 11 inches and an incredible 50 oz. of premium 850+ fill power goose down, the Cypress GWS completely surrounds you in a thick, luxurious barrier of warmth. The Gore Infinium™ shell provides superior water resistance, windproofing, and breathability, ensuring insulation stays dry and effective even in high-moisture, high-wind environments. Key features include: Full-length insulated draft tube plus external storm flap for maximum heat retention. Three-dimensional insulated draft collar to seal in warmth around the neck and shoulders. Secondary foot-end zipper allows the bag to open completely around the bottom for ventilation or use as a down quilt. At 4 lbs 14 oz (2,380 g), the Cypress GWS offers expedition-grade warmth with a roomy, non-restrictive fit—ideal for those who need more space without compromising on severe cold protection.
