Key Features

• 650FP Water-Repellent Duck Down   – Filled with 650FP down that resists moisture and maintains loft even after 120+ minutes of soaking. With 90% down content and 1000mm+ cleanliness rating, it delivers odor-free, long-lasting warmth. RDS-certified for humane and fully traceable sourcing from farm to finish.

• Dual-Zipper Multi-Mode System   – Features side-open, full-open, and foot-vent modes, allowing you to free your arms, stretch your legs, or open it completely as a blanket. Sleep in any position without feeling confined. (*Foot-vent and full-open modes not available on BASE1100 model.)

• Square Baffle Construction   – Vertical baffles divide the down into independent square compartments, preventing fill from shifting or clumping. This ensures consistent, even insulation across the entire sleeping bag with no cold spots.

• 20D Ultra-Light Fabric   – Crafted from lightweight 20D fabric that is water-repellent, breathable, and tear-resistant. It offers reliable protection against light moisture and outdoor wear while keeping the bag featherlight and easy to pack.
