Nemo Disco Men’s Ultralight Down Sleeping Bag 30°F Endless Promise

Explore unparalleled comfort on your backpacking adventures with NEMO’s Disco 30° Sleeping Bag— engineered for side sleepers who demand mobility without compromise. The Classic Spoon® silhouette expands elbow-to-knee space by 15%, letting you shift positions freely while maintaining thermal efficiency at -1°C (30°F). Our proprietary Thermo Gill™ ventilation system offers precision climate control through dual-zipper panels flanked by draft-blocking layers—no cold drafts when zipped closed or rapid heat dissipation when partially opened.

The Blanket Fold™ neck seal adapts dynamically: inflate its oversized collar for -10°C (-20°F) winter camping or flatten it completely during summer treks in humid climates. Critical areas receive enhanced protection—a waterproofed footbox resists tent condensation while maintaining breathability through body-mapped 3D baffles that prevent down clumping below the waistline.

Certified under the Responsible Down Standard (RDS), this 650 Fill Power hydrophobic down insulation maintains loft in damp conditions while using 100% recycled polyester shell/lining materials—eligible for NEMO’s Endless Promise® recycling program at end-of-life. Weighing just 950g (2lb 2oz) compressed into a 27cm diameter stuff sack yet offering room up to 183cm (6’) tall sleepers through progressive girth measurements (62” shoulders tapering to 57” hips).

Key differentiators:
– Anti-snag zipper system with reinforced slider guard
– Interlocking zipper design enables two Discos to zip together as a double bag
– PET-based shell reduces microplastic shedding by 73% compared to virgin polyester
– ISO-certified comfort (-1°C) backed by NEMO’s lifetime repair warranty

Ideal for thru-hikers needing reliable sub-freezing protection that weighs less than most lunch boxes—this isn’t just another backpacking bag; it’s your climate-adaptive sleep system built to last generations through circular manufacturing principles.
