Combining innovative design with responsibly sourced materials, it delivers a rare balance of technical performance, freedom of movement, and eco-conscious construction, ideal for everything from multi-day treks to wild camps.

The Disco is engineered to perform. Lightweight yet insulating, it packs down efficiently while offering dependable warmth across 3-4 season conditions.

Filled with 650 fill power hydrophobic down, it retains loft even in damp environments, critical for unpredictable mountain weather.

Unlike restrictive mummy bags, the Disco features Nemo’s signature Classic Spoon® shape, giving extra room at the elbows and knees so you can move naturally throughout the night. Ideal for side sleepers and those who are naturally restless sleepers looking for the best possibily of comfort in the hills. It’s the sweet spot between ultralight efficiency and real-world comfort.

Conditions can change fast, and the Disco adapts with you. Featuring a Thermo Gill™ vents that allow fine-tuned temperature regulation without exposing you to cold drafts, and a Blanket Fold™ draft collar seals in warmth or releases heat when needed. This versatility extends the usable temperature range, making it ideal for varied conditions on long trips.

The Disco has optimised insulation & warmth with a body-mapped baffle design that keeps insulation exactly where it’s needed. Vertical baffles on the torso for warmth retention, horizontal baffles below the waist to prevent down migration, and a sculpted 3D footbox add warmth and comfort where it matters most on colder nights.
