The Nemo Disco Men’s 15 Regular Endless Promise is a three-season mummy-style down sleeping bag built for campers and backpackers who want reliable warmth without taking up too much space in their pack.
The snug mummy profile minimizes dead air space to hold in your body heat, while the full down insulation offers a high warmth-to-bulk ratio and compresses back into its stuff sack for easy carrying. Its regular length gives a close fit without extra fabric, so you stay cozy and can move more freely inside the bag.
Down insulation uses soft clusters that trap warm air next to your body, creating loft for heat retention. These natural fibers also rebound quickly after compression, making it simple to pack the bag away and keep your gear organized on the trail.
