The Nemo Disco 15 sleeping bag is a three-season bag built for backpackers and campers who move around at night and want room to do it comfortably. Rated to 15 degrees Fahrenheit, it uses Nemo's signature spoon-shaped design, which is wider at the elbows and knees than a traditional mummy bag, giving side and stomach sleepers the freedom to shift positions without feeling constricted. The spoon shape maintains thermal efficiency where it matters most while cutting excess material in areas that don't need insulation, striking a balance between warmth and pack size that appeals to hikers who don't want to sacrifice comfort for weight savings. Insulation comes from 650-fill power water-resistant down, treated to resist moisture and retain loft even in damp conditions, a critical feature for anyone camping in unpredictable weather or humid environments. The bag also incorporates Nemo's Thermo Gill vents near the chest, zippered panels that let sleepers dump excess heat without fully unzipping the bag, which is especially useful during shoulder-season trips when temperatures swing between chilly nights and warmer early mornings. The exterior fabric is a durable, breathable nylon that holds up to regular use in the backcountry, while the interior lining feels soft against the skin without adding unnecessary bulk. Practical details round out the design, including an integrated blanket fold at the top that can be secured with snaps to keep drafts out, and a contoured hood with a cinch cord for added warmth on colder nights. The bag also features a full-length, snag-free zipper with a design that allows two same-model bags to be zipped together for couples who want to share body heat and space. Compression sacks are included for packing down the bag efficiently, making it a solid choice for backpackers, car campers, and anyone seeking a versatile sleeping bag that adapts to changing conditions on multi-day trips into the wilderness.
Customer reviews
I've struggled with mummy bags for years feeling too constricted. The Disco 15's spoon shape finally lets me sleep on my side comfortably while camping in the Rockies.
Kept me warm down to freezing temps on a fall trip. Only downside is it takes up more space in my pack than my old bag.
The Thermo Gills are a game changer. I can vent heat without fully unzipping and losing all my warmth. Perfect for variable mountain weather.
This bag is incredibly comfortable and the fabric feels premium. Wish it was a bit cheaper, but you get what you pay for in quality.
