Nemo Disco 15 Review
Need a sleeping bag with more room to move, especially if you sleep on your side? In this Nemo Disco 15 review, we’ll explore why this spoon-shaped bag is a favorite among comfort-focused backpackers who don’t want to feel restricted at night.
The Nemo Disco 15 is a 3-season sleeping bag rated for 15°F and designed with a unique spoon shape that adds extra space at the elbows and knees—perfect for side sleepers. It uses 650-fill responsibly sourced down with a PFC-free hydrophobic treatment, helping it retain loft and warmth even in damp conditions.
Weighing 2 lbs 11 oz (regular), the Nemo Disco 15 is heavier and bulkier than ultralight alternatives but makes up for it with generous comfort features. These include Thermo Gills for venting heat, an integrated pillow pocket, and a waterproof/breathable footbox to keep your feet dry.

Comparisons
Nemo Disco 15 vs Therm-a-Rest Parsec 20
The Therm-a-Rest Parsec 20 is lighter, more compressible, and geared toward backpackers prioritizing performance and pack weight. The Nemo Disco 15, however, is roomier and includes unique features like Thermo Gills and a pillow pocket, making it far more comfortable—especially for side sleepers. If comfort and sleep quality are top priorities, the Disco wins. For fast-paced or ultralight trips, the Parsec is more efficient.
Nemo Disco 15 vs Big Agnes Torchlight UL 20
The Big Agnes Torchlight UL 20 is lighter and offers adjustable side zippers that expand the bag’s width. While it doesn’t have Thermo Gills or a pillow pocket, it provides good warmth and a more tailored ultralight design. The Nemo Disco 15 is heavier but better suited for recreational backpackers who want comfort features without needing to trim every ounce. Choose the Torchlight for lightweight versatility and the Disco for comfort-first adventures.
