NEMO Disco 30 Sleeping Bag — Specs & Analysis
Manufacturer specifications, compared against every other sleep systems in our database. We do not test gear in the field — we measure, verify, and compare.
The Disco 30 is Nemo's spoon-shaped sleeping bag that gives side sleepers room to bend their knees without fighting the bag. The 650fp DownTek fill is water-resistant, and the Thermo Gills along the top let you regulate temperature by unzipping vents instead of opening the whole bag.
Who Is the NEMO Disco 30 Sleeping Bag Best For?
Side sleepers and comfort-first bikepackers who don't mind carrying extra weight. If that describes your riding style, the Disco 30 Sleeping Bag should be at the top of your shortlist. It sits in the Sleep Systems category alongside 19 other products we track.
How It Compares
At 900g and $250, the Disco 30 Sleeping Bag is 650g heavier than the lightest option in this category (the Therm-a-Rest NeoAir UberLite at 250g). The most budget-friendly option is the Cascade Designs Therm-a-Rest Z Lite Sol at $50.
The price-to-weight ratio comes in at $28 per 100g — a reasonable middle ground between performance and value.
What We Like
- +Spoon shape is a revelation for side sleepers
- +Thermo Gills allow temperature regulation without fully unzipping
- +Waterproof footbox protects against condensation
- +Integrated pillow pocket holds a camp pillow in place
Watch Out For
- −Nearly twice the weight of ultralight quilts
- −Bulky packed size challenges small bike bags
- −650fp fill is less compressible than 850fp+ options
The Bottom Line
We haven't scored the NEMO Disco 30 Sleeping Bag, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 900g, $250, and how both sit against every other sleep systems product we track.
The price and weight above have not yet been checked against the manufacturer's own page. We are working through the catalogue and saying so as we go, rather than letting silence imply otherwise.
Specifications and dimensions come from the sources listed above. Where a page draws on first-hand riding, it says so.
What it packs down to
NEMO publishes a packed size of 8 x 10 in, which is 8.2 litres as a stuff sack. Of the 55 bags we track that publish a capacity, 21 have room for it and 34 do not.
Volume is computed from NEMO's own packed size, treating a two-dimension figure as a stuff sack. Bag capacities are the makers' published figures, not ours — 12 of the bags we hold dimensions for publish no capacity and are left out of the count rather than assumed. A stuff sack does not reshape itself, so read the headroom as room to spare rather than a guarantee it goes in easily.
How it compares
Against the 20 sleep systems we hold published specs for.
At 900g the Disco 30 Sleeping Bag is the heaviest in the category we track, against a category median of 465g.
At $250 it undercuts 9 of 19 of them, against a median of $235. That works out at $28 per 100g — below the $51 median for sleep systems.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
