Therm-a-Rest NeoAir UberLite — 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 NeoAir UberLite is the lightest inflatable pad Therm-a-Rest makes, using a triangular core matrix for stability and an R-value of 2.3 for three-season comfort. At 250 grams it's roughly half the weight of most competitors, and it packs down to the size of a water bottle.
Who Is the Therm-a-Rest NeoAir UberLite Best For?
Weight-obsessed three-season bikepackers who want the lightest full-length pad available. If that describes your riding style, the NeoAir UberLite 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 250g and $190, the NeoAir UberLite is the lightest option in this category. 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 $76 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
What We Like
- +Absurdly light at 250g for a full-length pad
- +Packs to the size of a small water bottle
- +Triangular core matrix provides good stability
- +Quiet fabric — no crinkly space blanket sound
Watch Out For
- −R-value of 2.3 limits cold-weather use
- −Thin material is more puncture-prone than thicker pads
- −Requires a pump sack or patience — breath inflation adds moisture
The Bottom Line
We haven't scored the Therm-a-Rest NeoAir UberLite, 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: 250g, $190, 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
Therm-a-Rest publishes a packed size of 3 x 7 in, which is 0.8 litres as a stuff sack. Of the 55 bags we track that publish a capacity, 52 have room for it and 3 do not.
Volume is computed from Therm-a-Rest'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 250g the NeoAir UberLite is the lightest in the category we track, against a category median of 465g.
At $190 it undercuts 11 of 19 of them, against a median of $235. That works out at $76 per 100g — above 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.
