Thermarest NeoAir Uberlite L Sleeping Mat

Product Information

If you’re thinking of using your sleeping pad in relatively colder weathers than, in that case, XLite would be the better option for you. The XTherm, as its name suggests, is the warmest of the three NeoAir sleeping pads. Its R-value of 7.3 stands up to even extreme winter adventures with overnight lows below 0 degrees F, especially if you layer a closed-cell foam pad beneath it. It’s not strictly necessary for those chilly shoulder-season nights that hover around freezing, but it wouldn’t hurt. This matt has an R-Value of 2.3 which in real terms means that this matt is best suited to warmer weather trips and adventures.R-Values are an international standard of insulation and (in simple terms) indicate the materials ability to reduce heat flow through conduction, radiation or convection. Therefore, the higher the R-Value, the lower the heat transfer and the greater the insulation properties of the material.

Warmth / season is the biggest functional difference between these three pads. Sleeping pad warmth is designated by the R-value, a measure of how well the pad prevents your body’s heat from transferring to the colder ground. Therm-a-Rest's lightest airbed. From alpinists to thru-hikers, those who need the lightest gear have a new standard for ultralight comfort with this superlight pad. Thermarest saysThe UberLite is the newest addition to the NeoAir lineup, and the lightest. There isn’t another pad in existence that can match its blend of featherlight weight, tiny size, decent comfort, and 3-season-ish warmth. The only real downside, in my experience, is the UberLite’s difficulty with reliably holding air. Hopefully Therm-a-Rest improves this in future versions, because this pad is otherwise excellent. Standard width for most sleeping pads. Not enough room to splay elbows, but weight is the key here. It also tapers due to the mummy shape. What’s the correlation between air temperature and sleeping pad R-values? When do you need a pad with a higher R-value? This table is based on Exped’s recommendations in Fahrenheit and Celsius degrees. Air Temperature (F): In line with current health and safety guidelines, we reserve the right to refuse any items that are (for whatever reason) not returned to us in a clean and hygienic condition. All of the NeoAir pads use horizontal baffles. We’ve found horizontal baffles are more comfortable than vertical. More on sleeping pad baffle types in our Guide.

A high price for the “lightest pad on the market”. You’re paying for name brand and utterly ultralight design. NeoAir UberLite: Ultralight option for fast-and-light types who adventure mostly in summer and occasional shoulder season conditions. Get the UberLite if you rarely see temps below 40 degrees F and are willing to treat your pad very carefully (and probably patch some punctures) in exchange for the lightest and smallest inflatable pad on the market.Therm-a-Rest has one of the best sleeping pad warranties in the business. If parts of this fail, get in touch. You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat. Therm-a-Rest also offers the NeoAir UberLite in a Large, which has a 25-inch width and 77-inch length, weighing in at 12 ounces. This is a larger, more comfy pad, but weighs significantly more. Tip: If you need to patch your UberLite sleeping pad — and you probably will — I find GearAid Tenacious Tape stays on better than the included patch kit. I’ve had to patch my UberLite twice in six nights of use. Lesson learned, spread weight out evenly and carefully!

Thermarest’s proprietary construction provides the critical warmth needed for your lightweight adventure.In a hurry? This section sums up my recommendations on choosing between the XLite vs. XTherm vs. UberLite. I’ll go into more detail on each down below. Incredibly thin fabric. So far tests have not popped it, but it’s much thinner than other common fabric Deniers in ultralight pads. More on sleeping pad materials and Denier in our Guide. This is unfortunately where I have some negative things to say about the UberLite. Where the XLite uses stronger 30D fabric top and bottom, the UberLite uses 15D fabric, which seems not quite up to the challenge. Weight: All these pads are really light for their warmth, but making a sleeping pad warmer makes it heavier, all else being equal. Thus the warm XTherm is the heaviest and bulkiest of the three. The ultralight UberLite is the smallest and lightest, but also the least warm. The XLite strikes an excellent balance between the other two. Featherweight: Weighing just north of half a pound, the UberLite sets a new standard for ultralight comfort.

Punctures: In six nights of using my UberLite pad, I punctured it twice! Both times I was sitting cross-legged inside my bivy (which acts as a ground cloth) on what I thought was relatively smooth ground. Apparently sitting put too much pressure on a small area of the pad. Now I know better and am careful to only lie down with my weight spread evenly. It’s typical for ultralight gear to require careful treatment, but this pad requires VERY careful treatment and you should expect that punctures are likely. The Therm-a-Rest NeoAir UberLite is for those who want to be the fastest, the lightest, and don’t mind being the coldest to accomplish their goals. Where to Buy Therm-a-Rest NeoAir UberLite The UberLite has an R-value of 2.0. Anecdotally and quantitatively, it’s not as warm as the XLite, which is rated to 3.2, or 60 percent warmer. Its optimal temperature range feels close to the Insulated AXL, for which the R-value is not publicly known.If you have spent a night on the XLite or the warmer XTherm, the UberLite will feel very familiar. All of them: The Therm-a-Rest NeoAir UberLite is the lightest weight inflatable pad on the market. A bold statement, to be sure. Ready for those ultralight, ultra-fast adventures you’ve spent all winter dreaming of, this pad excels in hot environments, and hot environments only. With its compact design and feather-like weight, Uberlite is great, but as you might guess there are some trade-offs here, it’s not the most durable air sleeping pad on the market, it’s made of low denier (15D Nylon) fabric therefore if you decide to go with the Uberlite you need to be extra careful.
