The Uberlite is instantly recognisable as one of the Thermarest NeoAir range and you might consider it as an evolution of the Xlite mat. Although it shares heritage, the Uberlite is the latest and most extreme light weight mat in the NeoAir series and (so I’m told) the lightest air filled mat available today.
1). 64mm depth (2.5inch) is the same as the rest of the NeoAir range which has sold many thousands globally and has proven to be reliably comfortable in a range of situations and fine for getting a good night’s sleep.
2). Insanely lightweight –Regular size just 250grams. Thats 100grams lighter than the Xlite Reg, which is already lighter than most mats available.
3). The pack size is tiny. The Regular Size is just 8cm diameter by 15cm long.
Points To Note:
1). The R-Value is 2.0. It will help to keep you warm in the late Spring through to Autumn, but its not going to have enough insulation to keep you really warm on frozen ground or low temperatures in single figures.
2). The material is 15 denier! Thats half the thickness of the material on the Xlite, so as with all mats (and maybe a little more so), you’ll need to keep an eye out for thistles and brambles that could cause punctures. (A repair kit included with all NeoAir mats).
The Uberlite will appeal to everyone who’s keen to shave grams off their pack weight, but many people will still chose the three season Xlite for its R-value of 3.2 and lower price point or the four season Xtherm.
The Uberlite has been released in conjunction with the Thermarest Hyperion Hyperion 32F/0C Sleeping Bag. [Also available on the EMS website]. The two products combine to make a sleeping system suitable for temperatures down to about plus five degrees Celsius, but only weighs 710grams for both (size Reg). For those entering completions or who ‘need’ to shed the pack grams the combination is going to be hugely attractive.
