The Outdoor Vitals Ultralight Sleeping Pad is an insulated air mat with an R-value of 4 (measured to the brand's own legacy standard rather than the newer ASTM F3340 protocol, worth keeping in mind when comparing across brands) and 8.9 cm of loft — enough cushioning for side sleepers who need pressure-point relief on rock and roots. In the regular size (183 × 51 cm) it weighs 510 g and packs down to roughly 20 × 8 cm.
Horizontal baffles and a 20D ripstop polyester shell on both faces keep the construction simple and reasonably durable for a fabric this light. A pump sack doubles as the stuff sack, which saves pack space and avoids condensation from lung-inflating the pad directly. Expect a moderate amount of crinkle noise typical of lightweight air pads — a minor trade-off most ultralight sleepers accept for the weight savings.
With an R-value-to-weight ratio around 7.8, this pad suits 3-season backpacking and shoulder-season trips where warmth-to-weight matters more than maximum durability or a silent night's sleep.
