The Alpkit Numo is a no-frills inflatable sleeping mat designed for ultralight backpackers, bikepackers, and minimalist campers who prioritise weight and packability over luxury. With a stripped-back design, compact dimensions, and a price tag that undercuts most competitors, the Numo has earned a reputation as one of the most accessible and efficient sleeping mats for non-car-based camping. While it doesn’t offer insulation or plush comfort, it delivers surprising performance for its weight class.
Design and Build Quality
The Numo is constructed from PU-coated 33D ripstop nylon, a lightweight yet durable material that resists abrasion and punctures. The mat features longitudinal air chambers that run the length of the pad, rather than the more common horizontal baffles. This design helps reduce weight and bulk while offering a modest degree of body contouring.
Once inflated, the mat measures 180 cm in length, 49 cm at its widest point, tapering to 43 cm at the foot, with a thickness of 7–8.5 cm depending on inflation level. The mat weighs approximately 468 grams, making it one of the lightest full-length inflatable mats on the market2.
The valve is a simple twist-lock design located at the head of the mat. While functional, its placement can make it slightly awkward to fully deflate the mat, especially when trying to roll out the last pockets of air.
Inflation and Packability
The Numo is not self-inflating, meaning users must blow it up manually. Fortunately, inflation is quick and easy—taking less than a minute for most users. Despite its generous thickness, the mat inflates efficiently and holds air well throughout the night.
When deflated and packed, the Numo compresses down to a remarkably small size, easily fitting into a side pocket or dry bag. This makes it ideal for ultralight setups where every gram and cubic inch counts.
Comfort and Sleep Experience
While the Numo lacks insulation, its 8.5 cm thickness provides excellent cushioning from the ground. The vertical baffles include slightly oversized outer chambers, which help keep the sleeper centred and reduce the likelihood of rolling off the mat during the night.
Despite its narrow profile, many users report surprisingly good sleep quality, even in cold conditions. One reviewer noted a comfortable night on frosty ground, attributing it to the mat’s thickness and chamber design. However, side sleepers may find the mat less supportive, with hips potentially sinking between the baffles3.
The Numo is best suited for back sleepers and those who don’t toss and turn excessively. For colder conditions, pairing it with a closed-cell foam pad or using it inside a bivvy bag can help mitigate heat loss.
Insulation and Temperature Rating
The Numo does not include any insulation, and Alpkit does not provide an official R-value. This means it’s not ideal for winter camping or alpine conditions without additional insulation. For three-season use, especially in temperate climates, the mat performs adequately when paired with a quality sleeping bag.
Some users report using the Numo in bothies or summer bivvies with success, though it’s generally recommended to add a foam layer underneath in colder environments2.
Durability and Longevity
Despite its ultralight build, the Numo holds up well under regular use. The ripstop nylon shell feels robust, and the valve mechanism is simple but effective. Users have reported years of use without significant wear, though care should be taken to avoid sharp objects and rough ground.
The mat’s lack of internal insulation or complex components means fewer points of failure, which contributes to its reliability. However, heavier users (above 100 kg) may want to test the mat’s support before committing, as Alpkit does not specify a maximum weight rating.
