The Nemo Tensor 20 Short is an ultra lightweight and compact airbed that provides comfort and stability for a restful night's sleep. 

Nemo says:

Tensor features NEMO'S lightest weight fabrics and cutting edge insulation. Constructed with low stretch fabric baffles to eliminate elasticity, Tensor's height, stability, quiet fabrics, paltry weight and pack size make it the ultimate in ultralight pad design.

The minimal weight and pack size of the Tensor 20S Airbed is ideal for light and fast backpacking. It packs down smaller than a classic Nalgene water bottle and at 238 grams it's only an extra 31 grams heavier than the Short Thermarest NeoAir Xlite but nearly £25 cheaper. This un-insulated tensor does still have the heat-reflective layer, so is warmer than typical air-only pads. This causes a slight crinkle noise but it's much, much quieter than the NeoAir mats.

Nemo have not given their mats R Value's but they do say that the comfort temperature range of the un-insulated Tensor mats are about -1 to 4C  and the insulated versions are about -9 to -4C, which would put the insulated versions right about the same warmth as the Neoair mats. Overall this short mummy shape keeps the weight to a minimum and the 7.5cm thickness and Thermal mirror makes it warmer than traditional air-only mats.

Comfy little airmat for summer use.

I usually am a tossing and turning side sleeper. With this airbed, i move less during my sleep and wake up fully rested compared to my full length allseason mattress.

I am 175cm (~ 5'8") tall with 56cm (~ 22") shoulder width and the size of the Nemo is perfect for me. When falling asleep on my back, i am on the Nemo from head to +/- half lower legs (and the other half is on my pack) and when sleeping in foetal position i fully am resting on it.

The low-stretch baffles (it does work, no side collapsing!!!) and the thickness are a improvement compared to my neoair.

I like it so much that i consider purchasing a full length insulated Tensor for winter use.

Good service and fast shipping from Thanks!
