7.5cm Thick Air-Cell Cushioning

Want to maximise your recovery on overnight adventures? A luxurious 7.5cm thick, this Ultralight Insulated Sleeping Mat provides the perfect level of cushioning, support and stability. The secret is in our specialised air-cell technology, which disperses your body weight across the entire surface of the pad for optimal firmness, no matter what sleeping position you prefer. For quick, breath-free inflation, we recommend using our Ultralight Pump Bag (compatible with all Alton inflatable sleeping mats).

Damage-Resistant Construction

Nothing ruins a night in the wild faster than a leaky sleeping mat. Crafted from tough ripstop nylon that’s resistant to damage from punctures, abrasion, moisture and UV, our Ultralight Insulated Sleeping Mat (R4) offers extreme durability at a ridiculously low weight. Not convinced? Just watch the Gear Test, where we see exactly what it takes to puncture our Ultralight Insulated Sleeping Mat (hint: when we say ‘extreme durability’, we mean it).

Adaptable Insulation

With a R-value of 4, our Ultralight Insulated Sleeping Mat is suited to year round use in temperatures down to -1º. For additional warmth and comfort in winter conditions, we recommend pairing your Insulated Sleeping Mat with our Closed Cell Foam Pad (R2). Not sure about R-value temperature ratings? Our blog on sleeping mat R-value ratings explains everything you need to know to make an informed choice.
