Constructed as a single layer of medium resolution cells, our Ultra Light range gives you the lightest and smallest packed size mat without compromising on our Air Sprung Cell comfort.

When we set out to design a mat that was better than what was already available, we ultimately went back to why we carry a sleeping mat into the wild in the first place - to give us a better night's sleep.

Happy sleeping!
