Looking for the perfect blend of low weight, comfort and warmth? The Sea to Summit Ultralight Large Insulated Mat could be everything you'd ever dreamt of!

The comfort side of things is handled by a single layer of 225 independent air sprung cells, which conform to your body shape and the terrain you are sleeping on. These air cells operate in the same way as a pocket spring mattress, so you can be sure you'll get a great nights sleep wherever you end up.

Every cell is filled with THERMOLITE® insulation, which prevents convective heat loss from your warm body to the cold ground. When combined with Exkin Platinum® - a metallised layer which reflects heat back into the mat, you end up with a mat which is a perfect companion for backpackers.

The inside of the mat features an antimicrobial treatment, protecting the mat from damage from or build-up of moisture. The inflate valve allows for easy inflation and precise fine tuning to ensure you get the perfect night's sleep, whilst the deflate valve makes packing up so much quicker. The mat is also compatible with either the Air Stream Pumpsack, or the Jet Stream Pumpsack, both available separately, for even faster inflation.
