What is the UltraLight Insulated Mat?

The UltraLight Insulated Mat is designed to offer exceptional comfort and warmth without the weight to match. Weighing just 480g and packing down to around the same size as a 500ml water bottle, you'll barely notice it in your pack.

What is it made of?

Insulation: Starting from the inside, Sea to Summit insulate the mat with Thermolite. Thermolite is a synthetic material which prevents convective heat loss between your body and the ground, boosting your overall warmth. Sea to Summit take this insulation one step further, placing an antimicrobial treatment inside the insulation to extend its lifespan. Layered above this is an Exkin Platinum fabric which reflects radiant heat loss back to you.

Fabric: Surrounding all this clever tech is a 30/40D nylon fabric which protects the insulation and repels light moisture on humid nights.

What are the features?

Unlike your typical mat which features a flat or ridged surface, the UltraLight features Loop Baffle Air Sprung Cell technology. Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with their Air Sprung Cell dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall.

In addition you also get a good quality stuff sack for compact transportation, a repair kit containing six patches for repairs while you're out and about and lastly a spare silicone valve flap.

What is the R-value?

This matt has an R-Value of 3.1 which in real terms means that this matt makes a great 3-season adventure buddy and will keep you toasty for most of the year.R-Values are an international standard of insulation and (in simple terms) indicate the materials ability to reduce heat flow through conduction, radiation or convection. Therefore the higher the R-Value, the lower the heat transfer and the greater the insulation properties of the material.
