Exkin® Platinum
This is a very lightweight non-woven fabric that has a thin metalized layer applied to the surface. Exkin® Platinum thermal technology reflects radiant heat back to the user. Unlike reflective films used in conventional sleeping pads, Exkin® Platinum is silent.

Thanks for your question. In an air mat (regardless of brand), the reflective layer reflects radiant heat equally well regardless of which way up a mat is facing – so there is no ‘warmer’ or ‘cooler’ side.
When the ground is cold, the reflective layer (in a Sea to Summit mat, this is a silent material called Exkin Platinum) will significantly reduce heat loss into the ground. When the ground is warmer, there is less or no heat loss into the ground; but the sleeper will not perceive this as being warmer.
If you have questions on this, email us at info@seatosummit.com

Is this reflective in both directions? I.e. can you turn it over to avoid the reflectance when you are camping somewhere warm and only want the comfort?
