Foam folding mat with an aluminum layer that reflects body heat and thus significantly increases thermal comfort. It is made of durable IXPE foam so the mat has a very long life. Tearing or punctures do not affect sleeping comfort in any way. Thanks to its shape, it fits together perfectly, it is lightweight and resistant to moisture, so you can easily carry it attached to a backpack. You can also use it partially or completely folded as a seat or as a mat with a pillow.
