Nemo's Tensor Trail is an extremely lightweight rectangular sleeping mat for weight-conscious adventurers who still want a comfy sleep. The interior baffle design gives stable support without the wobbly waterbed feeling some air mattresses give you. Inside each baffle is a suspended layer of ultra-thin metallized film which reflects body heat. Because it is floating it doesn't make that crinkly noise when you move around, unlike some other mats.

The mat is made with 20D (top) and 40D (bottom) nylon for durability, and a repair kit is included. Also included is a pump sack which provides fast inflation and attaches easily to the pad's zero-profile, microadjustable valve.
