The opinion of Aventure Nordique

Thermarest's Trail Lite is a self-inflating mattress offering an optimal ratio between weight, comfort, insulation and durability. This model corresponds to the needs of backpackers and hikers who wish to sleep comfortably on a solid mattress (75 denier polyester). The trail Lite is an insulated model with an R-Value of 3.4 with the new ASTM F3340-18 standard.

The women's model (WR in 168 cm) is warmer, which is suitable for those who are more sensitive to the cold, the R-Value is 4.5. The semi-rectangular cut of the Trail Lite increases the sleeping surface at the torso and head level and helps to bring two mattresses closer together.

Trail Lite is equipped with the latest Thermarest valve. The WingLock valve allows for faster inflation and deflation. It has a non-return valve that prevents air from escaping during inflation.
