Volven Ultralight Plus Self-Inflating Mat. 5904013000413. The Volven Ultralight Plus mat will significantly improve the quality of your camping experience and the comfort of your stay. This three-season Volven self-inflating mat is a development of the basic and very popular Ultralight model. This mat is a few centimeters wider than the Ultralight, has side panels, and weighs only three grams more. This version of the Volven mat has a refined shape. Anatomical profiling makes the mat narrower in the foot and head areas. Functional edges run along the side edges of the mat. On one side, they act as a kind of stop, making it harder for the body to slide off the mat during sleep, while on the other, the edges insulate from the cold and prevent cold air from entering this area. The Volven Ultralight Plus mat is made of lightweight, perforated foam, covered on the outside with durable polyester. After unfolding, the mat can be gently inflated. The mat is equipped with a valve designed to minimize the risk of air loss. The practical Ultralight Plus camping mat is one of the simplest ways to significantly increase camping comfort. The mat insulates very well from the ground. This model has been tested according to the rigorous ASTM F3340-18 standard and achieved an R-Value of 2.9. This makes it suitable for overnight stays from early spring to late autumn.
