Volven Ultralight XL self-inflating mat - Black

One-person self-inflating mat with a length of 193 cm, made from 75D polyester fabric, which is highly resistant to abrasions and mechanical damage. The use of lightweight and resilient polyurethane foam, as well as excellent insulation with an R-Value of 2.9, guarantees effective protection against cold and ground irregularities.

The model features an insulation coefficient of R-Value 2.9, compliant with the ASTM F3340-18 standard. This parameter determines the level of thermal protection from the ground – the higher the value, the better the protection against heat loss.

R-Value interpretation used in the outdoor industry:

• 1.0-2.0 - use in summer conditions (night temperatures above approx. 10 deg. C),
• 2.1-3.5 - spring-autumn application (approx. 0-10 deg. C),
• 3.6-5.0 - cool conditions, around 0 deg. C and negative temperatures to approx. -5/-10 deg. C,
• 5.1-7.0 - winter use, temperatures below 0 deg. C,
• above 7.0 - winter conditions with increased insulation requirements.

Actual thermal comfort depends on the sleeping system (sleeping bag, clothing), the type of ground, and the user's individual sensitivity to cold.

The mat with a thickness of 3.8 cm provides high comfort and robust insulation from uneven and cold surfaces. The outer Honeycomb polyester material is characterised by good resistance to abrasions and mechanical damage. The interior contains self-expanding PU foam which, upon opening the valve, automatically draws in air, giving the mat the appropriate springiness. The risk of spontaneous air loss is reduced by a patented valve design.

Easy transport is ensured by the compression strap with Velcro and a cover. Additionally, the set includes a repair kit for minor repairs.

When rolled up, the mat takes on compact dimensions of 35 x 17 cm, making it easy to place in a backpack.
