Volven Ultralight XL self-inflating mat - Black

A self-inflating mat for one person with a length of 193 cm, made of 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, ensures effective protection against cold and uneven ground.

The model features an insulation coefficient of R-Value 2.9, in accordance with the standard ASTM F3340-18. This parameter defines the degree of thermal protection from the ground—the higher the value, the better the protection against heat loss.

Interpretation of R-Value in the outdoor industry:

• 1.0-2.0 - summer conditions (night temperatures roughly above 10 deg. C),
• 2.1-3.5 - spring-autumn use (approximately 0-10 deg. C),
• 3.6-5.0 - cold conditions, around 0 deg. C and negative temperatures up to approximately -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), type of ground, and individual sensitivity to cold.

The mat with a thickness of 3.8 cm ensures high comfort and solid insulation from uneven and cold ground. The external Honeycomb polyester material is characterized by good resistance to abrasions and mechanical damage. The interior contains self-expanding PU foam, which automatically draws in air upon valve opening, giving the mat the appropriate resilience. The risk of air escaping is reduced by a patented valve design.

Easy transport is provided by a 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 easier to place in a backpack.
