Volven Ultralight Self-inflating mat - Black

Single-person self-inflating mat made from 75D polyester, known for its high durability and resistance to abrasions and mechanical damage. The lightweight and resilient polyurethane foam along with excellent thermal insulation at R-Value 2.9 provides efficient protection against cold and uneven ground.

The model stands out with an insulation coefficient of R-Value 2.9, determined according to the ASTM F3340-18 standard. This parameter defines the degree of insulation from the ground—the higher the value, the better the heat loss limitation.

Interpretation of R-Value used in the outdoor industry:

• 1.0-2.0 - designed for summer conditions (night temperatures above approximately 10 deg. C),
• 2.1-3.5 - spring, summer, and fall use (around 0-10 deg. C),
• 3.6-5.0 - in cold conditions, around 0 deg. C and negative temperatures down to about -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 sleep system (sleeping bag, clothes), type of ground, and individual user's resistance to cold.

The mat, with a thickness of 3.8 cm, ensures high comfort and effective insulation from uneven and cold ground. The outer layer of honeycomb polyester material is characterized by good resistance to abrasions and damage. Inside, there is a self-expanding PU foam that automatically draws in air when the valve is unscrewed, giving the mat the appropriate resilience. The risk of air escaping spontaneously is minimized by a patented valve design.

Transport is facilitated by a compression strap with Velcro and a cover. The set also includes a repair kit for minor repairs.

When rolled up, the mat reaches compact dimensions of 29 x 14 cm, making it easy to fit into a backpack.
