Exped Sim Ultra 3.8 M Self-inflating Mat - Lichen

``````Green self-inflating mat constructed from recycled 20D polyester, renowned for its abrasion resistance. The fabric is treated with a TPU laminate (thermoplastic polyurethane). Insulation rated at R-Value 3.7 ensures effective protection from cold and uneven surfaces.

The model features a thermal insulation coefficient of R-Value 3,7, determined in accordance with ASTM F3340-18. This parameter defines the level of insulation from the ground - the higher the value, the more effective the reduction of heat loss.

Interpretation of R-Value used in the outdoor industry:

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

Actual thermal comfort depends on the sleep system (sleeping bag, clothing), ground type and the user’s individual resistance to cold.

The filling is composed of a lightweight PU foam with a density of 13 kg/m3, providing the mat with an R-Value of 3.7, ensuring thermal comfort down to -10 deg. C. Equipped with a flat valve, it allows for rapid inflation and deflation.
