Single-person green travel mattress designed to ensure comfortable rest during field activities. Ideal for extended outdoor expeditions, campsites, kayaking journeys, or long-distance bike adventures.
The model features a R-Value 4.7 thermal insulation rating, specified in accordance with the ASTM F3340-18 standard. This parameter defines the level of insulation from the ground - the higher the value, the more effective the reduction of heat loss.
R-Value interpretation used in the outdoor industry:
- 1.0-2.0 - use in summer conditions (nighttime temperatures above approx. 10 deg. C),
- 2.1-3.5 - spring-summer-fall use (approx. 0-10 deg. C),
- 3.6-5.0 - cool conditions, around 0 deg. C and sub-zero temperatures down 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 sleep system (sleeping bag, clothing), the type of ground, and the user's individual resistance to cold.
Air chambers that contour to the body's shape deliver optimal support and comfort throughout use, efficiently absorbing unevenness from the ground. Thanks to the rectangular design, users can rest in a natural and ergonomic sleeping position. Constructed from durable 20D nylon with a Rip-Stop weave for enhanced tear resistance. A protective TPU coating guards the surface against moisture and prevents water absorption by the material.
An internal layer of aluminum foil within the mattress efficiently retains heat and enhances insulation performance. The mat serves as an effective barrier, preventing ground cold from reaching the user, thereby increasing comfort and shielding the body against cooling. A wide valve ensures straightforward mattress inflation, while also allowing air to be added or released to modify firmness to individual requirements. Included in the set is a cover that makes everyday storage and transport of the mattress more convenient.
