Description
Our trekking-enthusiastic designers have ecodesigned this compact sleeping mat to insulate you from the ground and ensure a good night's sleep when bivouacking. 2.5 cm thick! Principle of a self-inflating mat. A self-inflating mat is made up of a waterproof coating bonded to an open-cell foam through which air circulates. When you unfold the mat, it regains its shape and thickness (2.5 cm for the MT100 mat) and fills with air. However, you will need to finish inflating it by mouth until you reach a comfortable pressure. The self-inflation is more or less noticeable depending on the thickness of the mat. Ease of assembly and disassembly When using it for the first time, unroll the mattress with the valve open for 24 hours on a flat surface, then inflate it and leave it for another 24 hours with the valve closed, under pressure. You can then pack it away again. When bivouacking, take out and unroll the mattress as soon as you pitch camp, with the valve open, to make pre-inflation easier. A self-inflating mattress only inflates by itself to about 60-70%. The rest of the inflation is completed by mouth, until a comfortable pressure is reached. What is the R-value? The R-value measures thermal resistance. It measures the ability of a mattress/mat to retain heat or prevent it from escaping from a warm body (the human body) towards a cold ground. The higher the R-value, the better the insulation of the mattress/mat. It is important to know that R-values are additive. This means you can use 2 mattresses/mats to add their R-values together. All our mattresses/mats are tested according to the ASTM F3340-18 standard. Which R-value for which use? R-value from 0 to 1.9: exclusive use in the hot season (summer) R-value from 2 to 3: use in 2 or 3 seasons (spring-summer-autumn) R-value from 3 to 4: use in all 4 seasons R-value of 4.5 and above: use in all 4 seasons and in extreme conditions (glacier, polar regions and high altitude) Little tips for a good night's sleep on the mattress/mat Open the mat and adjust the pressure by pressing lightly on the IN valve (cap open). A mat that is too firm is often synonymous with discomfort. The silicone patches on the top of the mat serve to reduce slipping of the sleeping bag on the mat. How to repair a leak in the mattress/mat? An inflatable mattress/mat can be punctured... but it can also be repaired! During use, the greatest possible care must be taken during installation and handling. In case of a problem, we recommend the use of self-adhesive repair patches (code: 8557113). Self-inflating mat with double valve and non-return system. Anti-slip silicone parts to limit the sleeping bag from slipping. Valid for temperatures above 5°C. 3-year guarantee.
