Inflatable insulating mattress designed by our passionate trekking designers to sleep comfortably while trekking or bivouacking in cold weather.Thanks to its R-Value of 3.3, this mattress is perfectly suited for 3-season use. Its weight is still low (670g). And its pouch also turns into a pump bag!

Volume and folded size

Folded dimensions Ø 12 cm x 30 cm.Volume: 3,4 litres.

How to inflate your mattress

To prevent moisture from being blown into the mattress, we recommend that you use the pump bag in the pouch.
To do this, unroll the entire pump bag/pouch. Connect the valve of the pump bag to the “IN” valve of your mattress. Blow to about 10-20cm from the inlet of the pump bag, to inflate the main volume as much as possible. Roll the bag on itself to the valve to push the air out of the main bag into your mattress.

What is the R-Value?

The R-Value is a measure of the thermal insulation. It measures the ability of a mattress to retain or prevent heat from escaping from a warm body (human body) to a cold floor.
The higher the R-Value, the better the insulation of the mattress.
Please note that the R-Values can be added; this means that you can use two mattresses and add their R-Values.

All our mattresses are tested to standard ASTM F3340-18.

What R-Value for what use?

R-value from 0 to 1.9: Hot season (summer) only
R-value from 2 to 3: 2 or 3-season (spring-summer-autumn)
R-value from 3 to 4: 4-season
R-value of 4.5 and higher: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)

Tips for sleeping well on your mattress

Once you are lying down, remember to adjust the inflation pressure of the mattress by slightly pressing the IN valve (open cap). A mattress that is too hard is often synonymous with discomfort.

Silicone patches on the top of the mattress are designed to reduce the sliding of your sleeping bag on the mattress.

ADDITIONAL SUSTAINABLE DEVELOPMENT INFORMATION

Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this impact on the environment, we use only mass pigmentation on one yarn out of every two for the grey fabric on the back of the mattress, thus reducing our consumption and our impact on water.
In addition, 70% of the wadding used as insulation is recycled polyester.
These actions allow us to reduce CO2 emissions by 12%.

How to repair a leaky mattress

An inflatable mattress is not puncture-proof but it can be repaired!
When using it, take every care when installing and handling it.
In the event of a problem, we recommend using self-adhesive repair patches (ref: 8584596).
