Good but few…

Good but little choice in store. Model + size

It works as expected

I slept on it 2 times. It is quite comfortable to sleep on. (Do not overblow, it must remain soft). I can't judge the insulation against the cold, it was at least 10 degrees outside. So she insulated perfectly.

Bravo for the designer…

Bravo to the designer who found the inflation system. I slept very well.

Mattress not fully satisfied

Very practical to inflate, it keeps you properly insulated from the floor, when inflated it is too narrow at the sides, you get too easily unbalanced on one side and the other

He does what is asked of him, nothing more

Positive points: - For an insulating inflatable mattress, it does not take up much space (practical in cycle tourism). - Used only this summer for the moment, you immediately feel that it insulates well and keeps you warm, without being uncomfortable. - the pump bag with the Venturi effect are great - Not ugly at all this orange! Points to improve: - the rectangular shape is a bit awkward in some 2P trekking tents when there are 2 mattresses (it overlaps the other); the sarcophagus shape (as for its non-insulating version) would have been more suitable - at the beginning, it is a bit complicated to understand how to take out the mattress and inflate it; with experience it passes - despite the sausages and patches, I still slip into my Forclaz sleeping bag :/

Very easy to transport…

Very easy to transport, to inflate. A bit limited for sleeping comfort.

good mattress

If it could be lighter it would be perfect! But honestly its weight can be understood by its characteristics, insulation from the cold and sleeping comfort, nothing to complain about.


Tried 4 times, all ok

It peaked after the 7th time I used it

It peaked the 7th time I used it, difficult to locate the pitera. And once the patch is on, it continues to lose air. I would not recommend it

I recommend, it is…

I recommend, it is really great, slept very well, thermal insulation at the top!

Integrated pump

A very ingenious pump to inflate. She surprised me that it really works, although at first glance you wouldn't believe it. You just need to have enough space around you.

Comfortable mattress

I used this mattress for 1 week of trekking. I found it comfortable, practical to put in the bag. Quickly deflates and reinflates in just a few breaths. I didn't quite understand the principle of the inflation bag and I admit that I inflated it "the old fashioned way" with my mouth on the valve itself (it's my own mattress, so I too scrupulous...). I didn't have a hole, it did its job during the week and I slept very well. To protect it, I put a foam mattress underneath. I could not test the thermal insulation since my use happened during a heat wave. Perfect, but I would like in the future why not have an integrated pillow rather than having one in addition.

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 4”-8” 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 2 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) onlyR-value from 2 to 3: 2 or 3-season (spring-summer-fall)R-value from 3 to 4: 4-seasonR-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 1 yarn out of every 2 for the gray fabric on the back of the mattress, thus reducing our consumption and our impact on water.In addition, 70% of the fill 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!In use, as much care as possible should be paid to its set-up and handling. In the case of a problem, we recommend you use adhesive repair patches (ref: 8584596).For more information, copy the following link into your search engine:

Storage instructions

In order to improve the durability and reliability of your product, store it laid out flat with the valve open in a dry place away from extreme temperatures.
