Cyclos, we had to lighten up!…

Cyclos, we had to lighten up! So choice of a 3/4 mattress, very small, inflating and deflating easily. We have part of our legs and feet on the ground but the rest of the body is well insulated and comfortable. Mission accomplished for a 3/4

compact and lightweight, it…

compact and light, it suits me well for a roaming bike ride.

In size S, smaller, lighter Do not inflate it too much for more comfort, if it is too inflated, it is hard on the hips A storage bag/pump would be a plus

Very good.

very comfortable, light and easy to use.

icon-circle-checkmark verified purchase

Used in bikepacking, I took the small format to have a product. more compact, I recommend.

Bad quality

I used this mattress for 5 days of bivouac. Besides that it is very uncomfortable (but it is announced), on the 4th day I slept on the ground because it deflated afterwards. I regret having believed that it would last for life beyond 4 days!

Unfortunately, even though I am short, the dimensions and comfort are low. to carefully evaluate whether to take this model or the longer one

Very convenient

Very good, compact and light transport. Quite comfortable for an inflatable mattress.

perfect for a hammock

very comfortable, perfectly insulates the shoulders and kidneys, and in these parts, despite the lining, I was always a bit cold. I am very satisfied with the purchase. cold and windy nights are no longer scary.

Great mattress for a great price

An experienced hiker gave me the tip to try a short mattress, and I like it very much

an excellent compromise

I was hesitant about getting a short size mattress and I don't regret it at all. Not having a mattress under your legs is not bothersome at all, it remains comfortable and this makes it an ultra light and compact mattress for transporting it. I now take it on all my bivouac hikes.

Price-performance fits!

Advantage: small pack size and weight, easy to handle, good insulation when inflated tightly! Disadvantage: rather poor sleeping comfort, the feeling of rolling off the mat when changing sides, the mat shifts very quickly while you sleep. Conclusion: good compromise solution for 2-3 day tours

excellent product

used 2 months on compostelle and RAS

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) onlyR-value from 2 to 3: 2 or 3-season (spring-summer-autumn)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 the environmental impact of this model, we chose to use a dyeing process called Inchbi-ton Inch which involves dyeing one out of every two yarns. This dyed yarn is also made from a bulk dyeing process which incorporates the colour pigments from the yarn manufacturing phase onwards.This process reduces the CO2 emissions of this product.

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: 8557113).For more information, copy the following link into your browser:

Product testing

All our mattresses are subjected to mechanical tests to assess their performance and durability and ensure you enjoy a good night's sleep and an excellent recovery. We also carry out numerous field tests in real-life conditions.

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.
