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.
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 is R-value? 

R-value from 0 to 1.9: Hot season (summer) 
R-value from 2 to 3: Use over 3 seasons (spring/summer/fall)
R-value from 3 to 6: Use over 4 seasons
R-value > 6: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)

What R-value do you need?

We use the same fabric on both sides of this mattress: 40 Denier polyamide with thicker 45 denier thread to reduce the risk of a tear spreading.

What component do we use on this 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 10–20 cm (4–8”) from the pump bag inlet to inflate the main bag as much as possible. Roll the bag on itself up to the valve to push the air out of the main bag into your mattress

How to inflate your MT 900 Air insulating mattress

Inflatable mats are not puncture-proof, but they can be repaired if punctured.
Take care when inflating and moving the mat. 
In the event of a problem, we recommend self-adhesive repair patches (ref. number: 8557113).

How to repair a leak on your MT 900 Air insulating mattress

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

A special coating on both sides of the mattress prevents your sleeping bag from slipping on the mattress and the mattress from slipping on the groundsheet.

How to sleep well on your MT 900 Air insulating mattress

This model is available in L and XL sizes. 
The difference between the two sizes is the length (183 cm/72” for the L; 195 cm/77” for size XL) and width (54 cm/21” for size L; 63 cm/25” for the XL).
Consider your height to choose the mattress that best suits you. 
However, also consider how much space you like to have around your shoulders. 
So, even if you are 1.75 m (5’9”) tall, you may prefer the XL size!
