Besides providing comfort, sleeping mats perform a vital function
by insulating you from the cold ground to slow convective heat loss. Find which best suits the majority of your trips.
Foam-filled mats are self-inflating – drawing air in as the mat regains its unrolled shape – but may require a few puffs at the end to reach the desired firmness. Synthetic and down-filled mats will come with a pump sack to ensure moisture from your breath doesn’t get inside. The easiest way to use these is to hold the pump sack 30cm from your face and blow into it, then force the air into the mattress. Air-filled models only need your lungs to inflate.
High-density open-cell foam, down or synthetic-insulation are the warmest mattresses. Air-filled mats are the coolest, but also the lightest. Antimicrobial treatments will prevent fungal and bacterial growth inside the mat, caused by moist breath (from inflating the mattress). Foam-filled sleeping mats are die-cut or horizontally cored to reduce their weight.
Fabrics and finishes
Fabrics are patterned and coated to provide grip so the user doesn’t slide off during the night. They are DWR-coated to provide water-resistance.
Controls airflow in and out of the mat. Some mattresses have two valves; one used to inflate and the other to deflate.
Generally speaking, the thicker a mattress, the warmer it will be.
Shape and size
Most mats come in short, regular (or medium) and large sizes. They can be tapered to save weight, bulk and to make laying two mats side-by-side easier. Shorter, tapered models are perfect for summer camping. Winter models are full-length and likely to be insulated or have a reflective interior coating that slows heat loss. Prices vary depending on size.
Store the mat in a cool, dry place, unrolled, with the valve open.
A sleeping mat’s R-value (Resistance-value) measures its effectiveness at resisting heat loss. The higher the R-value, the warmer a mattress will be. The international ASTM F3340-18 standard ensures mattresses are tested in the same way to achieve consistent R-values across brands. It makes it easier for consumers to properly compare and judge the warmth of various mattresses.
Here’s a basic guide to give you an idea of what to expect from each R-value:
- R1-R2: For summer use when day and nighttime temperatures are warm.
- R2-R4: Suitable for three-season use, including conditions where you might get a mild ground frost.
- R4-R6: All season use, including conditions where you might get a heavy ground frost.
- R6+: Below freezing air temperatures day and night with cold to frozen ground.
