For decades people have relied on the original RidgeRest mattress to provide the lightest comfort possible or to boost the warmth and durability of a three-dseason mattress for winter use. Now with our patent-pending aluminized Solar coating the RidgeRest SOLite offers a 10% boost in warmth with even more durability from surface wear and tear.
All of this with no appreciable weight gain makes it perfect for everything from extreme high-altitude climbing to entry-level backpacking.
RidgeRest & Z Lite Technology
These Therm-a-Rest innovations boost the effectiveness and comfort of traditional, flat closed-cell foam pads with heat-formed peaks and valleys. The RidgeRest uses a conventional wave pattern and the Z Lite delivers maximum compactness with a nesting waffle pattern. Both increase dead air space in the “valleys” beneath you to boost warmth, while the peaks maintain support and comfort. In addition, all but our RidgeRest Classic mattress combine these benefits with a dual-density construction that combines a denser, more durable foam on the bottom and a softer, more comfortable foam on top for lasting comfort.
RidgeRest and Z Lite Mattresses
Here we use a simple reflective surface coating of ThermaCapture to amplify the effectiveness of the heat-trapping peaks and valleys of each of these mattresses. The result is a boost in warmth by up to 15% and even greater surface durability.
Ridgerest has always been the premium choice closed cell foam mat because unlike a smooth mat it has ridges which increase its insulating properties. Now improved with a silvered surface to improve the insulation value further.
As with all closed cell foam mats it can be cut to the desired size to further reduce unnecessary weight.
|Help and advice: |
From 2020, there is a new industry standard for measuring the R-value (level of insulation) of sleeping mats – ASTM F3340-18. This new standard is the sleeping mat equivalent to the EN rating for sleeping bags.
You can now directly compare the R-value of mats rated using the ASTM F3340-18 with confidence that is a fair and accurate comparison between mats. In simple terms, the higher the R-value, the warmer the mat.
In general terms, an R-value below 2.0 is for summer use, 2.0 to 4.0 is for cooler 3 season use and 4.0+ is for winter temperatures. This will be also be dependent on your sleeping bag, how cold you sleep etc. Please contact our customer service team if you need advice on choosing the right mat for your activity.
