Bestway - Ridgelite Ultra-Light Insulated Cold Weather Sleeping Pad - Large

Ridgelite is 198 cm in the XL version, with a R-4,9 ASTM rating

ASTM 7,6 is rated for -30 celcius. Do you really need that in Britain? I get the price difference. Its nothing. But the Ridgelite is more than enough unless you go camping in extreme winter conditions - its 198x63 for the same price as Alpinelite 183x53, and 100g lighter. Anyway. If you need that kind of insulation, it would be downright idiotic not to bring a backup, foam etc underneath. I've had 3 inflatables fail on me. Its not a question *if*, but *when*. And its always during the night and a micro leak impossible to locate. Nothing draws heat from your body, than the ground. So - bring a foam backup. Even at +20 you could risk hypothermia sleeping directly on the ground. Bonus: that IXPE pad makes my R4,9 into a R6,7

I agree. I have the Ridgelite XL (same pad, but an R-value of 4,9) - must say Im blown away! Costs about the same as a trip to McD, is ASTM rated, comfy for a 100+ kg guy and makes absolutely no noise compared to a chips bag (aka therm-a-rest). This and my Flextail Pillow has got to be the most insane, stupid cheap, comfortable items I have bought!
