>>2822938The sleeping pad is great. My one is 65cm wide and over 200cm long. The pump sack is too small, and it takes 22-24 inflations to fill this wide-long pad. I told this to the seller and they said the passed the feedback to their technicians. The valve not standard, however I can still inflate it with my Flextail TinyX pump using the flexible adapter, pushing it inside the lip of valve, but it needs to be topped off with the pump sack to get it to the right firmness. When properly inflated there is no crinkling. This pad looks exactly like the "Hikenture R6.0" pad, but has similar construction and baffling to a Nemo sleep mat. The vertical baffles help keep you from slipping of the mat. The two pieces of foil insulation extend the entire width, and length so no cold spots. I asked the seller for the ASTM report, which said the pad the R valve was 4.7, and I think it is accurate as it kept me warm at -1C. Total weight of 630 grams.
