I admit I was a little skeptical after unfolding the sheet and seeing that the bottom was only a series of straps. I thought the sheet would twist or turn off in the night. Surprisingly none of us have done it yet! However, I do have one "thermarest style" pad which is mummy shaped and the sheet really doesn't stay put. So I have purchased a set of the snap buckles for this pad and use it without the sheet and snap the quilt directly to the pad. So far the glue is holding but I only have one nights test so far.

I bought the fitted sheet in conjunction with the Term-a-Rest Tech Blanket, and I have to admit, it works pretty well. The sheet has a series of connectors around the edge that hooks up to the tech blanket to make an impromptu sleeping bag (my primary warm weather setup). connecting the the fitted sheet is 3 expanding straps on the bottom with material that helps make it non-slip. I have only used it twice so far, but it has worked pretty well. my biggest gripe is that it is a bit of a chore pulling the sheet over the mattress, but you can live with the inconvenience :) A very well constructed product as well, with reinforcement around the area where the inflation knob is located on a mattress. I believe anyone getting a tech blanket should also get this product as well.

We use these sheets with a self inflating pad that is not made by Thermarest but of comparable dimensions. For our warm weather camping, they are great and if I'm not washing them, they roll right up with the pad. They stay put on the pads, even with wiggly grandchildren.

Works great with Prolite 4 and with the Therm-a-Rest Tech Blanket (Blanket isn't very warm though). Although it is a nice convenience to have it is definitely not necessary for a good nights sleep. Luckily it rolls up with my pad or else I probably wouldn't bother. Worth it if you have the extra money.

I ordered 2 of these hoping they would add some friction so our sleeping bags wouldn't slide down on the trail pro pads. However, the material is even more slippery than the thermarest itself. It is also an extra item to carry around, so I returned them!
