Therm-a-Rest Synergy Sheet for Camping Mattresses

Bought this for my Thermarest XL Base Camp pad and it fits perfectly. Sheet is comfortable and should do a nice job of protecting the pad which is the main reason I bought it.

I use this on my DreamTime thermarest which has a fleece top. I sleep warm so I don't wrap up in a sleeping bag but rather use it completely unzipped like a quilt. That leaves me lying on the thermarest fleece & it's hot. I don't like that. Just used this sheet on a long camping trip with weather ranging from a bit too warm for comfort (& muggy) to below freezing and it really helped me sleep more comfortably. More like sleeping on sheets at home. Goes on easily & comes off easily. I didn't find I needed to clip the strap underneath. It stayed on the mat just fine via the four corner loops.

Very nice so far . Fits very well in MondoKing mattress from ThermRest. I do believe is too expensive unnecessarily. I have not washed it yet. It is thin , it seems strong, and it is poor insulating. Over all if you have some estra money ir ok. Again I think it is very expensive. ALSO BE AWARE of the right sizes for your mattress, for some reason taht sadly don’t remember I had ti return the first one, but i am pretty sure initially I did check very well in amazon for the right size according to my mattress, but it was inaccurate, still when you receive the sheet it comes with a “ size chart” , so I knew what exactly the company recommends acordong your mattress. Again when buying from amazon it was not as accurate. anyways try it , if not is free to return it and get the exact one after it.

Difference between ordinary and extraordinary sleep is that little extra (weight). Fantastic.

I love having my sheet on my sleep pad especially since I use a ugq quilt

XL Synergy sheet fits my 25 x 77 x 4 in NeoAir Topo Luxe perfectly

I love there Thermarest sleep system. I use a Dream Time mattress with this sheet and a Thermarest down quilt. Better than my bed at home. My own version of Glamping. Only minus is the price. However, they dry very quickly and last a long time.

I bought the large size because it was labeled to be for for 25x77" sleeping pads but it doesn't actually fit the MondoKing. If you forced it, I guess it could work (the sheet has a little bit of stretch) but the pad wouldn't be able to fully inflate. The strap that goes around the bottom of the pad isn't long enough to actually wrap around the MondoKing.This sheet looks to be for pads maybe 2-3" thick at most. I don't have a 2-3" mattress to test this with to confirm...For reference: the sheet is about 23x75" un-stretched. The MondoKing fully inflated is closer to 26x78".

I kept slipping from my sleeping pad. Not anymore with this cover!

Far too expensive for what it is. Yes its the usual quality you would expect from Thermarest but you're paying for the name I guess because the sheet (made in china) probably cost no more than a couple of quid to make. If you're just after an undersheet then look elsewhere. I bought it as a part of a sleep system. The mattress and the quilt are absolutely great but I felt ripped off with this at the price.
