What do you think about this product?



Too small, but well made.

This cover is made well, strong seams, high quality and appears as if it would last a long time. Unfortunately it is too small for the pad it is sized for. I purchased the XXL which is sized for the Mondo King 3D according to Therm-a-Rest, but it is too small. The cover is set to the largest cinch and loosest buckle length in the back, and still barely manages to get onto the mattress. The top is too narrow to reach both seams on the pad, and it is too short as well. This causes the pad to warp downward as it tries to pop out of the cover. I do not think the cover is usable on the pad with the tension it creates.

Great upgrade to increase versatility

I've used it several times

I purchased this sheet in size regular to use in conjunction with my X lite pad, and an ultralight backpacking quilt for 3 season use. The sheet is easy to remove for cleaning and eliminates the sticky feeling from any skin contact on the X lite. The pad also fits any rectangular pads of the same width, so it is versatile too. Great addition to my pad.

I was wondering if this might fit a Nemo Tensor 20R, because if so, that'd be dope. thanks. Jason.
