works well with fabric barrier [SEP] I personally would recommend getting a larger size cooling pad. The bigger, the better in this case. It can be expensive though. I like it's ability to stay cool even in the high temps but don't put it directly on your skin. The plastic it's cased in does not breathe so you need to put it under your pillow or sheet (whatever). I put mine under my sheet and quickly learned not to sit on it during the day because you at first think you sat down on something wet but realize it's just that the pad is cool. enjoy!
