Sleeping Pad Closed-Cell Confirmation

[4GNomad]

I picked up three of those blue Ozark Sleeping Pads at Wally World to cut into strips to insulate the ribs, then tape. I just want to confirm that these are closed cell. The description says they are Polyolefin, which I read is non-porous. Does this mean it is closed-cell? It also does state that its 100% waterproof and moisture resistant. Wasn't sure if this was just the coating over the pad, or if the pad is truely closed cell.

that should work. it's not Ensolite but it is closed cell foam. I just found this out "Gold's Gym Yoga Mats" are Ensolite. highdesertranger
