1/8″ Closed Cell Foam Pad

I would give 4.5 stars but that’s not an option.Works great but develops holes and rips without noticeable incidence during use.Used it on one trip and has several holes and rips. I don’t recall anytime that any sharp items came near it.It’s destined to become garbage within a season or two.however I used this with my 3 season inflatable mattress during a very cold 2’ Sierra storm over 2 nights and it works excellent with negligible cost and weight. When you consider the alternatives of buying a 250$ inflatable mattress versus using a z rest, it’s not a hard decision to get this.Also, it’s nice to have this on outside of your pack for lunch breaks to sit upon. You don’t need to get out a pad to inflate or anything.
