Fascinating. Is this foam significantly TOUGHER than the polyurethane foam? I just got the polyurethane ones and it is already falling apart because I cut it quite snug to the GK1 and the snug fit tears the foam after a few removals. If it is, I would have gotten this type of foam.@Ultralight I’m looking for something like this polyethylene foam. I’m not sirenif this is best though. I have to read through some older threads.
