I am attempting to use pieces of windsheild reflector as a Z-liner. Seems to offer pretty good insulation (although the nights aren't cold anymore to really test it), but the pads don't stay in place very well.
How do the Z-liners attach to stay in place in the pockets? The Clark website talks about velcro but the only velcro I see is at the top of each pocket to hold the pocket opening shut. Is this the only attachment for the pad or do newer models have velcro inside the pockets as well?
