Comfortable but heavy and bulky
I have used the Klymit Hammock V Insulated pad for two backpacking trips. The pad provides is comfortable and insulating. It is heavy, but that's the trade off you make to get the high R-value. The wings do keep my hammock spread out nicely. I use it in my Warbonnet Eldorado.
It is a challenge to pack up in the morning while keeping it in the hammock. It's akin to wrestling an octopus; one V wing pops out, so I tuck it in and another at the far end says "my turn!" I haven't figured out a system yet. The procedure so far is to deflate it while I'm still laying on it, roll it up once to get the bulk of the air out, then roll it up a second time, folded as best I can. If any one has found a good process, please let me know.
I like Klymit products, this is my second Klymit pad. The other is the regular insulated V pad. Unfortunately, it just does not stay put; the wings definitely serve their purpose.
Would recommend to a friend.
