--"a person's body weight could very well cause it to rippppppp the length of the hammock, putting both of you on the ground."
That would be a heck of a way to wake up in the middle of the night!
But, I'll take my chances. The nylon seems strong, I try to keep his nails clipped and he's on the ThermaRest which is covered by the pad sleeve. I'm more worried about the mosquito netting when he's getting in and out.
I don't have the shoulder squeeze/coffin/envelope problem mentioned. Atleast not with a ThermaRest to act as a spreader. It's very important to keep the crib stretched very tight between trees, as tight as possible so it doesn't sag and give wrap around problem.
Thanks for mentioning the Speers hammock. Since the Crazy Creek Lex Crib is relatively heavy for ultralight backpacking, I want a Hennessy A-sym UL. But, they're so expensive. Don't want to drop $130+ to knock 1.5 lbs. off my pack weight for the 3-4 trips a year when I can use a hammock. I think I'll take the Speers or other lightweight hammock with the Crazy Creek sil-nylon tarp for backpacking and reserve the Crazy Creek Crib LEX for car-camping and colder weather.
