Thanks to Grannyhiker for the correction on the Contrail. I assumed incorrectly there was a Contrail II! Oops.
I agree, too, that the Contrail, Squall, etc. are not good for socializing or all-day camping, rather for sleeping only. There is a slight weight penalty for any extra room. How they’ll work for you depends on your needs and style.
Hey–at 24 oz each, you might consider two Contrails! Might be good for mental health. I really like my hiking partner, but I think it’s good for us to sleep in separate shelters. I know I don’t snore (hah) or fart (HAH!). And if for some reason one of us needs to leave the trail, or even wants to take an alternate route or pace and meet up later, we have the flexibility to do so.
