I love my ENO Doubles (have several of them) and they cradle my 220# 6'2" bulk so I like a sedated baby. I deal with CBS most times by zipping my sleeping bag "around" the hammock like a full coccoon. This can be somewhat restrictive to a full diagonal lay though and when I saw the Reactor I thought my quest for cold weather hangs was solved.
Read the specs ye tall ones...
At 5' 6" across there is NO WAY you will sleep even near flat without your feet, and lower legs, falling from the hammock. It's just not possible to get a good "foot pocket" on the diagonal, and sleeping along the centerline is... well we all know about that.
Warm, heck yeah! If I was under 6' this would definitely be a "go to" hammock.
By the way, I stuffed it with a REI Airrail 1.5 self inflating sleeping pad. I've no doubt it would handle sub-zero temps with the right over quilt (sleeping bag, quilt, blanket, etc.)
, just not for the longer legged of us...
