Wow, the first two nights in my Clark NX-250 with my new 20° full Zepplin uq and 40° Flight Jacket tq were blissfully cozy, comfy, and restful. The Zep went on super-easy and formed an instant tight seal underneath the hammock when I routed the ends underneath the head and foot hoops. As soon as I laid in the hammock I was totally snuggled in warmth by the Zep that came up several inches above my shoulders to the Clark's Weathershield/bugnet zipper. Temp only got down to mid 40s so I slept in my lightweight silk night shirt and shorts with the Clark's integrated Weathershield open half way and the tq only pulled up to mid chest. Not having a pad slipping around under my feet (though a ENO Hot Wings SPE had helped under the torso) and the lack of constriction by a sleeping bag was all I hoped it would be. Oh, and I stowed all my clothes in the storage pockets underneath the hammock (but above the uq) and they were warm as toast in the morning chill when I slipped them on; Priceless.
