Peapods aren't just for deep Winter. I've slept comfortably in mine in the 50's as well. All that you have to do is open some of the velcro to vent. As far as heavy and bulky goes, the 20* pod only weighs 38 ounces which compares favorably to most TQ/UQ combinations. With the 900 fp down, they also compress quite nicely. The volume of mine compares to a fractional UQ and TQ combination.
For comparison, a 20* Hammockgear Burrow and a 20* Hammockgear Phoenix weigh a combined 35.7 ounces. That's just about two ounces difference between that and a 20* Peapod.
A Peapod isn't for everyone, but don't buy the stories about being heavy and bulky. The actual weight and pack size do not support those conclusions.
