>>556833they're bulky but mine is pretty light, considering how insulating it is. i was in it in abuot 15ºF one night and was so warm i just needed a fleece blankey over the top of me. mine weights 1320g, which is just under 3lbs. Oh well! a lot of the time though you don't need both the underquilt and a sleeping bag, just the underquilt and a deent blanket for your topside. the underquilt takes a little practice though, if it's too tight against you you'll get cold spots (coldbutt) so you have to make sure it stays nice and loose and just keeps a good warm air layer around you.
