Comments about Zirkel SL 20 Sleeping Bag (800 Down):

i am a scoutmaster and i bought this bag because i was tired of carrying my big bulky bag and huge tent and inflatable air matress. i am comfort driven with minimalist tendencies. i use this bag with a big agness air core pad. together they pack down to slightly larger than my crocks. i was toasty on a 18 degree night with a silk bag liner. although we usually park near where we camp i now carry every thing on my pack and only have to make one trip.
