Anyone tried one of these? I'm looking at buying one for backcountry hunts but thought I should do a little more research first. I'm 6ft tall and measure 60" around the shoulders and arms. I'm looking for a good lightweight bag. I plan to use it in a Kifaru Sawtooth floorless shelter with my Seekoutside bathtub floor under the bag. I know down is lighter but I thought I could dry a synthetic bag faster with sun and wind, or heat from the Kifaru wood stove if it ever got wet. The bag weighs 2lbs 4.5oz with it's stuff sack. Thanks!
