Great Product


Kate (A.K.A iPack) and I bought these for our double end to ends of the Bibbulmun Track and Munda Biddi Trail here in WA. We tested several lots of gear before finally setting off for our leisurely 4000Km, 7 month trek. These BA bags were great. No zip jams, no cool spots and very little down loss. We paired them with BA Two Tracks pads and used silk liners as these could we washed out with Wilderness Wash when they got too unhygienic. The integrated pillow sleeve we stuffed with our down jackets to make a really comfortable pillow. The Downtek fill definitely works as it was tested by a leaky camp shelter. When we got wet from rain we just slept with our wet clothes body heat and great insulation meant by morning we had dry clothes to start the day. The temperatures ranged from 40C to -5C. On the hot nights we slept in just the liners and on the really cold nights zipped them together to share body heat, so were always comfortable. Would highly recommend them for comfort loving hikers like us, if used in the correct temperature range to suit. Treat the temperature rating stated as survival not comfort and you will be well pleased, like us.
