My Kuiu bag arrived Fri. Initial impressions are; light weight (2.07lbs in the stuff sack) Kuiu advertises bag only at 1lb 14oz which is probably true. Material appears to be the same as their Super down gear if you're familiar with it and compression is outstanding. Waterproof; I poured a glass of water on the bag, it puddles up immediately, let stand approx 1min with no sign of dampness after clean up. Down loft; the bag lofts up very quickly and thick. Roominess; it is a mummy style but not as constricting as some others might be, I do like the foot box with vertical room. Functionality; of course this was in house use, draft collar and draw string appear placed very well, the hood is nice for those who like to use that or could double aiding in pillow cushioning. The only con I can find right now and it's minor is the zipper snagging approx 10in from being fully zipped which appears to be from the extreme amount of loft pushing the tapped seam over, but otherwise the zipper works very well in all other areas. Zipper goes down nearly to the foot box allowing ease of entry, also zips up from the bottom to allow venting if needed. Overall very pleased to this point and looking forward to some nights in the tent in Sept.
