I bought one of these years ago, to replace my buffalo. I was very suspicious, as to me it looked like cheap rubbish.
But despite being basic, with no frill, it really is warm. The coldest ive used it to was -28, and as its synthetic it still works when wet. The builod quality isnt brilliant, but for its price, you get a warm bit of kit. I found the best way to stash it is not in the stuffsack, just loose, as it then seeps into all the nooks and crannies in your bergen.
Ive had to stitch it up a few times, but i would reccommend it.
One warning - my mate wore his, standing next to someone who smoked, and it went up like a roman candle! Be warned!
