I just ordered one today , I ordered the ' Wiggys Superlight' Zero degree mummy bag . I've been reading and getting info for the last 6 months and just spent the $180.00 which includes free shipping . Reviews are good for the most part although there are a lotta Wiggy detractors on all the hunting and survival sites where I've been reading reviews . --- Super Light --- I was going to get a Western Mountaineering or Feathered Friends Down bag but I like synthetic and its a lot cheaper . If this bag fails in expectation I still might go high end Down if I have to .
