These are $20 in CostCo if you have a membership, but they're phasing them out - once this batch is sold out they won't be restocking any more. They're $40 + s/h elsewhere, and I saw some people in an ultralight forum saying even though the stitching doesn't perfectly keep the heat in, they're still a great deal for the CostCo price. Then a friend wanted me to pick one up for them on the ride down today, so I thought I'd grab a few before the remaining ones at my store were all bought off and help get them to people who don't have a CostCo nearby, or don't want to pay for membership (as a matter of fact, I can easily make $30+s/h each for them on eBay).
