About a year back, we reviewed The Slanket - a blanket with sleeves that allows you to be warm and still have your hands free.
Gizmodo just did an article comparing several of the better known brands (If you read no further, take away this - they REALLY recommend against the Snuggie!).
They compare size, warmth, comfort, price, etc. They even cover the extravagent Blancoat - $300+ and made from Icelandic wool!
If anyone gets a Blancoat, let me know, I wanna try it out!
The Gizmodo correspondent wearing all four of the sleeved blankets - I might be wrong on this, but I don’t think they designed to be interoperable… Is there an interface standard for this sort of thing?
