I have been looking at them too. I'm thinking since I'm in a blind a little propanr heater is better (cheaper & less restrictive).

if you had to sit all day on a big bucks$ hunt in saskatchawan i might get one. a regular old sleeping bag might do the trick. last winter bow was in the low 20-s with 20mph winds and as long as i had 2 face masks on with pack boots and the 8 hour chemical hand warmers you can tolerate alot. i even have the light mesh vest that holds a bunch of heat packs around your front and back that just makes you feel all toasty.;) http://www.warmers.com/ItemDetails.a...oryID%7citemid

I think the "body suit" that 1shot put the link to is better for the money. Plus you could partially unzip the center for ventilation or not even use it for weather that isn't arctic.
