If you're a walk hunter, when you need to sit for short periods of time, all you need is our 3/4" thick model to get you off the damp ground. If you sit for more than 15 minutes at a time, then you want the thicker 1.5" Invision Camo Therm-a-Seat, that adds even more support. If you're looking for super comfort, then you'll LOVE our 2" thick "Comfort Cushion" Therm-a-Seat, which has our new Optipoly Comfort Foam sandwiched between our New Softek closed cell foam outer layers. Perfect For: Deer, Turkey, Duck and Bear Hunting! ----- NEP Outdoors - Keeping Hunters Warm, Dry and Comfortable Since 1985!
