Query: Great for scent control and warmth

I've purchased 3 of these blinds and absolutely love them. Keeps the wind and rain off of you and really helps control your scent being released. I've hunted from tree stands, etc. but these ground blinds have proved to be my best locations to hunt from. You can relocate them easily from year to year; unlike a lean-to or ladder stand. If you never popped one of these things opened before make sure to read the instructions carefully; it's a little hard to understand initially but once you've done it, you'll never have any problem. Practice putting it up and taking it down in the back yard before going to the hunt site.
