I've used them a little bit. Most of them have zip-open windows; I don't know if any that don't but that isn't saying much.
I really don't use them as "portable" anymore because they stick out like a sore thumb. I do, however, brush them in early in the season and leave them out for its entirety so the kids and I can hunt out of them. Deer notice them RIGHT AWAY and stare at them as you'd expect. Turkey don't care.
They also greatly restrict your lines of sight & your ability to hear, making it easy for animals to sneak in unnoticed.
