Question: are there vents on the top that open?
Document: The zippered and velcro windows make a lot of noise when you open them, so we usually open those beforehand and just sort of prop them closed when we leave to be as quiet as possible.The roof isn't water-proof; don't guess it's supposed to be, but just pointing that out. There are tiny holes in the material, maybe for ventilation. So, it offers some shelter from a light rain, but it drips right in in a steady rain.
This was perfect for my kids to hunt in they love it. They shot a 12 point buck and the other one shot a 10 point buck out of it.
This blind is well designed and built. It has improved corner windows that give you much better view than older  model of primos ground blind which i also have been using for past 5 years. So far i'm very happy with the quality of this blind.
This blind has plenty of room and so many window set ups. Excellent buy! I am planning on much more hunting with this this year.
Pro's: Lightweight easy to carryCon's: It comes with door and window zippers which are noisy. Some windows use a bungle cord to close and attach to this plastic like hook which is seemed to the fabric. When closing they make noise. Velcro shoot thru windows and we all know how noisy velcro is.
Item arrived in a timely manner. Made a great christmas present for the man and it fits two comfortably. If you plan on sitting in it you will need to get a barstool to go in it, that makes it the perfect height to shoot out of sitting. It is a little short for a 6ft man to shoot out of standing but would be great for kids
I left it set up on a hillside for over a week in the Pacific Northwest and it didn't budge even without the stakes.There are 2 convenient small pockets on the inside walls.The loops for adding foliage are awkward and using them will accelerate wear on the blind.
I am pleased with this purchase, after agonizing over getting this, a cheaper blind, or a treestand.This is a good solid, roomy blind. My son and I fit into it comfortably for several weekends.The Blind seems to be well constructed and sturdy.The windows are easily replaceable.
He has not opened it yet but this is what he wanted. If he is unhappy with it...we will contact you.
Bought this for my son and I to deer hunt from. It's very comfortable and quiet and large enough for both of us to sit in two fold-out chairs inside. It folds up fairly small and portable for moving it and is pretty easy to set up. If you plan to leave it setup in one spot, use the tie-down ropes or it will blow over with the wind.
Answer: yes
