"Not a big fan of ground blinds or pop ups...I do have a Double Bull. It has one issue to me, {other than the fact that they are now owned or made by Primos} for the money, and they want too much, it is not waterproof at all, In fact, sitting in mine during a rain is like being in the shower. Water drips right thru. maybe they tried to make it breathable, I don't know. Mine is pre- Primos. Primos is a name associated with Chinese junk and pi$$ poor customer service. I just think that for $400 you shouldn't be sitting in the rain and the material is so porous even waterproofing wont help."
