My grandkids bought me that Primos Randy Anderson Predator Vest for Christmas, which has plenty of pockets, but one thing I found accidentally was that on the inside back portion, there is a velcro strap......pull it, and down flops a seat which pivots off the bottom back of the vest. Granted it isnt well padded, but still would keep your bottom dry. Along with that, they got me a turkey chair from SW which also has a back on it. I love my grandkids..... now if I could only convince the "boss"...
