I think that frabil has a better zipper than the clams... If you are in mqt again you can check out the frabils at dunhams...i don't think the one in esky has room for anything.. this is the 3 person which would be bad azz if weight is no restriction as well as money... The fish trap thermal x's are very nice but also very expensive. This link is for frabil but check out the clams and otters also..Another thing, the seats in a frabil fold up and go inside the sled, the clams are attached taking up more space when packed.
