I had a Frabill for awhile. On a trip out, it was below zero cold and windy and the zipper blew out. One of the bars on the frame broke next trip out.

Before last season, I got a Clam Nanook thermal. It's big enough to fish two comfortably. It's small enough to drag myself if I'm fishing alone and loads easy. Same conditions as when my Frabill broke down last year, I stayed warm. Easy to assemble and well worth the money.
