I bought one, here are my thoughts even though I only have one season on it
No flotation, I didn't want it.
I bought mediums, the shoulder straps for the bibs portion don't go short enough.
I wish the zipper on the bibs went higher up closer to the hip so I could put them off/on without removing my boots at the same time.
Too many pockets. I never thought I would say that. I think I'll lose things in the coat. I do like the big billow pockets to warm my hands in.
I love the hood, it has the right amount of coverage and visibility.
I wish the coat had a zip in/out liner.
Love the kneepads, my old bibs (Columbia waterfowl hunting) didn't and I never realized how handy they are.
Wish the bibs had different style of pocket. I wear the bibs much more frequently than the jacket.
