Vis a Vis "Orvis" anything even the Brit's
love them. You have a 'problem, bring it back and we'll give you a new one.' Have yet to read a post where someone said 'different.' When they warranty, they mean warranty. Keeps the "Orvis Boys" happy? Bad pun intended, but you can see them 200 yards off.
As for waders, get the waist high ones. Other than minimal wading 'hippers' are useless. Belly-buttons will cover 95% of what you're going to do.
Chest highs are good for really crappy weather, but do you REALLY!!!!
want to wade much more than knee deep? Even with a wading staff in moving water? (Yes, yes, it makes good DVD material and that's about all. Yes, Yes I remember my hipper hight comment, but rain happens and at times you have to pick yourself around a fallen tree, etc.)
Example to illustrate the above comment. Steelhead like water 3 to 8 foot deep, given a choice. Soooo, you're thigh deep, how deep are you already?
