I bought my first sailboat from an old geezer who summed it up pretty well. When I told him I planned to go to K-Mart and buy some cheapo pots and pans for the boat, he said: If you buy quality, you only pay once; if you buy crap, you pay for it every time you use it.
Anything you'll use every day or even once in awhile in a crisis, whether it's tools, fishing gear, clothing or boots, you should get the best quality you can afford. In the back country, you can't just jump in the car and get a replacement at WallyWorld. And a malfunctioning reel, busted rod, leaky boots, or a hole in the crotch of your only pair of britches can really spoil what should have been a wonderful trip.
If you get something on the cheap, get at least two so you'll have a replacement when the first one goes south. Plus, when you figure like that, the quality piece doesn't look quite so expensive since you only need one.
For britches and shirts, Carhartt is still pretty solid quality. LL Bean, not so much.
IMHO, FWIW, Crusader
