When they say "Big & Tall" they mean fat people. I'm only 6'2"+. Mayo Clinic physical therapists lists me as having legs/arms of equivalent 6'10". There's not much anywhere for tall people. Not hunting, but if you're like me & went a lifetime highwater sweat pants & pajamas check out www.ForTheFit.com. At least you can keep your ankles warm while sleeping. Also, western wear jeans come in 38" & 40" inseam because it's in style to stack jeans on boots.
Good Luck & best wishes
Kuiu and Sitka have tall sizes in pants I'm 6'6" 260ish!??with 38 inseam and the Kuiu attack pants fit me great. Comfortable but not as Tuff as I would like to see for the price
This is an older thread, but my son likes Kings camo. Says it more reasonable than lots and fits his long legs and arms. Only has used it a couple years but does seem to be holding up well.
