You could just take them back to a bass pro and they'd allow you to exchange them on the spot. Only cost about $12 a pair too. After 2014 the quality dropped though unfortunately. They were made in America too.

>>2533750the more research I do into this the more I realize most people don't know what they are talking about. Clothing is a broke industry unless you are Nike or a fashion brand (Nike), in which case your prime focus is athlete chic and fashion.
There's Patagonia and Arcteryx whom tend to be two of the bigger forces pushing the future direction of function, but both have pushed society to synthetics since Patagonias partnership with MArtin Mills (polartec) is what created fleece, a synthetic fiber meant to imitate wool.
Wool has been on the decline since the 1970s, and unless it is like a twill, thin wool just isn't durable.
For any ecological, flame, and stink issues with polyester, it's more efficient as an insulation than wool. That polartec fleece too, like what swazi uses is durable too.
