I'm a big guy, my thighs tend to rub together when walking.
I'm also a mechanic, so I walk a ton and sweat alot.
Normal cotton underwear stretch out early in the day and start walking up my legs, letting my thighs rub.
I tried the famous brand that makes these whose name sounds alot like "Dul**th", and totally loved them. They don't ride up and they wick great. But they are very pricey.
Jumped on Amazon looking for a less costly alternative and seen these.
Very glad I tried these, I love them. And I get 3 pairs for the price of 1 pair of the more famous brand.
They wick sweat great, stay put on your legs and waist, don't stretch out, and have a roomier area for your package, so there is no binding.
I'm sold on these. If your a bigger guy that works a real job, you gonna love them.
