"I wore this to the gym 3 days in a row. No smell. No itch."

"In a pinch, I can wash things in the shower too."

"I've worn the merino tee for ~10 days straight with no smell though."

"As a (fragrant) side note, I've haven't used soap or shampoo for two years."

I hate to break it to you dude, but I guarantee that you smell to high heaven and you've just gotten used to it.
