The first one I love is Under Armour Boxerjock. This is, in my opinion, the ideal underwear for working out. They wick away moisture so you stay cool and dry. They are also very supportive. Everything stays where its supposed to while lifting weights or working on cardio.
Not only are they ideal for working our by wicking away the moisture and keeping everything in place but they look amazing on. I have never seen a guy wearing Under Armour that doesn’t look amazing.
You can find these at UnderArmour site.
