Recommended underwear for men?

Basically I'm looking to get some underwear that fits these specs so my onebag journey is a bit easier.

• lightweight
• keeps odor down (like merino wool, etc.)
• can also be used for sports/athletics purposes (maybe like an under armour brief)
• boxer style (not boxer brief but that might be ok too)

I don't know if Smartwool merino ones fit the bill or if there are any better options (either cheaper or just overall better, etc.)
