I wear the tee style undershirt and boxer style underwear. Soft, comfy, and decently cool in summer.

For socks: Under Armour over the calf https://www.amazon.com/Under-Armour-...ps%2C97&sr=8-3

Don't laugh; they're durable, stay up all day, aren't too hot even in summer, and while they aren't "compression" per se they are nice and tight and may help with circulation.
