Build your everyday essentials

Start with the pieces you reach for every day. Browse Acacia’s men’s undershirts for tank and short-sleeve styles, explore men’s underwear for boxer shorts, trunks and long boxers, or choose a coordinated look from our men’s sets.

Prefer pure cotton? You’ll find 100% cotton boxer shorts and selected undershirts. For a closer fit with stretch, explore tanks, trunks and long boxers made from 96% cotton and 4% Lycra. Choose the cut that suits you, and check each product page for its fabric composition, sizes and availability.

Buying more than one? Visit our men’s offers for multipacks. If an offer says “random colors,” you can choose the size but not the colors; shades may repeat.
