Military uniform undershirts. The second most sweated in clothing next to used Silkies.
These are varying shades of OD, FDE, and tan undershirts from PX favorites such as Soffee, Duke, and Dri-Fire. Some have bleach stains because grunts don't know how to launder. You'll get a mix of polyester and cotton blend shirts so when in doubt, order one size up.
