Frequently Asked Questions
Trunks, which are a hybrid between briefs and boxers, offer a balance between snugness and freedom. They provide adequate support without being too constricting, making them a popular choice among many men. Briefs, on the other hand, offer a tighter fit, which some men may find uncomfortable.
MUJI boxers and briefs for men are generally made from lyocell, cotton or a blend of both. Lyocell offers a silky-soft, breathable feel with excellent moisture-wicking and is slightly more sustainable than cotton. Whereas, cotton provides classic softness but retains more moisture.
