Fly opening in boxer briefs or not

Short answer: A fly is a practical detail, but it costs two extra seams against the skin. Many people choose against it for exactly that reason.

What a fly is

Two layers of fabric laid over each other at the front, giving an opening with no button. It is also called an opening or a front panel. It exists both with and without an extra crosswise seam.

The case for

It makes a trip to the toilet quicker, especially under overalls or work clothing where you cannot pull the waistband down. See bamboo boxer briefs for men.

The case against

Extra layers of fabric mean extra seams and a little more warmth in exactly that spot. With sensitive skin or heavy sweating, a style without is often better. See bamboo underwear for men and bamboo clothing for men.
