Are these good for running and the gym?

Yes for moderate activity. The stretch and moisture-wicking fabric handle runs and lifting, but pure synthetic briefs dry faster and offer more compression for long, heavy sweat sessions.

How does the cotton blend compare with synthetic boxer briefs?

The cotton-rich jersey feels softer and more breathable day to day. Synthetics like polyester-spandex dry faster and hold shape better through repeated hard workouts.

What sizes are available?

Nike lists XS through XL. The fit is close, so if you are between sizes, size up for more room in the legs.

How should I wash them?

Machine wash at 30 degrees Celsius and avoid high heat, which protects the spandex and the waistband elastic.

These are classic boxer briefs with a normal-to-low waist. Check the specific colorway listing for fly details, as Nike varies construction across lines.
