Care Instructions + -

To help preserve the quality of your garment, we recommend turning it inside out or placing it in a wash bag before laundering to avoid friction with abrasive surfaces.

Use a gentle cycle or hand wash in cold to warm water, and opt for a mild liquid detergent, ideally eco-friendly as it's gentler on fibres. We also suggest line drying in the shade to maintain the fabric's integrity.

Perfect for an Active Lifestyle
These briefs hit the mark for fit, comfort, function, and style. Material is soft, breathable, and quick drying when things get sweaty. Fit is supportive with the right amount of coverage—briefs move with you without riding up or bunching, but give comfortable coverage. The pouch is perfect for ample room, support, and style without being too “forward”. Great selection of colors. Perfect for work or play.

Perfection
Material that stretches to fit guys with a bit extra in the front. I often have to wear a large to fit the front in but then the waist is too big. I have a size small waist and love these and bought several more pairs
