Four core cuts: CX01BR brief for classic coverage, CX76BR sports brief for secure active fit, CX68BR trunk for square-cut short-leg coverage, and CX94BR boxer brief for extra leg coverage.

What makes the fabric unique?

FlexMode’s premium Italian ribbed fabric combines generous stretch, breathability and moisture-wicking comfort. It moves with your body while maintaining a supportive, flexible fit for active days.

How do I find my size?

Measure around your waist just below the hip bone, then use the Cocksox size chart; do not assume your usual brand size.

Which pouch should I choose?

Contour holds closer for active movement; if comparing styles, Original gives more lift. Confirm the specific product’s pouch.

How should I care for this collection?

Turn inside out or use a wash bag. Hand-wash or machine-wash on a gentle cycle in cold to warm water with mild liquid detergent. Line-dry in the shade; avoid tumble-drying.

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.
