The C4M Boost bikini brief brings a bold, confident look with its soft black leatherette finish and a low-cut front. An ergonomically designed pouch shapes and supports, while the stretch fabric moulds neatly to the body for a close, flattering fit.
Made from 90% polyamide and 10% elastane, this brief balances elasticity and support so everything stays in place. Soft seams keep it comfortable against the skin throughout the day. Shown here in a medium size and a matte black finish.
The C4M Boost bikini brief is designed to make an impression, pairing a sleek black leatherette look with a low-cut, contouring cut. Its ergonomic front pouch is shaped to enhance and support, while the fabric blend moves easily with you for a fit that feels as good as it looks.
This brief takes its cue from a sleek black leatherette aesthetic, giving it a bolder, more striking appearance than everyday underwear. The low-cut front sits neatly on the hips for a flattering silhouette, and the ergonomically designed pouch is shaped to enhance and hold everything comfortably in place. It is a piece built to attract attention while still working as a practical, wearable brief.
Made from 90% polyamide and 10% elastane, the fabric offers a considered balance of stretch and support. That combination means the brief moulds to the body without feeling restrictive, giving a close fit that stays put through movement. Soft seams run along the edges to reduce rubbing against the skin, so it remains comfortable over longer wear rather than just for show.
This listing is for the medium size, cut close to the body for a supportive, contoured fit. As with all fitted underwear, the elastane content allows a degree of give, so it flexes with you rather than sitting loose. If you prefer a snug feel that shapes and lifts, this style is designed with exactly that in mind, holding its shape through the day.
