Built for high-heat, high-speed racing — stripped to the essentials for serious performance.

Constructed from three precision-cut panels of ultra-lightweight French woven fabric, the briefs move cleanly against the body without weight or drag.

A waistband-free build is anchored by an integrated silicone grip system, locking the fit without pressure. Two bonded rear pockets carry up to six gels with zero bounce.

Designed for fast running, not to be noticed.

Laser-Cut

Minimises the weight of the garment, improves comfort and prevents the fraying of hems.

Ultra Lightweight

Extremely lightweight fabric and minimised construction ensures you hardly notice the garment on the run.

Sweat Wicking

Draws sweat away from the body fast.

Large Gel Pocket

Store up to 6 gels with large rear pocket.
