High-leg sport brief with cotton stretch structure and athletic mobility

The C-IN2 HARD//Core Sport Brief is built for guys who want less coverage and more freedom. Cut high through the leg, this streamlined silhouette opens up the thigh for mobility while delivering a bold, athletic profile that feels confident and intentional.

Made from a soft cotton–elastane rib knit, it blends vintage-inspired texture with modern stretch for breathable, everyday comfort. A sculpted 1-ply contour pouch provides lightweight support, while dyed-to-match rib knit binding and a wide 2" engineered logo waistband keep the finish clean, controlled, and purposeful. Minimal coverage. Maximum presence.

Packaging Disclaimer
We tried to do better for the planet, but this one didn't work out. To reduce our environmental impact, we packed select underwear styles in this collection in compostable bags. Some of these bags broke down sooner than we expected, so yours may arrive torn or damaged. We're sorry about that.

The underwear inside is brand new and unworn. If it's a gift, the bag may not be gift-ready. All other C-IN2 products are unaffected.

Reviews Summary
Customers say these sport briefs offer excellent fit and comfort with a supportive ribbed fabric that feels soft yet durable. The wide waistband sits higher than typical underwear, providing welcomed support and a secure feel. The roomy pouch accommodates well without being restrictive, and the high-cut leg openings work particularly well for those with larger thighs. Many appreciate the athletic styling and how the cut enhances their appearance. The material wicks moisture effectively and maintains its shape after washing. While most find the sizing accurate, one reviewer noted inconsistent sizing across different styles, and a few mentioned the waistband can roll or that sizing up might improve comfort.
