BN3TH partnered with runner and artist Lucas Beaufort on the Pro Ultra Liner Tight with Pocket to fuse real performance needs with his deep connection to movement. While inspired by running, the liner is built for all athletic pursuits, delivering versatile comfort and freedom across training, gym, and high-output activities.

The Pro Ultra is built for maximum training and elite performance, crafted from super-premium lightweight fabric that’s highly breathable, supportive, and silky smooth. Designed with The Original 3D Pouch, it keeps everything separated and supported for next-level comfort during intense movement. A fold-over secure pocket provides reliable storage that stays in place while you move

The fabric is a breathable, moisture-wicking polyester blend mesh featuring Ionic+® anti-odor technology that does not wash out.
