The Ultimate Daily Essential.

At Progress Running Club, we believe in the "Keep Running Positively" mantra, a philosophy that extends beyond the miles and into the clothes we wear every day. The Haleiwa T-Shirt by Sunray Sportswear is the embodiment of this mindset: a garment built with patience, heritage, and unparalleled quality.

Unrivled Construction Produced in Japan on antique circular knitting machines, some of the only remaining examples in the world, each Haleiwa tee takes over an hour and a half to craft. This slow, meticulous process creates a "loopwheel" fabric that is entirely seamless on the sides. Because the machines rotate so slowly, the cotton yarn is never under tension, resulting in a T-shirt that will never lose its shape, no matter how many times it’s washed or worn.

The Fit & Feel Drawing inspiration from classic 1950s sportswear, the Haleiwa features a slightly boxy, traditional fit. It is cut from a heavyweight 260gsm recycled cotton jersey that offers a unique, slightly uneven texture and a luxurious "fluffy" hand-feel that actually gets softer with every wear.

Whether you’re heading to a post-run coffee or navigating the city, the Haleiwa provides an elevated take on the humble basic. No external branding, no fuss, just the best T-shirt you will ever own.
