BUILT FOR THE PUMP. MADE TO LAST.

Welcome to Sixthfit, an Australian gym clothing brand born from frustration and built for durability. We’re here because, quite frankly, we were sick of pump covers that lost their quality after just a few washes.

If you lift, you already know. You find that perfect oversized tee, the one that makes you look and feel unstoppable in the gym. But after a couple of rounds in the wash, it fades, stretches, or worse—thins out like cheap tissue paper. We had enough.

So we made our own.

PREMIUM QUALITY. NO COMPROMISES.

At Sixthfit, we engineered the ultimate pump cover—heavyweight, durable, and built to last. No thinning, no fading, no disappointment. Just a solid oversized T-shirt that keeps its form, session after session, wash after wash.

Because when you put in the work, your gear should keep up.

WHY "SIXTHFIT"?

The name is a reminder that growth never stops. You don’t just hit the gym for the pump—you do it for the next level, the sixth gear, the mentality of pushing beyond limits. Our clothing is built with that mindset.

OUR PROMISE TO YOU

• Heavyweight fabric that won’t thin out
• Oversized fit for the perfect gym aesthetic
• No-fade material that stays fresh after every wash
• Australian-owned and designed

Whether you're hitting PRs or just throwing on a tee for the day, we've got your back—literally.
