Thirty seconds with Michael Clarke.

Cricket has changed. Your box routine hasn’t.

If you’ve played any amount of cricket, you already know the drill. The X-Cup is the single-garment fix.

The old way: Jockstrap, undies, then shorts. Three layers to keep one piece of plastic in place.

The fix: One garment. The pouch holds your own box inside the brief, slipped in through a concealed opening at the front.

The old way: “Hang on mate, let me fix my box.” Before every single ball.

The fix: Front X-straps balance and press the box towards you, and rear balancing straps anchor it from behind, so it stays where you set it.

The old way: Sweaty, rubbing and tight when you need to be quick between the wickets.

The fix: 95% viscose from bamboo, 5% spandex. Breathable and sweat-wicking, with legs that don’t ride up and over 90% less odour-causing bacteria.*

  • 1 garment, not three
  • 90%+ less odour-causing bacteria*

Questions, answered.

Does the X-Cup replace my box?

No. The X-Cup is underwear designed to be worn with your own standard cricket box, which slides into the inbuilt pouch.

Will it stop my box moving?

The pouch, front X-straps and rear balancing straps are designed to support how your box sits. We don’t make performance or safety claims.

Is this protective equipment?

No. The X-Cup isn’t classified as PPE or impact-protection gear.

What size should I get?

The X-Cup comes in M to 2XL and has a fitted cut. If you’re between sizes, size up. It suits guys with thicker legs best.

What’s in the ODI and Test Series packs?

The ODI Pack is one X-Cup and one pair of crew socks. The Test Series Pack is three X-Cups and three pairs of crew socks. You pick the sizes for each.

How does the multi-buy saving work?

Buy two or more X-Cups and save 15%, or three or more and save 20%. You can mix sizes, and the saving applies automatically at checkout.

How do I wash them?

Take the box out first. Machine wash cold on a gentle cycle, with no fabric softener or bleach. Tumble dry low or hang dry, and don’t iron.

How does the First Pair Guarantee work?

We are so confident you’ll love your first pair of Step One underwear that if you don’t, you can keep them and we’ll give you a full refund. No questions asked. This applies to your first single pair purchase.
