About the Brand

Step One started in Australia in 2017 as a direct-to-consumer underwear brand before expanding globally, including a dedicated UK site. They focus on making ethical, high-performance basics for men, women, and kids. Rather than using standard cotton, the brand relies on organically grown bamboo viscose to create garments that are significantly softer and more breathable.

The core range covers everything from men’s boxer briefs and trunks to women’s bikini briefs, body shorts, and period underwear. Prices generally start around £9 for junior trunks and £12 for women’s bikini briefs, scaling up to £16 for specialist items. What sets them apart from standard high-street multipacks is the technical construction. Many styles feature anti-chafe Ultraglyde panels and 3D comfort pouches, targeting people who struggle with friction or overheating during the day.

Beyond the fabric, the brand backs its products with a 30-day First Pair Guarantee. If the fit or feel isn’t right, they offer a full refund on your initial pair, which takes the risk out of trying a new material. They also run a robust referral scheme where both the referrer and the friend get substantial perks, alongside regular clearance events dropping prices by up to 50%. These advantages, paired with the voucher codes listed below, make this page worth bookmarking before you refresh your top drawer.

Shopping Guide

When is the best time to buy Step One underwear?

While they run a permanent clearance section with reductions up to 50%, the deepest discounts usually land around Black Friday, Easter, and the January sales. If you need to restock immediately, signing up for the newsletter guarantees 20% off your first order, which often beats waiting for a seasonal event.

How do I combine offers for maximum savings?

Stacking codes isn’t generally permitted on their checkout, so you have to choose your discount wisely. We suggest using a percentage-off code like R20 on full-price multipacks rather than clearance items. Since clearance prices are already heavily marked down, a flat 20% off a £15 full-price pair usually yields a better absolute saving than applying it to a discounted trunk.

Is the First Pair Guarantee actually worth it?

Absolutely. Bamboo viscose feels very different from standard cotton, and the fit can take some getting used to. Because the 30-day guarantee offers a full refund on your first pair if you aren’t happy, it removes the financial risk of trying the fabric. We recommend buying just one pair of boxer briefs to test the anti-chafe Ultraglyde panels before committing to a larger multipack.

Should I buy direct or from Amazon?

Buying direct from uk.stepone.life is almost always the better move. Not only do you get free UK delivery and access to exclusive discount codes, but you also qualify for the First Pair Guarantee and referral rewards. Third-party sellers on Amazon rarely honour these brand-specific perks, leaving you stuck if the sizing is wrong.
