Step One discount codes and promo codes in November 2026
Browse verified Step One coupon codes and these latest vouchers to save more


Keeping the Step One offers here current is part of my role as a Senior Editor, and I joined CupoNation Australia in 2023.
My advice for keeping the warranty valid is to leave the flag label on each pair intact and avoid swimming in them. The 12-month warranty against manufacturing faults needs the label in place, and salt or chlorinated water voids it.
Bamboo underwear designed to stop chafing is the focus of Step One, made from 95% bamboo viscose with 5% spandex. Men's styles include trunks, boxer briefs, briefs and compression shorts; women's cover bikinis, full briefs, thongs, body shorts and a period range; and kids' Junior Trunks run from age 2 to 14. Men's sizes extend from S to 6XL, measured by waist in centimetres.
Trunk vs Boxer Brief vs Sport: Leg lengths run 4, 6 and 8 inches, with longer legs suiting long runs and rides. Choosing by activity means one style covers the job.
Snug vs relaxed: Men's styles are designed to sit fitted, and the size guide suggests going up a size when between sizes or for a looser feel, which avoids reordering.

Free standard delivery on every order makes Step One easy to try without padding your basket. Pair it with the 30-day First Pair Guarantee on a first buy, just keep in mind discount codes don't stack, and sale offers don't combine either.
First orders are the sbest pick with First Pair Guarantee. Students get 15% off but verify ypur eligibility first.
The easiest saving on the site is built into every product page. Choose a bigger pack and the price of each pair drops, with no Step One discount code needed.
On men's boxer briefs, a 4 pack takes 10% off each pair, a 7 pack takes 15% off and a 15 pack takes 20% off.
Tiers vary by style, so the same pack size can carry a smaller discount on women's ranges.
Pack pricing is the one saving that's always on, which makes it the baseline any code has to beat. Save the 15 pack for styles you already wear, since opened pairs can't go back for a change of mind.
If your first pair doesn't suit you within 30 days, customer service will either refund it or swap it for a new size, even though it's been opened and worn. Exchanges stay within the same range, so men's swaps for men's and women's for women's.
The guarantee covers your first pair only, not every pair in a bulk order. That makes it a low-risk way to settle your size or test a new cut before you spend on a pack.
Underwear is hygiene sealed, so an opened pair can't go back for a change of mind. Outside the First Pair Guarantee, returns work like this.
Pairs must be sealed, unused and in their original packaging.
Contact customer service before you send anything back.
You pay return postage unless the item is faulty or not as described, and that cost isn't refunded.
Sale items aren't refundable, and anything bought with a Step One code is refunded at the discounted price.
Sealed returns make the most sense for a whole unopened pack in the wrong size. On one or two pairs, postage can eat a big share of the refund.
Students can take 15% off their order by verifying with Student Beans, which then issues a personal Step One coupon code for checkout. Student Beans lists no minimum spend on this offer.
It's the code to use when you don't hold a bigger offer, and the better pick for a small mixed order, because 15% off single pairs beats the 10% you'd get from a men's 4 pack, without committing to four of the same style.
Delivery is free across Australia with no minimum spend and no Step One promo code needed. A single pair costs the same delivered as it does on the product page, so there's no reason to pad an order to dodge a fee.
Orders are dispatched within one to three business days, and metro deliveries on the east coast usually take another two to four. No express option is listed, so if you need pairs for a trip, order about a week ahead.
Every pair carries a 12-month warranty against manufacturing defects from the date of purchase, so a seam that fails early means a replacement, not a new purchase. Claims need the flag label intact, plus photos or the garment itself.
Wearing pairs inside out or in salt or chlorinated water voids the cover. Swimming in them is the quickest way to lose it.
Step One's own sizing advice says the men's range runs small, and women who sit between sizes should go up one. Getting this right first time saves more than it seems, since a wrong size in a pack means paying return postage or ending up with pairs you can't wear. If you're unsure, size up on your first pair.
