About Step One Promo Codes & Cashback

Step One makes ethical underwear from bamboo viscose, a fabric that’s softer than cotton and kinder to the environment, with ranges for men, women and kids. Every order comes with a First Pair Guarantee, so you can try a pair risk-free and get a refund if it isn’t right for you.

Since a full underwear drawer refresh can add up, shoppers regularly use a Step One discount code when stocking up on new packs across the range.

How to Save at Step One

  • Sign up to the Step One newsletter for early access to offers and new product launches.
  • Buy multipacks rather than single pairs, which usually cost less per item.
  • Check the clearance section for discontinued colours and prints at reduced prices.

Take advantage of the First Pair Guarantee if you’re unsure about sizing, so you can try before committing to a bigger multipack order. Applying a discount code on a multipack is the best way to maximise your saving per pair.
