Step One Clothing Discount Codes July 2025

Underwear isn’t something most people like to talk about publicly. Or even think about much, for that matter. You tend to notice it only when it’s wrong - bunching, riding, cutting circulation off at the thigh like an overeager tourniquet. So it’s mildly surprising, though not altogether unwelcome, when a brand builds a reputation for getting it right. Step One, the Australian-origin underwear label that’s gained traction in the UK and US, largely owes its growth to word-of-mouth and a relentless social media presence that flirts with oversharing. Now, with the return of its popular "Black Mambas" line and a discount-laced push for new signups, the brand is worth a closer look - not just for what it offers, but how it wraps comfort in marketing and bamboo.

The Basics - Boxer, Brief, Mamba

Step One specialises in bamboo-fabric underwear that’s breathable, stretchy, and designed to ward off the less glamorous side-effects of existence (sweat, chafe, regret). The core men’s lineup includes several iterations of boxer briefs - standard, front-fly, sport, trunk, long - each named after fruit or innuendo. "Juicy Plums," "Smashed Avo" and, yes, "Butter Nuts." A sense of humour, here, is part of the compression.

The returning "Black Mambas" are essentially a classic black version of the standard boxer brief, selling for **£15**. That’s mid-range - not budget, not luxury. All Step One underwear uses organic, ethically made bamboo viscose, theoretically cooling and anti-microbial. Anecdotally, the fabric does feel softer and more breathable than typical cotton-poly blends. It’s the kind of touchpoint that turns an average Tuesday into a slightly above-average one.

Fit and Feel - Not Quite Tailored, But Close

Fit is where Step One earns its keep. The boxer briefs come with a 3D pouch, mid-thigh leg length, and what the brand calls "ultraglide" panels between your thighs to cut down on friction. For most, they stay in place during mild activity - walking, commuting, overthinking - but may ride a bit during workouts depending on your shape.

As with most "universal" size charts, results can vary. The fabric’s elasticity allows some forgiveness, so most people seem to find a size that works. But as with any relationship built on first impressions and elasticity, the second date might go differently. Fortunately, Step One's "First Pair Guarantee" allows refunds on the first worn pair if it doesn’t work out - no uncomfortable questions asked.

Deals, Discounts, and the Usual Strings

At the time of writing, Step One is offering free UK shipping on all orders. Prices for men’s underwear start at **£15**, with a few fly-equipped or limited edition options stretching to **£16 or more**. Women’s styles - like the SmoothFit Thong or Body Shorts - range from **£10 to £19**, depending on coverage and colour names. (Yes, "Rosé All Day" is technically a shade now.)

Occasional bundle deals surface, and newsletter sign-ups may net a small code - usually a few quid off. Worth noting: codes don’t stack infinitely, and promotional offers are typically single-use. You won’t game the system here unless you’re both persistent and very forgetful with email addresses.

Shipping, Returns, and the Fine Print

Shipping is free (in the UK), no minimum spend. Returns are accepted on unopened pairs, with the "First Pair Guarantee" covering the one-time get-out-jail-free option. Customer support is, reportedly, available 24/7, though response times may skew closer to civilised hours. Exchanges are fairly smooth, assuming you haven’t removed all the tags in a hurry.

Orders usually arrive within a few working days. Packaging is minimal and discreet - in case one’s neighbours should care what soft bamboo-based decisions you're making.

Verdict: Reliable, Reasonably Priced, Slightly Smug

Step One isn’t revolutionising underwear. It’s just making it less annoying. Which, frankly, might be enough. The prices are proportional to the quality, the marketing is cheeky but not insufferable, and the product almost always feels better than what you were wearing before.

Still, you’ll either appreciate the flashy names and lifestyle lean or see them as an overcorrection. (Wearing something called "Scorpions" while filing taxes feels mildly self-deceptive.) But underneath the branding, the design is solid. The fabric holds up. And the guarantee means you don’t have to lie to yourself - or your thighs - after trying.

So no, you don’t need bamboo underwear. But as with many mildly luxurious upgrades - espresso machines, noise-cancelling headphones, a second charger - it’s hard to go back once you’ve tried it. Or at least, harder than you'd expect from a product that rarely leaves the house.
