How a DFYNE discount code works
DFYNE runs on Shopify, and a discount code goes into the discount field at checkout, after you have left the basket and before you pay. The basket itself notes that shipping, taxes and discount codes are worked out at checkout, so the saving only shows up in the order summary on that page. Check the total there before paying: if the reduction is not listed, the code has not been applied.
The brand's own offers are the most reliable starting point. At the time of writing, the footer of the site invited shoppers to subscribe to the newsletter for 10% off a first order, and the newsletter is also where DFYNE announces new drops, colour launches and restocks. Because the store works on regular drops rather than constant sales, the UK catalogue was entirely at full price at the time of writing, so a markdown is the exception here rather than a permanent feature.
Rewards points are a separate route to a discount. Points are turned into a single-use discount code through the Rewards widget on the site, in blocks of 1,000, and the rules published by DFYNE say a minimum spend applies, points take up to 30 days to be credited after a purchase, and a rewards discount cannot be combined with another discount code. Treat that as the general rule too: assume one code per order unless the checkout accepts a second.
Keep an eye on what the free-delivery threshold does to your total. Delivery is free on UK orders from £30, and a percentage discount is normally worked out on the products, so a basket that only just clears £30 before a discount may fall below it afterwards. Gift cards are sold as digital cards and are paid for separately from any promotion, and returns are refunded for what you actually paid, discount included.
About DFYNE
DFYNE was founded in Glasgow in 2021 by Oscar Ryndziewicz, and the website names OLR Holdings Ltd as the company that owns and operates the brand. The founder story that has done the rounds in the business press is one of a very small start, funded on a credit card, followed by explosive growth: sales went from under £2 million to more than £13 million in the year to January 2024, and in 2025 the brand topped The Sunday Times Hundred list of fast-growing smaller companies, with sales reported at £66.8 million. It chose to scale from Scotland rather than move to London, and its public review profile gives an address in Uddingston, just south-east of Glasgow.
The range is built around women's training kit, and it is organised by collection rather than by fabric or activity. Each collection has its own feel. Impact is the firm, sculpting option with a scrunch and glute contouring, pitched at heavy lifting sessions. Defy uses a lighter, buttery-soft seamless fabric with invisible contour zones. Dynamic concentrates on bras and tops with soft straps and open backs, Origin on peach-soft minimal pieces, and Vision on straight-waistband flares and capris. Revive is the looser loungewear and layering line, stretching all the way to down jackets for winter.
Around those core lines sit a lot of cuts. Leggings come in standard and V-back versions, shorts mostly at a 4.5-inch inseam, and flares, capris, fold-over wide-leg pants and one-piece bodysuits with a built-in bra fill out the bottoms. A number of trousers and flares are sold in Short and Tall lengths as well as regular, and sizes on the catalogue run from XXS to XXXL. Roughly three-quarters of the UK catalogue is women's, and a large share of it is tagged as seamless, which is where most of the sculpting and scrunch detail comes from.
The men's side is smaller but has its own identity, again split into named ranges. Charge covers training shorts in 4- and 6-inch lengths, tanks and quarter zips; Stealth is the midweight joggers, hoodies and plain tees; Unbound includes a training tee designed to show a second colourway when the fabric stretches; Recharge is washed-look loungewear; and Signature is the logo-led hoodies, jerseys and track jackets. Accessories are shared across both sides: stainless-steel water bottles, shakers, gym towels, barbell pads, wrist and ankle straps, resistance bands, duffle and tote bags, caps and socks.
Prices on the UK store sit in the mid-market for gym wear. At the time of writing, a sports bra was typically around £37 to £41, a pair of 4.5-inch shorts about £42 to £46, leggings roughly £46 to £55 and flares £62 to £64, while the one-piece bodysuits were £73 to £76 and the long down jacket was the most expensive item at about £255. Nothing on the UK catalogue was marked down at the time of writing, which fits how the brand works: it sells through regular collection drops and colour launches, and popular colours often sell out before a restock.
Reputation is strong on paper. DFYNE's Trustpilot profile had a score of 4.8 from more than 10,000 reviews at the time of writing, with the large majority five-star, and reviewers often praise customer service staff by name and the fit of the leggings and shorts. The critical minority is worth reading too: complaints mention seams or printed logos that did not last, refunds that took a long time to appear after a return, slow replies at busy moments, and frustration at sold-out drops. The brand is not listed on Feefo. Its own product reviews run through an on-site widget that the shop controls.
Why shop at DFYNE?
- A women's range built on fit, not just colour — Most of the catalogue is women's leggings, shorts, bras and one-pieces, and the collections differ by how they fit and hold. Impact is firm and sculpting, Defy soft and seamless with a subtle scrunch, Dynamic built around strappy and open-back bras. That makes it easier to choose a fabric feel than at a store where everything is one generic 'performance' line.
- Short and Tall lengths on many bottoms — A good number of leggings, flares, wide-leg pants and joggers are sold in Short, Regular and Tall lengths, and sizes run from XXS to XXXL. For anyone who usually finds gym leggings bunch at the ankle or stop short of it, that is a practical reason to look here.
- Express delivery as the default — DFYNE calls express shipping its standard service rather than a paid upgrade. For UK orders it has used DHL's tracked express service with an estimated one working day, and the delivery charge drops away from £30. DHL's On Demand Delivery lets you reschedule, redirect or choose a pickup point once a parcel is on its way.
- 60 days to send things back, free — The returns window is 60 days, which is well beyond the legal minimum for online orders, and the store says UK returns are free through its self-service portal. The condition is that items are unused. There are no direct exchanges, so a different size means returning the first item and placing a new order.
- A home-grown brand shipping from the UK — The business started in Glasgow and orders ship from the UK, so there are no import duties or customs forms on a UK delivery and you are dealing with a company under UK consumer law. The terms name OLR Holdings Ltd as the operator, and customer service is reached through the support hub, chat and email.
- A proper men's training line — The men's side is not an afterthought. Charge, Stealth, Unbound, Recharge and Signature each have their own look, from 4-inch training shorts and tanks to midweight joggers, washed loungewear and track jackets. Accessories such as wrist straps, barbell pads, shakers and water bottles are shared between both ranges.
- Rewards that turn spending into discounts — The store runs a points-based rewards programme. Points come from orders, from reviewing items you have bought, from referring friends and from following the brand on social media, and they convert into a discount in blocks of 1,000 points. It is a slow burn, but for regular buyers it adds up.

More money-saving tips for DFYNE
- Sign up before your first order — The newsletter sign-up has offered 10% off a first order, and it is also where drops and restocks are announced first. Subscribe before building your basket, then use the offer on the order where it saves you the most.
- Build baskets past £30 — UK delivery is free from £30. A single pair of shorts or leggings already comes close to that on its own, so adding a pair of socks or a sports bra is often cheaper than paying for delivery on a smaller order.
- Size up on compressive bottoms if unsure — DFYNE's own guidance is that its leggings and shorts are compressive, second-skin fits: if you are between sizes, go up. Tops run slightly fitted, while seamless sets usually work in your normal size. Check the product's own size guide, since each style has one.
- Use the Short and Tall lengths — If standard leggings are usually too long or too short for you, filter for the styles sold in Short and Tall lengths. It avoids a return and is one of the practical advantages of this store over simpler ranges.
- Let points pay for the next order — Leaving a review on items you have bought earns rewards points, alongside points from spending and referrals. Collect them into blocks of 1,000 and redeem on an order that meets the minimum spend, remembering the rewards discount will not stack with another code.
- Move quickly on drops, or wait for the restock — Popular colours sell out, and DFYNE says tracking can lag during its busiest drops. If a colour has gone, the brand's socials and newsletter are where restock news appears; there is no point paying over the odds elsewhere.
- Keep the return paperwork together — Returns go through the online portal, take up to 18 days to reach the warehouse, and are refunded within about five working days after arrival. Keep proof of posting and the returns form with the parcel, since the complaints on public review sites are mostly about refunds that were slow to appear.
Frequently asked questions about DFYNE discount codes
Is DFYNE a British brand?
Yes. DFYNE was founded in Glasgow in 2021 by Oscar Ryndziewicz, and the website names OLR Holdings Ltd as the company that owns and operates it. Its public review profile gives an address in Uddingston, near Glasgow. Orders for the UK are shipped from the UK and the terms are governed by UK law.
How much does delivery cost in the UK?
At the time of writing, UK delivery was free on orders from £30. Below that, DFYNE's delivery page listed a charge of £1.99 for its standard service, which is a DHL tracked express service with an estimated delivery time of one working day. Check the delivery options at checkout, as rates can change.
Will I pay customs or import charges?
No, not on a delivery within the UK. DFYNE ships its orders from the UK, so a UK parcel does not cross a customs border and there are no import duties to pay on the doorstep. The customs information on its site only applies to orders going abroad.
How long do I have to return something?
DFYNE offers 60 days to return an item, provided it is unused, and it says returns are free. You start the return through its online returns portal. That is considerably longer than the minimum cancellation period that UK law sets for online orders, so there is plenty of time to try things on.
How long does a refund take?
The brand asks you to allow up to 18 days for a return to reach its warehouse. Once it arrives, DFYNE says it processes the refund within five working days and emails a confirmation, after which the money can take another three to five working days to show on your account. If nothing has arrived by then, contact customer service with your order number.
Can I exchange for a different size?
Not directly. DFYNE does not currently offer an exchange service, so you return the item through the returns portal for a refund and place a new order for the size or colour you want. If the item you need is selling fast, it can be worth ordering the new size first.
How does DFYNE sizing work?
Sizes run from XXS to XXXL. The brand says it generally runs true to size, but leggings and shorts are compressive, so it suggests sizing up if you are between sizes. Tops are slightly fitted, and seamless sets usually work in your normal size. Many leggings, flares and joggers also come in Short and Tall lengths.
What if my item is faulty?
Contact customer service with your order number, a description of the problem and photos or a video. DFYNE reviews faulty items case by case and may ask for the item back to inspect it. Under UK law, goods must be of satisfactory quality and last a reasonable time, and that right applies whatever the shop's own policy says.
Which payment methods can I use?
DFYNE's support pages list Visa, Mastercard and American Express, and the checkout supports buy now, pay later options. If something goes wrong with a pay-later plan, the brand advises contacting the provider directly, since they manage the instalments. Make sure your billing address matches your card, as a mismatch is the most common reason a payment is cancelled.
Can I cancel or change an order?
Only before it enters fulfilment, and DFYNE processes orders quickly. You can cancel through your account while that is still possible. The delivery address can also only be changed before fulfilment, although once DHL has the parcel you can often reschedule, redirect it or pick a collection point through DHL's On Demand Delivery service.
How do the DFYNE rewards work?
You collect points for orders, product reviews, referring friends and following the brand on social media. Points are redeemed in blocks of 1,000 through the Rewards section of the site, which turns them into a discount code. A minimum spend applies, points can take up to 30 days to arrive after a purchase, and the rewards discount cannot be combined with other codes.
What do customers say about DFYNE?
At the time of writing, DFYNE's Trustpilot profile scored 4.8 out of 5 from more than 10,000 reviews. Praise centres on friendly customer service and the fit of the leggings and shorts. The negative reviews mostly concern slow refunds after returns, the odd quality problem such as peeling logos, and sold-out drops.
