"Can I use an Under Armour discount code on any product?"

"Most Under Armour promo codes apply to full-priced items only, excluding sale and outlet stock unless the offer states otherwise. Additional conditions such as a minimum spend or new-customer status may also apply. We recommend checking the specific terms listed alongside each code on this page before heading to checkout — it saves you from the frustration of a code that won't apply at the last hurdle."

"Can I use more than one Under Armour promo code per order?"

"Under Armour permits a single discount code per transaction, which means you can't combine the site-wide code 3DF with the student discount or the EXTRA10 outlet code on the same order. Pick whichever delivers the biggest reduction for your particular basket. If you're buying from the outlet, run both EXTRA10 and your student code (if eligible) through checkout to compare before committing."

"Does Under Armour offer a student discount?"

"Yes. Under Armour provides 20% off to verified students through a third-party verification service — you'll need a valid student ID to register and confirm your status. The resulting code applies to full-price products only and counts as your one allowed discount per order, so it can't be stacked with codes like 3DF. Before applying it, check whether any active promo codes on this page might deliver a better saving on your particular basket."

"When does Under Armour hold sales?"

"Under Armour runs sales at several points during the year, with Black Friday typically delivering the steepest discounts. Boxing Day and the January sales period also tend to bring significant reductions across the range. Outside these events, the outlet section at underarmour.co.uk provides year-round markdowns of up to 50% on a broad selection of stock, making it a reliable fallback when no seasonal sale is running."

"How do I get free delivery from Under Armour?"

"Spend £50 or more and standard delivery is free, arriving within three to five working days via FedEx or UPS. Orders below that threshold incur a £3.95 charge. A useful alternative: Under Armour offers free delivery to its pickup points on every order regardless of the total. If there's a convenient pickup location near you, it's an easy way to skip the delivery charge without padding your basket."

"What is Under Armour's returns policy?"

"Under Armour accepts returns within 60 days of purchase at no charge, provided items are in their original condition with tags still attached. Once the returned goods are received and inspected, refunds are processed to the original payment method. The 60-day window is more generous than many sportswear competitors, which typically offer 30 days. Full details and the returns portal are available in the returns section on underarmour.co.uk."

"Does Under Armour footwear use UK or US sizing?"

"All footwear on the UK Under Armour website is listed in British sizing, so there's no need to convert from US or EU sizes. Order your usual UK size across men's, women's, and kids' ranges. A detailed size guide is available on the site if you're between sizes or unsure about the fit."

"How do I contact Under Armour customer service?"

"You can reach Under Armour's UK customer service through three channels. Live chat on underarmour.co.uk runs Monday to Sunday, 8am to 10pm, and tends to be the quickest route for order queries. Phone support on 00800-82766871 is available Monday to Friday, 8am to 5pm. For less urgent matters, email customerservice.uk@underarmour.com — responses typically arrive within one to two working days."

"Why isn't my Under Armour discount code working?"

"If your Under Armour discount code isn't applying, check these common causes:\n\n1. The code only works on full-priced items, but your basket contains sale or outlet products\n2. Your order total falls below the minimum spend required by the code\n3. The code has expired or was a limited-time offer that's already ended\n4. You're trying to enter two codes at checkout — only one is allowed per order\n5. The code is restricted to a specific group, such as verified students, and you haven't completed verification\n\nIf none of these apply, use the report button on the offer card so we can investigate.\n"

About the Brand

Under Armour was founded in 1996 by Kevin Plank, a University of Maryland football player who was tired of sweat-soaked cotton training shirts. From a single moisture-wicking prototype grew a global performance apparel brand, now headquartered in Baltimore, Maryland, and listed on the New York Stock Exchange. The company operates in more than 100 countries, with a dedicated UK site serving British customers through localised sizing, pricing, and delivery.

The product range spans training tops, leggings, jackets, hoodies, and shorts, alongside a full footwear line and accessories such as bags, gloves, and hats. What sets Under Armour apart is its proprietary fabric technology: ColdGear Infrared® insulates for winter training, HeatGear® keeps you cool in summer, and a dedicated waterproof collection handles wet-weather sessions. Footwear on the UK site uses British sizing, removing the guesswork for domestic buyers.

Pricing sits in the mid-range for performance sportswear — bestsellers start from under £15, and the outlet section regularly cuts prices by up to 50% across men’s, women’s, and kids’ lines. The Project Rock collection, a collaboration with Dwayne Johnson, brings premium designs at sale-tier pricing. Student discount at 20% off is available with verified status, delivery is free on orders over £50, and returns are accepted within 60 days at no charge.

Between the promo codes on this page, the outlet markdowns, and the seasonal sales calendar, there’s rarely a reason to pay full price at Under Armour.

How to use

Click the offer card for the code you want — 3DF gives you 10% off full-price orders, while EXTRA10 takes an extra 10% off outlet items. The code copies to your clipboard automatically. Head to underarmour.co.uk, browse the range, and add your items to the basket. At checkout, find the promo code box, paste your code, and apply it. Check that the discount appears in your order total before paying. Only one code works per order.

Several deals on this page need no code at all. Free delivery activates automatically when your basket reaches £50, free pickup-point delivery applies to every order, and outlet reductions of up to 50% are already reflected in the listed price. Bestsellers from under £15 and new arrivals from under £25 are similarly code-free — just shop the relevant section and the prices are as shown.

Under Armour offers 20% off to verified students through a third-party service. Register with a valid student ID, and once confirmed you’ll receive a unique code. It applies to full-price items only. Since you can only use one code per order, compare the 20% student saving against any active promo codes on this page before checkout to make sure you’re getting the better deal.

If a code doesn’t apply at checkout or a deal doesn’t work as described, use the report button on the relevant offer card to flag the issue. We review flagged listings regularly and update or remove them promptly — it’s the fastest way to get problems sorted and keep this page reliable.

Shopping Guide

When is the best time to shop at Under Armour?

Under Armour runs sales throughout the year, with Black Friday typically offering the deepest cuts. Between those peaks, the outlet section is always live with reductions of up to 50%. We’d suggest checking the outlet first before looking at full-price stock — much of it is current-season gear marked down to clear, not outdated last-run leftovers.

Can I stack my student discount with a promo code?

No — Under Armour allows one discount per order, and student codes count as that one. Compare the 20% student saving against active promo codes on this page. For full-price orders, the student code beats both 3DF (10%) and EXTRA10 (outlet only). For outlet purchases, it depends on the basket value — run both at checkout and see which applies more favourably.

How do I get free delivery without overspending?

Standard delivery is free on orders over £50, otherwise it costs £3.95. If your basket sits just below the threshold — say £43 — adding a pair of socks or a small accessory is nearly always cheaper than paying the delivery charge. Under Armour also offers free delivery to pickup points on every order, regardless of spend, which is worth knowing if there’s a convenient location near you.

Is the outlet section worth my time?

The outlet is Under Armour’s permanent clearance section with markdowns regularly reaching 50% off across men’s, women’s, and kids’ ranges. It’s distinct from limited-time sale events, which feature steeper but shorter-lived discounts. For consistent savings, start with the outlet; for the biggest bargains, watch for Black Friday and Boxing Day, when additional reductions sometimes layer on top of existing outlet markdowns.
