Castore Active Deals, Sales & Codes in August, 2026

Castore is a British sportswear brand founded in 2015 by brothers Phil and Tom Beahon in Liverpool (citation:2)(citation:4). The company designs performance clothing across running, training, golf, tennis, and football — with current kit partnerships including Newcastle United, Wolverhampton Wanderers, and the McLaren F1 team (citation:6)(citation:4). Tennis star Andy Murray became an investor in 2019, and the brand now sells in over 40 countries (citation:2)(citation:3).

The product range covers everything from lightweight running jackets and training trousers to golf polos and licensed club shirts. Outerwear typically sits between £180 and £245, while shorts start around £95 and polos feature technical fabrics like AerTek for moisture management (citation:1)(citation:3). What sets Castore apart operationally is a supply chain centred on Europe rather than the Far East — production happens in Portugal using Italian fabrics, which allows faster turnaround than the 18-month cycles typical of larger brands (citation:4)(citation:6).

That European-first approach feeds into some distinctive features worth knowing about. Castore uses 3D printing and seamless construction techniques, and its AerTek technology is built into products like the men’s golf polo range for breathability across long rounds (citation:1)(citation:4). The brand also offers 15% student and key worker discounts on full-price items — though key worker codes exclude Teamwear (Rangers, Newcastle, and Wolves shirts) and Pro Tex clothing (citation:3). A referral programme gives both parties 20% off.

Between the current codes on this page, the active sale section with up to 50% off, and the demographic discounts available, there are several routes to a better price here — worth bookmarking if you’re shopping for technical sportswear at a premium tier.

Are Castore codes ever worth more than the sale prices?

It depends on what you’re buying. Our tracking shows codes like WELCOME15 (15% off first orders) and SURVEY20ML (£20 off orders over £30) can sometimes beat the percentage discount in the sale section — particularly on items that are only reduced by 10–20%. We’d suggest comparing the code discount against the sale price before checkout. The 30%-off-on-£100-plus code is especially useful when you’re bundling items that aren’t yet in the sale.

When does Castore discount the most?

Based on historical data, December sees the heaviest code and sale activity, followed closely by Boxing Day and January, where we’ve tracked discounts up to 70% off. Black Friday and Cyber Monday regularly feature 50%-plus reductions across most categories. Castore runs active sales for roughly 39% of the year, so there’s usually something available — but if you can wait for one of the peak windows, the savings jump significantly.

Can I combine offers for maximum savings?

Castore only allows one discount code per order, so you can’t stack codes together. However, you can combine a code with free delivery (currently triggered at £60) and shop during a sale period to get the best effective price. The referral programme is another angle — your friend gets 20% off their first order while you receive a 20% code to use on yours.

What catches people out when using Castore codes?

A common issue we see is that some codes only apply to full-price items, which means they won’t work on sale stock. Student and key worker discounts both carry this restriction. Key worker codes also exclude Teamwear — Rangers, Newcastle, and Wolves shirts — and Pro Tex clothing. Always check the T&Cs listed on the offer card before building your basket.
