Is there a Castore discount code right now?
Yes, though the steadiest savings come from verified schemes rather than a public promo code. Students and graduates get 15% off after a quick check with GoCertify. Key workers get the same 15%. Both groups also get an extra 5% off the secret sale. Seasonal sales add extra money off archive lines on top.
From a Liverpool kitchen table to the F1 grid
Two former athletes, brothers Tom and Phil Beahon, founded Castore. The first orders were packed by hand at their mother's kitchen table in Liverpool. Today the brand kits out football clubs, Test cricketers and Formula 1 teams. You can buy training tops, shorts, jackets, golf polos and fanwear for men and women. If you like bolder British gym wear, compare Montirex as well.
Timing your order
The archive sale and Steal of the Day cut older lines by up to 70%. Try your voucher code in the basket, then compare it with the sale price on the same item. UK delivery is free over £60 and takes two to four working days. Spend £150 and next day delivery is free too. Returns cost nothing within 28 days of delivery. Klarna lets you pay in 30 days or split the bill into three. For women's activewear with its own sale, have a look at Sweaty Betty.
