We have our own online club shop from which members can purchase HHC club kit direct. We're using Welwyn-based Tylers Sportswear, who run similar shops for St George's School, Harpenden Cricket Club and WGC Hockey Club, among many others. Our kit is still Grays. If you are ordering anything, I recommend that you check sizes with a teammate who has kit as some items, particularly skorts, have been said to come up very small. The size guide is available on our club kit page, here.
You'll find the store here.
