Andy Murray will mark his first singles appearance at Wimbledon in four years by wearing a new woollen kit.

The three-time grand-slam winner, 34, who has not played a singles match at the All England Club since 2017, will wear a jersey made from merino wool, which has become popular with some athletes for its ability to absorb a lot of moisture.

Players have not routinely worn wool for almost a century and it will be a throwback to the 1930s era when fellow Brit Fred Perry famously sported V-neck pullovers during his all-conquering spell on grass.

Manufacturers Castore say “no other fibre can match all of its natural benefits with exceptional breathability, thermoregulation and supreme softness next to the skin, helping players keep cool and comfortable on court”.

And Murray said on the firm’s website: “I work with the designers on every piece, with technical performance at the heart of the process. It’s important that the kit performs under the toughest conditions.

“I’ve been testing the kit for a few months now and am really happy with how it feels and performs. For me, the technical performance is vital. It’s also very important the kit is sustainable and I like the fact it looks and feels a bit different.”
