UA Seamless Run Long Sleeve

£45, underarmour.co.uk

This is the best-looking top we tested, and the aesthetic is backed up with some technical specs that make for a top-of-the-range long sleeve. All-over mesh ventilation helps you keep your cool, and there are very few seams so chafing – an issue with some of the more budget buys out there – won’t be an issue.
