The Birney men\'s active top is a great cover-up for outdoor training sessions as it will offer you the coverage and performance you need. Lightweight, as you perspire, Duoskin fibres work hard to ensure it doesn\'t sit on your skin by drawing it away so it can be evaporated while Quick Dry technology means the fabric will stay feel dry on. If that wasn\'t enough, antibacterial properties helps to regulate bacteria so the garment stays fresh and odour-free. With a 1/2 zip neck, you\'ll also be able to control how much air gets in and out allowing you fight the chill or keep cool. It also has some reflective printed logos that help others to easily spot you when out in low light. It also has a small rear zip pocket that is perfect for keeping your phone or keys in when wanting to stay hands-free. Designed using a brush backed fabric, the top has super soft feel that you will love to wear when outside running, power walking or making your way to the gym.Size and FitFits true to size take your normal size
