The Zayn men\'s active top is a great choice of outer layer for outdoor running. Lightweight, this style of top still offers you the coverage you need without any weight or bulk for optimum movement and comfort. Using a range of performance technologies, a combination of Duoskin and Quick Dry fibres reduce and manage sweat build-up to leave you comfortable and confident as you train. Additionally, an antibacterial finish stops bacteria from accumulating on the fabric for a longer-lasting piece of active wear. Contrast flat seams create a smooth structure for optimum comfort that won\'t irritate or chafe as you move. You\'ll also have a 1/2 zip neck that you use to create a high neck, when wanting to keep the chill off, or you can wear it down when seeking instant ventilation. With long sleeves as well, this style of top comes in grey with blue detailing.Size and FitFits true to size take your normal size
