AeroFLX+ is for when you plan to sweat a lot. The Mens Pirate Black Marl AeroFLX+ Seamless Tee features body-mapped ventilation that provides air flow and breathability where you need it most. Backed by over 18 months of research and development we analysed athletes body temperatures through a range of workouts and built the fit, feel and function of the fabric based on their needs. A cutting edge performance needs cutting edge fabric technology, which is why we introduced Ionic+ silver yarns to keep you fresher for longer. Ionic+™ Technology Lightweight moisture wicking poly yarns are bonded with positively charged silver ions (that’s where the ‘+’ comes from) which neutralise body odour meaning you can go longer between washes. AeroFLX+ is our ultimate lightweight training fabric.
