Whether you're showing up to the studio or embracing the great outdoors, these men's winter activewear picks are all you need for a January reset.
New year, new you? Or at the very least, new threads. January is the time for resolutions, and if one of yours is to get back into the gym or up your mileage on the pavement, then a fresh kit is one of the best ways to set yourself up for success. It’s no secret that showing up is half the battle, and when you’re decked out in performance-driven, stylish activewear, you’re already ahead of the game.
Gone are the days when you could roll into your session in an old tee and baggy joggers. Today’s activewear is as functional as it is fashionable. Modern pieces are designed to enhance your performance — with breathable fabrics, moisture-wicking technology, and cuts that give you full range of motion. Plus, looking good while you sweat just hits different. Whether you're heading to the squat rack or hitting the trails, your wardrobe should match the energy you’re bringing to your workout goals.
For those making the most of their gym memberships, it might be time to tidy up the essentials: think supportive tees, shorts that move with you, and flat-soled shoes for those heavy lifts. Meanwhile, runners need gear that battles the elements — sleek, aerodynamic designs that keep the wind out and the heat in. Even if you’re ditching the gym altogether and going it alone, upgrading your kit can make all the difference. And let’s be honest, we all want to look as good running errands post-workout as we do during it.
To help you on your way, we’ve rounded up some of the best men’s activewear to keep you styled out this January. From workout tops to winter-ready outerwear, here’s everything you need to kickstart the year in style.
