Base layers & Thermal Clothing

Once you discover the sleek lines of adidas base layers and thermal clothing nothing will stop you from smashing your winter training goals. Our breathable thermals are perfect for keeping your muscles warm during outdoor HIIT sessions and resistance training in the park. As more of us enjoy the benefits of exercising outdoors, high-performance thermal clothing that stays put while allowing free movement is a worthwhile investment. Our supportive designs let you comfortably stretch and lunge and move your arms overhead without any gaping or rising up. The sweat-wicking technical fabric of our base layers keeps you warm but prevents uncomfortable overheating. With compression, slim and regular fitting options and ingenious features like reflective detailing and handily positioned pockets, you’ll find pieces to suit your exercise plan. With superior fabric technologies and streamlined designs, cold weather needn’t be a problem.

Stay warm and cosy when winter hits and the temperatures drop with the versatile range of adidas base layers. Choose from a wide array of thermal clothing including thermal leggings for men and women in full length, three quarters and shorts. Consider completing your cold weather protection with a thermal top, choosing between short- and long-sleeved designs for both men and women. adidas base layers are available in a selection of different fits to suit your needs and preferences. Opt for regular fit which moves gently with you, slim fit which offers light compression, or a compression fit which offers optimal support to your muscles by regulating body temperature and limiting lactic acid build up during your entire exercise session, including warm up and cool down.


The adidas selection of base layers and thermal clothing has been designed using advanced technologies to keep you warm and active when cold weather threatens to spoil your exercise plans. These include the use of technical insulating fabric characterised by closely-woven fibres that allow it to trap your body heat and keep you naturally warm. Sweat wicking thermal wear is built using a lightweight modern fabric that keeps your skin surface dry and comfortable when exercising in cold weather. Ingenious mesh panels add breathability and – for an extra responsive feeling – cutting-edge RHEON technology is incorporated into our compression fabrics to give adidas base layers unrestricted yet supported movement.


In addition to keeping you warm in cold weather, hard-working base layers by adidas will keep you protected through thoughtful and detailed design features. The use of flatlock stitching in our seamless thermals reduces chafing and delivers zero-distraction comfort when you’re working out or heading out into the cold. Several of our winter thermals also feature a shaped hem to give good coverage as you move. And for protection from the harmful, winter sun’s rays, choose a style equipped with UV protection to ensure safety for your skin.
