● ClimaLite is a clothing technology that Adidas developed for buyers who did not want to feel as if they were wearing a heavy, bulky item of clothing. This line is made up of incredibly thin, soft, and breathable materials. Many of the ClimaLite items that Adidas offers are undergarments, since it promotes comfort while still providing wearers with the amount of support they need.
Search "Adidas Boxer" for all the products. There are Climacool and Climalite available but not all of them are active for the Buy One Get One 50% promotion.
