Menswear essentials brand Mack Weldon has just announced its first line into activewear. Launching through its online site and Equinox locations, the brand has just launched AIRKNITx.

The new series includes a variety of basics including crew neck shirts, socks, boxer briefs, and more. Priced approximately ranging from 24 to 42 dollars, the line was developed from innovative fabrics mills as well as manufacturers. The launch includes apparel composed of a unique microfiber blend that infuse the brand’s signature design approach. This includes a flyless pouch for support, anti-bacterial technology, a high-stretch microfiber zone, and more. "Guys are active all day, every day; so we created a product that is as suited for the boardroom as it is the locker room," Matthew Congdon, vice president of design at Mack Weldon said in a statement. "Our customers want a hybrid product that compliments their active lifestyle."

As the Equinox brand represents a high-performance lifestyle, the Mack Weldon brand goes hand in hand. “As members ourselves, we knew that AIRKNITx and the Mack Weldon brand would align perfectly with the Equinox value proposition,” Brian Berger, founder and chief executive officer of Mack Weldon, said in a statement. Available starting April 20, the apparel is available through as well as in-club shop locations at Equinox.
