Once a staple in stores like Barneys and Bloomingdale’s, you can now purchase Isaora’s performance gear exclusively online, which just goes to show you how confident the brand is in its high-functioning jackets, shirts, and sweats. Details like no-sew construction (seams are bonded together with pressure and heat) and tech-laden stretch materials allow for frictionless movement, while three-layer waterproof nylon (check it out in the rainwear collection) combats moisture while also allowing your skin to breath.
