- Some like 'em high! In recent years a lot of 'high-profile' athletes have asked us to create an Aireator that rides taller. Our knitting engineers came back with the HIGH TOP - two heights, a 5 or 4 inch tall single-layer cuff. On the Aireator, it's a match made in heaven. Good looking and super-light. Start wearing the Aireator HIGH TOP and it might become the favorite in your drawer. Made from CoolMax EcoMade or from the finest Merino wool.
