Hyperice Normatec Arm Attachments are supplied as a pair for compatible Normatec compression systems. Each arm attachment uses five overlapping zones running from the hand through the forearm, elbow and upper arm to the shoulder. An elastic band with an adjustable buckle helps secure the fit, and the pair is compatible with Normatec 3, Normatec 2.0 and Normatec 2.0 Pro systems. The package does not include a Normatec control unit, so these attachments do not operate as a standalone compression system. They are intended for owners who already have a compatible Normatec controller and want to add arm coverage to the same platform. Because both arm attachments are included, the SKU should be represented as a pair rather than as a single sleeve. Powered pressure selection and session control remain functions of the connected Normatec system, while the five-zone construction is built into each arm attachment.
