Breakthrough innovation. Powered by Tommie Copper®. Made to fit movement, with a low-profile, forming fit that turns everyday steps and simple sessions into more purposeful work, without bulk. Women-first fit: two adjustable straps + elastic sides for a secure, confident wear across many body types. Fixed, Forming stability: CoreFusion™ gel shapes to you for a steadier, quieter feel than foam-lined or bare-pocket vests. Plate systems are flexible, but they can introduce time friction and micro-shifts between plates and pockets. This vest uses a fixed, evenly distributed load to smooth pressure points and help keep the weight centered, so sessions stay simple and consistent. Even distribution: second support strap helps keep weight centered; less shifting, more control. Built-in cooling: patented BetterIce™ layer is a sealed, flexible gel layer that delivers an immediate, even cool sensation during and after activity (comfort only.) Simple progression: fixed loads plus a slow and stready increase in time, terrain, and frequency can dial up challenge. Designed for comfort & safety Soft, flexible construction with adjustable straps and elastic sides for a secure fit. Made with breathable 87% nylon / 13% spandex, evenly distributed weight for comfort, and high-reflective trim for visibility in low-light conditions.
