The Men's Energy Series BioCeramic X-Form Posture Support Long Sleeve Compression Top- Recovery + Endurance (Au8x) was specifically designed for the high endurance athlete. The bioceramic fabric has been engineered to provide a proprietary fabric that is infused with natural compounds that emit far-infrared therapy. Far-infrared compounds include: oxides of zirconium, aluminum, zinc, titanium and antimony. Combined, these elements are known to help improve circulation, repair and regenerate overworked tissues, muscles and nerves, reduce inflammation and decrease pain. This Long Sleeve Bioceramic Compression Top focuses compression of the wrist to the top of the torso, allowing superior range of upper arm motion and also eliminating core restriction. The Biomechanical X-Form design reinforces posterior muscles, and also combats fatigue by promoting good posture while in motion. The Biomechanical X-Form is constructed with a 0.3 mm NeoSkin that reaches from the middle back to across the shoulders. There is an added inner-fabric lining that has been incorporated into the piece for additional comfort and support.
