The eco-friendly made Core Tee by Forme® is an FDA-registered patented posture activewear that improves your alignment and effectively rehabs neck, back, and shoulder pain commonly associated with poor posture and spinal disorders. Using muscle memory engagement and propiocetion training technology, Forme keeps your shoulders back and down, training your body to stay in alignment. An innovative tech solution for enhanced performance and easier recovery. Core Tee is made from eco-friendly Tencel fabric. The Core Tee is super soft and breathable and can be easily worn as a daily staple with powerful health benefits. Designed by an orthopedic surgeon to help his mother battle poor posture and compressed lungs from cancer, Forme® will transform your whole body alignment, giving you posture that allows you to perform, think, and live at your highest potential. The Core Tee is constructed of different materials and thin layers that are stitched together. The Forme tech inner layer is fused across the shoulder blades, creating an elastic-band sensation which is always contracted. When you put the Core tee on, the fused section wants to remain tight no matter how broad you are across the shoulders. This makes your shoulders pull back to their natural position, teaching your body and diaphragm to open. Some may feel underarm pressure upon first wear. You may size up or consider wearing Forme over a light tee for a few days to allow body adaptation.
