The Core Long Sleeve by Forme® is your go-to long sleeve tee—with all the posture-correcting benefits you love, now with extra coverage and support. Perfect for everyday wear, lounging, travel, or sleep, it combines comfort, style, and effective alignment correction.

Made from the same ultra-soft, breathable, and eco-friendly Tencel™ fabric as our signature Core Tee, this FDA-registered tee features dual layers of patented posture technology for a stronger, more supportive fit. It gently engages your muscles to keep your shoulders back and your spine aligned—helping to ease neck, back, and shoulder pain linked to spinal issues, without restricting movement.

Developed by an orthopedic surgeon for his mother, who suffered from poor posture and compressed lungs, Forme® transforms your body by building a foundation that enables you to perform, think, and live at your highest potential.

Fit Tip: If you experience pressure under the arms, consider sizing up or layering the Core Long Sleeve over a light tee to ease your transition.

Full Body Alignment: Pair with the Ergo Short and Arch Booster Sock or Ankle Guard Sock.

Advanced Support: Visit our Health Benefits page for guidance on musculoskeletal conditions.

Forme®'s wire and sensor free wearables use a patented construct of lightweight, multidirectional tensile materials to engage muscle memory for biofeedback and instant proprioception. Our patented technology enables the body to relearn its best alignment spatial sense to keep your back straight, reduce pain and stiffness, and elevate your physical function.

Before & After

What people are saying

“Formewear is incredible in that it helps you to activate your back and posterior muscles passively. It dynamizes the back muscles, allowing the back to "breathe", gently giving you a constant reminder to extend and flex your spine in an unrestricted way, and that is how you can avoid muscle spasms and the most common causes of back pain. Your spine is the backbone that protects all your vital organs and Formewear can help you to be the most efficient and productive, supporting your vital organs and providing room and ability to function everyday through good posture.”

Hyun Bae, MD

Orthopedic Spine Surgeon, Cedars-Sinai Medical Center

Director of LA Spine Institute

“Posture is everything! I see it everyday in my practice from my professional athletes to my everyday athletes of life. Formewear fixes the thoracic then solves the lower back, neck and shoulder issues automatically. On top of this, the benefits for breathing and oxygenation through the opening of the rib cage are undeniable!”

Fabrice Gautier

“I wear this when I see patients and when I perform surgeries, it has been a life saver to reduce shoulder and back pain, while letting me function at my best.”

Freddie Fu, MD

“This shirt changed my posture immediately and I can feel a difference right away. It is also really comfortable. Additionally, many athletes have felt immediate improvement in posture, recovery and shoulder rehabilitation.”

Answorth Allen, MD
