The Core Long Sleeve by Forme® is your go-to long sleeve smart self-correcting posture tee with all the health 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 a dual layer intellgent construct using muscle memory 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, without restricting movement.
Unlike compression wear or taping forcing posture into place, Forme brand’s approach works with the body’s neuromuscular system, supporting the muscles responsible for upright alignment and back health, so posture improves through use, not effort.
Developed by an orthopedic surgeon for his mother, who battled late-stage cancer and suffered from poor posture and compressed lungs, Forme® was created to empower people with health, strength, and confidence.
Fit Tip: If you experience pressure under the arms, consider smart tee or layering the Core Long Sleeve over a light tee to ease your transition.
How to Wear Forme®?
Forme® is designed to be worn as part of your everyday routine, at work, while traveling, during workouts, athletics, rehab, post surgery, or even while sleeping.
✔ Begin by wearing for a few hours per day during the first 1–2 weeks to allow the body to gradually adapt to changes in muscle activation and postural alignment.
✔ An immediate improvement in posture may be observed upon wear, without conscious effort, due to the smart apparel's integrated alignment technology.
✔ Mild muscle soreness may occur within 1–2 days of initial use, similar to muscle adaptation or training fatigue. If discomfort occurs, discontinue use for 1–2 days before resuming wear.
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.
✔ HSA/FSA Eligible: To use HSA/FSA funds, please check out with Flex. Receipts cannot be issued post-purchase.
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.

Reviews
Shirt is comfy and is
"Shirt is comfy and is helping my mini hunch back go away."
"I have purchased two of these. They do as advertised, and i find myself paying more attention to my posture. I can certainly afford what i consider an over-priced piece of exercise kit. But I wonder about the long term success of the vendor given this price point."
Don't be afraid to purchase as a woman!
"This is a men's shirt, however, I think it's super flattering for women with larger chests. The scoop neck is perfect, and when I wore this I felt so much relief. Will be purchasing more."
I find the Forme well
"I find the Forme well fitting and comfortable for both daily and exercise wear. I am disappointed in that I ordered two core and two ace and now I see the ace tees are 30% off. Would have been nice to have received that offer from your staff verses the 15% that was offered."
"Comfortable and definitely works."
The material feels light but supportive
"I’ve worn this Core Long Sleeve for a few weeks now, and my upper back pain has noticeably improved. The material feels light but supportive, and I appreciate how subtle the posture correction feels throughout the day."
The material is next-level soft
"The material is next-level soft but still holds you in all the right ways. I wear this almost daily for working from home and it’s improved my posture more than I realized."
Perfect for flights and long drives
"I wore this on a recent cross-country flight, and my posture felt better than usual. Long sleeves make it feel more like a comfy base layer than a ‘medical’ piece. Great travel companion."
You’d never guess it’s a recovery tool.
"It fits right into my usual style. The clean lines and soft texture make it easy to dress up or down. You’d never guess it’s a recovery tool."
Might get a second one soon.
"Didn’t expect this level of breathability in a supportive top. I’ve worn it in warm weather and still felt comfortable. Might get a second one soon."
