The Ace Long Sleeve by Forme® is a FDA-registered self-correcting posture tee designed for recovery and back health.
Crafted from premium, sweat-wicking fabric and engineered with dual layers of our patented wearable technology, the Power tee delivers a stronger pull to improve posture, reduce pain, and accelerate recovery after high-intensity training.
Trusted by Olympians, professional athletes, and everyday movers, it’s designed to be worn solo or layered, for work, training, travel, or rest.
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 sizing up or layering the Ace 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.
All orders for the Ace Tee Long Sleeve are final sale.
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
Super comfortable and good fit.
"Super comfortable and good fit. Can feel the slight pull to keep shoulders back."
My alignment has improved
"I was going to posture therapy twice a week, but this shirt has reduced the need for constant sessions. It doesn’t replace medical care, but it makes my daily routine more sustainable. My alignment has improved and pain levels are way down. It’s like carrying a physical therapist on my shoulders."
I’ll be grabbing another one for rotation.
"I put this on after a tough basketball game, and my shoulders just opened up. The compression and pull feel supportive but never restrictive. I’ve noticed my breathing is deeper, and I don’t hunch forward as much when I’m tired. The quality of the fabric is top-notch, too—handles sweat well. I’ll be grabbing another one for rotation."
Game-Changer for Travel
"I wore this on a cross-country flight and was amazed at how much better I felt getting off the plane. My back wasn’t stiff, and my posture stayed steady even after sitting for hours. The long sleeve is great because I didn’t get cold on the flight either. It’s become my go-to travel top, especially with the Ergo Short."
Noticeable Recovery Boost
"After lifting, I usually feel tight across my shoulders and traps. This shirt helps me open up and feel less compressed after training sessions. The fit is snug but comfortable, and I did follow the tip to size up for layering. Recovery has been smoother, and I’m not slouching like before. Honestly, I didn’t expect a shirt to make such a difference, but it really does."
Helps Me Stay Upright All Day
"I’ve struggled with rounded shoulders for years, and this long sleeve makes me instantly aware of my posture without restricting me. The pull across the back feels subtle yet keeps me aligned even when I’m at my desk for hours. I’ve worn it to the gym and on flights—it adapts so well. The fabric breathes nicely, and it never feels heavy. Easily one of the best investments I’ve made for my body."
I don’t hunch over as much
"I was skeptical at first, but the Ace Long Sleeve has completely changed how my shoulders feel during lifting. I don’t hunch over as much, and I recover faster between sessions. The fabric is light enough that I don’t feel weighed down, even when I’m sweating hard. It’s also nice to wear casually because it doesn’t look like “medical gear. ” This has become part of my weekly rotation without question."
Definitely a game-changer for office wear.
"I spend most of my day at a desk, and this long sleeve makes a noticeable difference. My shoulders feel more open, and my back pain has decreased. The fabric is breathable, and I can wear it under jackets or alone without feeling restricted. Definitely a game-changer for office wear."
It’s like following medical advice
"My orthopedist recommended Forme after I complained about constant shoulder rounding from working out. He said alignment would help prevent future joint issues. I started with the Ace Long Sleeve and could feel the correction immediately. It’s like following medical advice without even having to think about it."
Definitely sticking with this for my gym sessions.
"I threw this on during weight training, and I could feel my chest stay more open while pressing. My shoulders didn’t round forward, which usually happens under fatigue. The shirt’s pull feels like a coach correcting you, but in the most natural way. I’ve noticed my recovery feels faster, too. Definitely sticking with this for my gym sessions."
Q&A
- What’s the difference between a core and an ace shirt?
- Hi Steve. The notable difference between the two items is that the Core tee is made with modal, which is a natural fiber that feels more like cotton. The Ace tee is a lighter fabric and tends to feel more breathable during highly active situations. However, both are great at posture correction and improvement in a variety of situations.
