Description
No need for armor to stand tall. This lightweight posture corrector focuses on the essentials: two padded straps and a perforated back panel that gently pull your shoulders back as soon as they start to slump. It slips under a shirt or sweater and goes unnoticed, whether at the office or at home.
What it actually does
- Shoulder reminder — as soon as you slouch, the tension from the straps alerts you.
- Lightweight and discreet — nothing on the stomach or chest: it can be worn under clothing.
- Perforated back panel — vents allow air to circulate between the shoulder blades.
- Padded straps — to distribute pressure under the armpits.
- Hook-and-loop adjustment — you can set the tension yourself in seconds.

Good to know
A posture corrector is a reminder, not a treatment: it does not cure back pain or spinal deviations (scoliosis, kyphosis) and does not replace strengthening your back muscles. Wear it for 20 to 30 minutes a day at first, then up to 1 to 2 hours; do not wear it while sleeping or all day long, and loosen it if you feel tingling in your arms. It is not recommended, unless advised by a doctor, in case of recent injury or surgery to the back, shoulders, or ribs, spinal conditions, pregnancy, or skin problems in the contact areas. Not suitable for children.

Frequently Asked Questions
How does this posture corrector work?
Its two straps form a “figure eight” around your shoulders. As soon as you slouch, they tighten and gently draw your shoulders back. It's a posture reminder: it helps you become aware of your position, it doesn't hold your back up for you.
How do I choose my size?
Measure your chest under the armpits: S 70–85 cm, M 85–105 cm, L 95–115 cm, XL 105–120 cm. If you're between two sizes, take the larger one: the hook-and-loop straps let you tighten it.
How long should I wear it?
Start with 20 to 30 minutes a day, then gradually increase to 1 to 2 hours, preferably at the times when your posture is at its worst (screen work, driving, household chores). Do not wear it all day or while sleeping: your muscles need to keep working.
Is it really discreet under clothing?
Yes: it has no belt or strap across the stomach or chest. From the front, all you see are two straps around the shoulders, which disappear under a shirt, jumper or jacket. Wear it over a thin T-shirt, never directly against the skin.
