Posture Brace XXL Adjustable with Wide Shoulder Harness, Size Guide Based on Weight 35 to 95 kg, Polyester, Black or Gray | Sansoti

Four sizes, with sizing based on weight rather than guesswork

With a posture brace, the fit determines how well it works: too loose and you won’t feel anything; too tight and you won’t last an hour. That’s why the sizing advice here is based specifically on body weight: M for 35-50 kg, L for 47-65 kg, XL for 62-85 kg and XXL for 82-95 kg. XXL is the largest size and fits up to 95 kg. All sizes feature a wide shoulder harness with hook-and-loop fasteners, side straps with a loop system and a universally adjustable design, so there’s room to adjust even within each size. Material: polyester with a soft shell and flexible structure, in black or gray.

Sizes and specifications

• XXL up to 95 kg: the largest size, with the same wide shoulder harness as the smaller versions.
• Weight-based sizing advice: M 35-50 kg, L 47-65 kg, XL 62-85 kg, XXL 82-95 kg — a specific number instead of guessing between S/M/L.
• Universally adjustable: the loop system on the side straps provides extra adjustment within each size.
• Wide shoulder harness with hook-and-loop fasteners: wide straps distribute pressure so they don’t dig in when worn for longer periods.
• Soft shell with a flexible structure: supports the upper back without restricting your movement.
• Polyester: thin enough to wear under clothing; hand washing is recommended to protect the hook-and-loop fasteners.
• Black or gray: two colors, suitable from age thirteen.

Choosing the right size

The size chart is based on body weight, and the ranges deliberately overlap: at 48 kg, you can choose M or L; at 63 kg, L or XL. In that case, choose the smaller size if you have a slim build and the larger one if you have broader shoulders, because the brace fits around your torso, not your waist. If you weigh over 95 kg, this model is outside the stated range. After putting it on, adjust the side straps until you feel the feedback across your upper back while still being able to breathe freely and stretch your arms forward. Gradually increase how long you wear it instead of wearing it all day from the start. Hand wash the brace, as machine washing will ruin the hook-and-loop fasteners. If you have persistent back or shoulder problems, it’s advisable to consult your doctor or physiotherapist.
