Size Guide
Measurements are shown in their listed units. To convert inches to centimetres, multiply by 2.54. To convert centimetres to inches, divide by 2.54.
Clothing & cooling vests
The Fan Cooling Vest is available in M, L, XL, 2XL, 3XL and 4XL. Detailed garment measurements are not currently available, so fit cannot be confirmed from size labels alone.
Do not assume the same letter size fits identically across different products or brands.
Knee supports
The following ranges are listed for the Knee Brace with Polycentric Hinges only. The measuring point is not specified in the saved product information; confirm the manufacturer’s measuring method before selecting.
| Size | Listed leg circumference |
|---|---|
| L | 38–46 cm |
| XL | 45–56 cm |
These ranges do not apply to the Sports Knee Brace. That product lists L, XL and XXL without verified measurement ranges.
Follow the supplied fitting instructions and do not restrict circulation.
Posture & back supports
These chest ranges are listed for the Posture Corrector Brace only.
| Size | Listed chest range |
|---|---|
| M | 28–38 inches |
| L | 38–48 inches |
Confirm the manufacturer’s measuring method. The ranges overlap at 38 inches, so check the correct choice at that boundary.
The Inflatable Lumbar Support Belt lists XL and XXL, but verified waist ranges are not currently available. Other back-support and therapy belts need their own fitting instructions; do not reuse this chest chart.
Rings, bracelets & watches
Check the individual product’s fit notes. Where internal circumference or wrist-fit ranges are missing, we cannot confirm fit from a product photograph or size label.
The Smart Health Ring uses numbered labels 17#, 20# and 22# depending on finish. These are not verified UK, US or EU conversions.
The Charging Cable Bracelet lists cable lengths of 20 cm and 22.5 cm. These are not verified internal wrist circumferences.
Pet harnesses
The Reflective Pet Harness & Leash Set lists XXXS through L with weight bands. Weight alone does not establish fit. Verified chest and neck ranges are not currently available.
Use the manufacturer’s chart and fitting method when available. Check that the harness is comfortable and secure before every walk.
Baby walking harnesses
The Baby Walking Harness Belt is described as adjustable, but verified chest ranges are not currently available. An age range is not a substitute for checking fit and developmental suitability.
Follow the supplied fitting instructions. Do not lift or suspend a child by the harness, and supervise continuously.
