The Stitching is Not Good

It will fit good and also gives proper support but the stitching very bad. The Velcro came off within 2 weeks of use.

We appreciate you taking the time out to write to us. I apologise for your unpleasant experience with our back support. The functioning of the velcro could be a function of 2 things

Size - Choosing a smaller size will cause undue stretching of fabric as well as stitches / velcro (not to mention discomfort to the user). Please measure the diameter about 5cm above your hip and follow the below mapping for the right size.

65 - 85 cms : 1

86 - 115 cms : 2

116 - 140 cms : 3

Manufacturing quality : We work hard to ensure are products are designed for the intended use along with thorough testing. If you believe the issue is due to to a manufacturing defect / quality of the velcro itself, do reach out to the nearest store (if purchased at a store) or raise a return request your account on (if purchased online). We would love to look into the issue and provide a solution

As always, we hope we are able to help you with your issue and look forward to the opportunity to serve you in the future. Do write to us on for any other feedback

Why wear this back brace?

This back support plays a preventative role​. It compresses the lower back to help you maintain good posture. This back brace is made from thin, airy fabric to make it discreet and easy to slip under your clothes, and to keep your back dry.

Why is good posture important?

Better awareness of the position of your hips and spine improves your posture and will reduce the risk of back pain. With this back brace, patients will be more aware of their own bodies and can play sport (basketball, football, handball, tennis, badminton, running, trail running, gymnastics, judo) under the best conditions.

Choosing your lumbar brace size

Measure your waist size, to 2" above the hips. Then match the measurement taken with the following size chart: Size 1: 25.6" - 33.5" Size 2: 33.5" - 45.3" Size 3: 45.3" - 55.1"
