The size range is not helpful and is not directly related to waiste size. As it's important to significantly overlap both ends go up one size. Mine is unusable as it's too small for a 32"waiste.

Hello Michael,

thanks for taking the time to leave a review on the Soft 300 Lumbar Brace.

I'm sorry to hear about your not satisfactory experience with our supports sizing unfortunately, being a international company, we had to come up with a sizing system that could work for all of our customers so, for all of our supports, there are specific measurements that need to be taken to understand which size would fit properly.

Anyway, I can suggest you to take the item with the receipt to the closest Decathlon store where you can exchange it for the right size or get a full refund.

Why wear this back brace?

Wearing this back support, with its boning at the back, may be recommended if you have lower back pain/lumbago, or if you are unsure about how your back will cope when getting back into sport (basketball, soccer, handball, tennis, running, trail running, gymnastics, judo). It is easy to put on and adjust, with a shape designed to fit your back and keep you comfy. Essential for a home gym.

What is the difference between lower back pain and lumbago?

Lower back pain and lumbago are actually the same thing: back pain in the lumbar region. This pain can be caused by different things, from fractures to deformities and slipped discs. The pain will only disappear if the cause is treated. Wearing a back brace can help reduce pain thanks to its heating action, compression, and the restricted movement.

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”
