The Aspen Evergreen 637 is a medical-grade LSO that provides trunk stability and compression around the lumbar spine for pain relief. The Evergreen 637 LSO includes a rear panel that extends from the the T9 vertebrae down to the sacrococcygeal junction, as well as, an anterior abdominal panel stitched into the front of the back brace. Additional side panels provide greater rigidity and flexion/extension/side bending motion restriction. The brace is made out of durable mesh liner fabric for comfort, and features two separate draw strings to customize the amount of compression for your torso. Large nylon thumb loops allow the user to generate a 4:1 mechanical advantage in the rear pulley housing with ease.

It's ideally suited for multiple level spinal injuries such as lumbar disc herniations, sciatica, and recovery from mild to moderate spine procedures.

Love my new brace
I'm enjoying this Aspen back brace 637. It supports my discs and it's much better than my last one which both heavy and bulky.

Great support
My first 637 brace finally wore out after 5 years - bought this replacement and it arrived in a sealed manufacturer's bag, perfectly new. This is the only LSO that works for me.

This brace fit my husband
My husband swears by his brace - he ended up purchasing the extension panels to make it fit and it's perfect for him. He says it's the first brace that fit right in the last 30 years he's had back issues.

Helping my bad back
The support from this is helping my old L4- 5 disc injury. The brace keeps my back from bending which has always aggravated the pain down my leg. Expensive but well worth it.
