Aspen FLX 639 LSO Back Brace

$288.00

The most supportive model in Aspen's FLX line of inelastic braces, the FLX 639 LSO offers a conservative treatment option for lower back pain with extended coverage and lateral support. Structural improvements enhance stability while keeping a sleek, breathable profile, and the one-size-adjustable design delivers targeted compression and stability to aid pain relief.

Is this the right one for you?

Choose this if the pain is muscular or postural — everyday lower back pain, strain or fatigue, with no disc or joint diagnosis.

Been told it is a disc? Sporlastic VERTEBRADYN AKTIV Back Brace is built for disc protrusion and prolapse.

Been told it is the facet joints? Bauerfeind LumboLoc Back Brace relieves those small spinal joints specifically.

Pain lower down, across your pelvis or hips? medi Lumbamed Sacro Pelvic Support targets the joints where your spine meets your pelvis.

This is a medical-grade orthopaedic brace that incorporates rigid structural support. Braces and orthoses built with rigid components are usually covered under Canadian extended health benefit plans (e.g. Sun Life, Manulife, Great-West Life, Blue Cross, Green Shield Canada) when accompanied by a valid prescription from your physician or nurse practitioner. It may also qualify as an eligible medical expense under the CRA's Medical Expense Tax Credit. We're happy to provide a pre-approval form for your insurance provider — just contact us before ordering. Coverage details, annual limits, and prescription requirements vary by plan, so please confirm your specific benefits with your provider and keep your prescription and itemized receipt for your claim.

One size adjustable — the overlapping closure adapts the brace across four internal sizing positions (waists of roughly 28 to 54 in).
