Description
Overview
The Lumbar Support L4 Belt 900 is Decathlon’s black lower-back belt, rated level 4 out of 5 on Decathlon’s support scale (the “L4” in the name). Soft rear reinforcements sit over the central lower back, and an elasticated belt with wide adjustable straps sets how firmly it sits.
Decathlon designs it to be worn during workouts and, when needed, during gentler activity such as walking. It comes in three sizes chosen by waist circumference, and Decathlon advises wearing it snug against the skin.
