Aluminum waistband is moldable to each patient’s unique torso shape and prevents anterior migration that is common with shoulder braces. The ARC® 2.0 universal sling design folds to fit every patient with one brace – right or left, football player or gymnast. The ARC® 2.0 features 2.0 material for maximum breathability and comfort. 2.0 material moves moisture away from the skin to another layer of fabric for quick evaporation.
