The NelMed Calf Urinary Leg Bag Support comfortably secures a leg bag discreetly under clothing. The soft, wide straps help reduce tourniquet effect, a restriction of oxygenated blood to the tissues, often caused by thin leg bag straps. The latex-free elastic straps are two inches wide with large buttons that will fasten to most urinary leg bags. One size fits most. Upper calf strap fits up to 17 inches, Lower calf strap fits up to 14 inches.
