Urocare - Lower Leg Fabric Leg Bag Holder has a pocket that your leg bag slips into. The breathable material is a blend of 95% cotton and 5% lycra. This product eliminates contact between your skin and the urine bag and is an alternative to leg bag straps. It can be worn on the inner or outer side of the calf. Be sure to measure the circumference of your leg before selecting your size. This urinary leg bag holder is compatible with reusable latex or disposable vinyl leg bags.
