COVERFLEX BANDAGE SIZE 1 Coverflex is comfortable for the wearer and convenient for the carer. This tubular bandage is made permanently elastic by the perfect combination of 91% viscose, 5% polyamide and 4% elastane. Coverflex is a silk-like fabric that is easy to apply without the requirement for additional fixation. It also protects any clothing worn over the bandage because the fabric minimises strike-through. It may be steam sterilised.
