Jaybird & Mais 40 Economy Non-Elastic Athletic Tape is a blend of polyester and cotton fibers which makes an economical, but very strong high tensile strength rigid athletic adhesive tape. Used for applications such as ankle and wrist taping where the application goal is to reduce range of motion while creating joint support at the same time. The strapping tape comes with a serrated edge cut as standard and is hand tearable (the product also tears lengthwise for additional versatility). Jaybird #40 is un-bleached and comes coated with a 100% latex-free hypo-allergenic adhesive.
Please see Jaybird's Taping Techniques reference for the proper way to tape preventative and post-injury applications.
