Three layers of materials make up this lumbar belt: terry-towelling with microcapsules, polyamide, and perforated neoprene. The terry-towelling layer is designed to neutralize colors as it is in contact with the skin. The polymade that makes up the finishing layer is made of beige or navy blue. These materials allow breathability with the lumbar belt when used for cross ligaments, as opposed to other orthosis in polychloroprene. It’s available in four sizes: S, M, L, and XL.
