Resistance Band Set With Carry Bag - DDL Technology for a far better and more comfortable stretch - Made from highest grade full metal carabiner (61.5 mm x 5 mm) to ensure that will they last forever and will never snap open - Layered construction, not moulded. Info: - Moulded bands are created by pouring liquid latex into a mould and letting it harden. Moulded bands are a weaker band because of what we call the matrix effect. - Layered bands (Like our ones) are formed by bonding multiple layers together with a strong epoxy that is heated. This creates a much stronger matrix bond. If a layered band gets a slight cut along the side of the band, it will not tear easily because there are multiple layers holding it together. If moulded bands get a slight cut, they will tear like a piece of paper because it is all one piece.
