The standard 20mm high quality silicon strap for the new Willard (new 6105-8110). A totally new look, without the waved form that is for stretching the strap. It has a steel tube inside to fortify the push pin hole. The strap is not as soft as the thick new Turtle strap, but it wears really comfortable without being a dust collector. It tapers from 20mm between the lugs to 18mm at the buckle. This black variant is also used for the new 62MAS model (SPB147).
