A braided nylon, Dark Grey Perlon NATO Style Watch Strap with stainless steel hardware. Included are two keepers (one fixed metal, one free Perlon). The Perlon material is shipped directly from Europe which lends to the authenticity. This strap has an extremely lightweight, durable design! There is a heat seal which has been carefully applied to the end in order to prevent fraying. NOTE: Due to the characteristic elasticity of Perlon material, there may be some variability in length per strap with a difference of up to 5mm.
