The 'snap' fasteners are all made from acetal which is non brittle and doesn't absorb moisture, making them tougher than their nylon counterparts.
We also use stamped Nickel plated D's - far more reliable and stronger than the widely used welded Ds you often see on dog collars.
Made from our soft Tactile Webbing - 16mm width.
Machine washable at 40 degrees.
