These collars are made from a material called biothane which is a woven nylon and polyurethane. Plus there is a 3M reflective tape embedded onto the collar, showing up as reflective!
This collar is extremely durable, won't crack, break, split, chip, or stretch out, and remains soft and pliable, even in extreme weather conditions. These collars are fun and functional for many sized dogs and different hair types. They are very versatile and bright so I like them as a safety collar.
With this collar, one size fits most. These are simple collars that don't do a lot in the comfort department.
