Herm Sprenger's new patent pending Neck-Tech Sport collar has been getting great reviews and our customers have been asking for it, so here it is. Measuring 19" or 24" in length with size being adjustable beyond that by easily removing or adding links as needed. Each link and new ClicLock buckle are stainless steel for maximum durability, even in wet or salt water conditions. The slider in the buckle, made from high-quality UV and salt-water proof plastic components, protects the push button from unintended release.
