Our leashes are made with half inch (0.5") diameter, water resistant MFP polypropylene rope and are available in a variety of colours. Our rope is braided just for us right here in the Maritimes. MFP is incredibly strong, yet light weight and soft. The half inch diameter is nice and chunky and has a great ergonomic hand feel. The leashes all feature a highly reflective tracer for added visibility at night time. Every piece of hardware on these leashes from the lobster leash clips, to the rope clamps, right down to the poo bag holder ring is custom made from marine grade 316 stainless steel which is extremely heavy duty and offers excellent corrosion resistance, even in salt water! All of these awesome features make them perfect for more than just the beach, they will stand up to your city, forest and mountain adventures too!
