The Extreme Biothane Leash is top of the line!  It is constructed with 5/8" Biothane Coated Webbing (rated at 1,000 lbs), and a Kong Frog connector (rated at over 2,000 lbs). 

These leashes are incredibly strong, light weight and easy to maintain.  They can get wet, muddy, and dirty with no issues.  Just wipe clean and you're good to go!  The Kong Frog connector is insanely strong, light weight, and will snap closed on contact with your collar's d-ring.  

Pro Tip: Match your leash color with your font color on your personalized collar for a combo that will really pop!
