Great quality long line!

I have had this long line for just over a month and use it nearly every day. It's comfortable, easy to clean, and looks great! I'm sure I will order another but I will probably get the regular snap next time, the carabiner is not the easiest to use. That being said if it were the only option I would still reorder! Biothane is worth the investment!

So glad you are enjoying your long line! The BioThane is so easy to care of! Thank you Trina!

Love high tail hikes!

100% recommend them! After ordering a 30 ft leash, we knew we needed more. We currently have the a 10ft, 15ft, and 30ft because these are fantastic. So durable, easy to handle + clean, customizable, and pretty!

Lucia, we love hearing how much you love our long lines! Thank you!

Favorite leashes

Our trainer recommended High Tails Hike leashes many months ago, and we first got an 8ft convertible for our hikes. We’ve since gotten different leashes for all our different activities (customization is wonderful!). Love that they are waterproof and easy to clean.
