Flagline™ Dog Harness with Handle

lightweight, multi-use dog harness

Color

Selected: Lichen Green

The Flagline Harness is a fast, light, and comfortable body harness with a nimble design that keeps dogs in their flow, from scrambling in the backcountry to conquering everyday obstacles.

A handle and load-dispersing chest/belly panel make for easy lift-and-assist in a minimal design good for all-day wear. High adjustability and easy on/off make the Flagline secure and accessible, especially popular among tripods, deeming it the harness of choice for giving dogs a little boost and a lot of freedom when the path ahead is anything but flat.

    Pug Houdini stays safe in this harness

    I'm so glad my little escape artist stays safe in this harness. That additional strap keeps him secure when we go on walks. I also like how light weight yet high quality the harness is and the color is nice too.

    Flagline for life

    My dog had a flagline for 3 years, and besides losing some color, it's still going strong. My only complaint is that we just got pink/purple color scheme. We need more colors!

    Great harness

    Easy to put on and adjust. Our dog doesn’t seem to mind wearing it at all and it works well on walks.

    Amazing and Cute Colors!

    It was perfect - the sizing was a bit off for my pup but she has weird measurements! It’s a great light weight of the webmaster is too thick.

    No more escaping!

    This harness is great for dogs that like to try to back out and escape on walks. I had a lot of close calls with my husky escaping his old one and this harness has been a game changer. I don’t even have to worry about him getting out now on walks and it’s great!
