Flagline™ Dog Harness with Handle

lightweight, multi-use dog harness

Color

Selected: Sage 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.

    Very happy with the purchase of these for my two dogs.

    This is a great starter harness for my new pup to get used to. The three different leash loops are great for not pulling and pulling. Lol, I know that's weird to say, but the loop on the very back is great for her to drag a wagon behind her. While the loop on the chest keeps her from pulling. I got this harness for my 11 year old pup as well and the handle is great for hold her up when she is unsteady on her feet.

    Still great!

    This is the second flagline harness I’ve purchased for my husky. The first held up to more than two years of daily use and when it was time to replace it, we got another because the design is easy to get him in and out of but it’s secure when it’s on. We love the handle to help maneuver both on busy city streets and in tough spots on hiking trails. It does compress his fur a bit so we have to watch out for mats, but a small tradeoff for the other features.

    Fits my dachshund perfectly

    I can finally stop shopping for the right harness. I have tried four different brands trying to find one that fits my dachshund and I’ve finally found one that fits him perfectly with all of its adjustments. The material is great because it dries much faster than some of his others, which is necessary since his under carriage is so low to the ground and he gets soaked in wet grass. Expensive, but well worth it, fit is amazing and is high quality material and stitching.
