My husband and I purchased these belts and a couple of bungee lines for skijoring with our dogs, and now use them for running and hiking as well. They are lightweight, low profile, and extremely comfortable. They’re also super adjustable and stay in place really well when tightened properly. It’s been a game changer for enjoying pulling sports with our dogs! We’ve tried some other brands and this is hands down the best product. Also want to shoutout Neewa for incredible customer service; one of the buckles somehow broke, and Filippo was incredibly helpful in helping us replace it. We’ll definitely be purchasing more products in the future.
