    I just got the order and I'm very happy. I can't wait to try it in action.

    Best thing ever

    These bags are quite literally the best thing ever invented. My pitbull is going through heartworm treatment and can’t do strenuous exercise but she loves being carried on hikes. All of my friends want one of these bags now.

    Works perfectly for our 20 lb golden puppy. Great support for him, snug and comfortable for the carrier.


    Lucy and I love our sport sack. We did a short ride to give it a try and Lucy was in heaven! We can’t wait for some warmer weather so we can take some long rides!

    Love the Knavigate!

    The waist belt is a game changer. The Knavigate is a lighter option with a waist belt and works perfect for our corgis.
    We get a Medium as they are smaller/thinner corgis and it’s perfect.
