    Great experience

    Pleasantly surprised by quality of order. Heartfelt thank you.
    I am able to carry doge as she is senior and cannot walk long. Now it's possible for her to join me on longer trails.

    Great Pack!

    I've been looking for a backpack that could not only hold my dog but also hold my gear. I bought the small pack for my 15 lb dog and it fits perfectly. I'm glad I found this pack because it allows me to bring my 13 year old dog on hikes giving me the option to carry him when he gets tired.

    Exceeded My Expectations

    I purchased this carrier for our camping trip to Colorado. We have a pug and at times he gets tuckered out quick, so we wanted a way to keep him with us on our hikes. Especially seeing where we live the elevations is 610 ft and where were were camping was 9,000 ft, having a comfy carrier was that much more important. I’m SO impressed!! I had my 28 pound dog strapped to my back for the entire hike, aside from potty/water/snack breaks and both Fenton and I were comfortable the entire time! (I know this because on several occasions he fell asleep to the point of snoring). When he was awake, he was smiling like crazy! Even fellow hikers commented on that! I’m so very happy with this purchase! On top of that, the customer service is top notch. I also ordered the sunglasses and a custom name patch. Unfortunately (?) I received the wrong one (Poncho) but was quickly sent the correct one (Fenton). That being said, we decided that “Poncho” is now Fentons trail name. ;). Thank you so much for this amazing carrier and accessories!!!

    Great for dog and great for day pack

    Got the chance to try our Knavigate on a Tuesday afternoon in the mountains. George was a little wiggly getting in, as he had no idea what we were trying to accomplish. Once he was in and on my back, it was a breeze! He didn't seem fidgety or uncomfortable at all and stayed on my back for well over a mile. He can usually hold his own just fine, even on longer hikes, so I've mostly been using it as a day pack. The small size really has a lot of room in the bottom zipper pocket, and I've stashed jackets and water bottles in the top when the dog's not in it. I think this will keep bringing adventure to our little family as George continues to get older. Great investment!
