Amazing pack!

We use this pack every weekend on our fishing trips and remote hikes. Previously I have used their approach bags but they were always too big for our liking. We've got a 65# lean and tall husky so we went with the medium. It fits perfect with a little room in the girth if needed. The pack washes very well - it gets washed after every venture.

Great but wish it had water bottles for bigger dogs.

So far this pack is exactly what i was looking for. It took a bit to get my dog fitted to where it wasnt too tight or too loose whether he was walking, sitting or laying down. I use this as a service dog pack so fit was vital as well as for it to be easy on/off and easy to clip. I sewed on some velcro and added some patches that I had for him. So far the pack is great! Holds his snacks, drool rags, fold up doggie bowl, etc. Only complaint I have is that the water bottles are too small for large/giant breed dogs if they were to go on hikes. He will eventually go on hikes and I will have to carry extra water because at 130 lbs he drinks both water bottles full of water. But besides the small water bottles, the pack is perfect and exactly what I was looking for. Paired up with the brush guard the pack gives my big boy enough support underneath and doesnt dig in anywhere or rub him armpits!

Best Day Hike Pack

I love this pack! So great and versatile. We use it on day hikes all the time. The water bladders are great for training the dogs to hold more weight but really the best part is that these little packs can hold the **** bags.

Best dog purchase

Our dog LOVES this pack. She is a 65lb german shepherd mix, and knows we are going to go on a long walk or head out hiking when we take it out. It stays on perfectly and it's so convenient not having to pull out our water to give to her. We received SO many compliments and questions about it on our last 7 mile hike, so hopefully more people will purchase it soon! Totally worth every penny.
