Highly recommend - medium size dog
Super, amazing, the best! Great for our medium sized dog (ESS for reference). It’s sturdy and made from good quality materials. Great for hikes, city and transport. Comfortable and wide shoulder straps for better weight distribution. Highly recommend.

Great Customer Service
I got this as a gift, it was a little small for my dog. So I tried to exchange it on Amazon. It was bought on Black Friday and Amazon told me they would only exchange it if I paid the difference between the sales price and the regular price (~$80) since it wasn't on sale anymore (f#@* you Amazon). I contacted K9 Sport Sac directly and they were happy to do the exchange. The pack seems like it is well constructed and my dog and I are going to have some nice motorcycle trips together :)

Measure first large was perfect for me and my maine coon boy.
Amazing!! Perfect for anyone who owns a large cat breed like the maine coon. Cannot wait to use it outside with my boy = ) Most comfortable backpack ever!!

Well made but heavy
I like this dog carrier, it is well made and after I manage to install my pup in it (not an easy project) he seems comfortable. However, it is quite heavy on its own and that makes it a little bit of a challenge when I add its weight to my pup’s 60 pounds.

Game Changer!
My dog broke his toe and it never healed so we had to amputate the toe. We had a trip planned for Banff National Park and planned on bringing our dogs. We were going to be two weeks out of his toe amputation and we wanted to bring a pack for him since he hasn’t used that paw in awhile. I’m so glad we purchased this for him. It was a two person job to get my dog into the pack but once he’s in he’s snug as a bug. The pack seems very sturdy and it’s comfortable once it’s on you. Follow the measurements given and you should be fine. My dog is 40 lbs and the large fit him with his measurements. I’m so happy they make packs for bigger pups.

Worthless product
Used this twice for my dog and the zipper broke. The pack is only 2 months old and amazon says the return windo is closed. Total waste of 300 dollars.

A little snug for my 50-60lb boxer lab mix
The media could not be loaded. Overall it's a complete game changer. I got this one but will opt for the kollosus version that supports up to 80 lbs

Great product
Expensive but worth every dime. Staffie is close to 60 lbs and fits well. I can’t carry him on my back for too long, I’m 68, but it does the job when it’s too hot. Also has small removable back pack that works great. Highly recommended.
