K9 Sport Sack | Kolossus Dog Carrier Backpack - Medium to Large Dogs | Front Facing Adjustable Dog Backpack Carrier | Fully Ventilated | Veterinarian Approved (X-Large, Kolossus - Green)

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.

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.

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 :)

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.

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.

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

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.

This is a very well crafted pup-pack. For reference, I have a 65lbs. Staffy / pit / pibble and we bought the XXL size. My boy is food motivated so it was mostly easy to get him in the pack (AFTER watching the tutorial video - make sure you watch that). The pack has lots of support, and I felt like my dog would be very safe in this pack.I sadly returned it because it felt like we may not use it enough to justify the cost, but if you’re a hiker, or carry your dog enough, this seems amazing. I would still recommend it, I just can’t speak on its lifetime of wear or durability. Seems like an amazing product though and would absolutely buy again if I could truly afford it
