I’ve had this backpack for a year — I am a 5’5” woman with an average build. My dog is a small terrier ~13lbs, and I purchased the small for him. He fits in it PERFECTLY! Absolutely loves it! However, I hate it after 10mins of use. It offers ZERO support for me, and my back starts to seriously ache. I honestly prefer putting my dog in my old school backpack because it has better support.

The straps on the Air 2 are too small and thin, and the chest band doesn’t do much to help — I wish there was a better option for the price. I won’t be buying one again unless a better version comes out at or around the same price.

Willy is living is best life. He is frenchie as you can tell and he gets tired after a small walk. This is a must for these types of dogs . He loves it.

My JRT turned 16 and I wanted to take her more places with me, especially after my second dog passed away. She is very fussy but took to this pack instantly. She’s very comfortable in it and loves to look around at her surroundings. Definitely worth the purchase!

My Maltese is only 6lbs and while he loves exploring, his little legs can only go so fast or so far. I’ve been able to bring him so many places in the sportsak (and get SO many comments everywhere we go). He loves that he is nice and secure and can see everything going on. He will even nap in it if he’s sleepy.

The only suggestion I would make is for the side pockets to be a little wider. When he’s in the XS sportsak, I can squeeze his leash and poop bags in one side and a small nylabone and a baggie of treats in the other. Would be helpful if they were water bottle size.

Overall awesome product and the customized patches make it even better!

I believe if the sack had an aluminum type of frame, it would help to place dog higher so they could see over my shoulder.
