      It’s exceptionally

      Well so far only used a few times, Whiskey our border terrier seems to like it as well. A little tricky at first, but watching the video definitely helps

      Happy but sad

      Happy with the sport sack but sad that was unable to get a personalized name patch. Only accessible thru the US company and shipping was twice as much as the patch..oh well. Still happy and so is Cooper the Corgi.

      Not comfy at all and broke first use.

      Very uncomfortable on your shoulders. One of the plastic black buckles broke well using it for the first time. I have a small min pin 10 pounds so it’s not that the dog is too big, and I am used to carrying him in a back pack. I will have to purchase something better. It’s to bad I was really hopefully for this backpack carrier.
