The good: This sling is very comfortable to carry due to the very wide strap, which is a very hard to find feature in small pet slings, and it is comfortable for my cat no matter if he wants to nap or sit up and lean his head out the side. The little pockets in the carrier are large enough to be useful and hold everything in my purse too without deforming the carrier!
Now the bad parts: I am average height (5 foot 6) and even at it's shortest the strap is ridiculously long, and I don't really want to shorten it that much because the strap bunches up uncomfortably when fully shortened. The pouch made to pack the sling inside is pointless, it's laughably large, it's about the size of a standard piece of paper and even folded loosely the sling is swimming in it. The point of packability is to save space and this sling has extra room in the pouch even when folded loosely. It easily fits in a pouch a third the size of the one that comes with it, so if you're getting this because you want a packable sling plan to provide your own bag. The soft construction of the bag makes it easy to compress though!
