Alright so I got this with my two Wrap Tais and i gotta say I love it! It slips down my shoulder sometimes but I pack the thing so its to be expected. Its holding up really well as of yet and is really soft! I use it for trips around town and I've hung it on my stroller and have had no issues. My youngest likes to hold onto the strap while im wearing her and it and my middle likes to rub the strap(s). Highly recommend getting it!
I love this bag, even if I have to steal it back from the kids. It's soft straight out of the package, thoughtfully designed, and roomy. I would rather have snaps than velcro, but that's easy enough to change.
