I bought this to go with my Ergo Sport carrier. When I am out and about I hate carrying a purse when wearing my Ergo just because I need a place to stash my keys wallet and cell phone. This works perfectly. It fits my large wallet some hand sanitizer, lip gloss, cell phone, keys and some cash. I never have to carry a purse when I wear my little one!
It fits nicely on the belt.
When I position it on the front of the ergo my husband says it looks like a fanny pack and he refuses to wear it like that..lol He wears it on the side of the belt.
