Yeah, like a big scarf sort of? They do, I don't trust them... I'm sure they're safe enough, but they have way safer ones I feel like!
I'm not sure do you know if they have ones that just tie?
Are you talking about like a front pack that your baby sits in? If so, I have one and I absolutely love it! Obviously there are risks with anything you put your baby in! Mine clips and velcros in three different places to hold my son in and then there are two clips with adjustable straps for me. It's a lifesaver when he wants to be held but I want to eat or clean. Also, it's good for like long trips places like either a fair or shopping and not trying stuff on, much easier than a stroller (:
