My hose connector is from someones old baby bottle tutorial on here!
It's worked pretty well thus far. Sometimes it's a pain to get it wedged between there to tighten. It came disconnected a few times when I was trying it on so the couple times I went out with it, I've just started tucking the connector into the leg pocket and zipping it up. It's not goin anywhere and the hose is still a cool part of the suit without the connector.
I mean when it's on there good and tight, it's not going anywhere. I think it wasn't done good enough those few times.
That's a pretty easy cheap solution. I think I may try to make a better one one of these days though.
