Surprise!  It's adjustable

Quite cute.  It fit even better than expected because it has elastic tabs that can be adjusted and buttoned down inside the waist.  An unexpected surprise that allows you to be a little large on the sizing and it not be a catastrophe.

It's not as light as I thought it would be, but after crashing with it at Snow Summit, I'm okay with that. It saved me big time. It is very adjustable and works well with a Leatt brace. MTB and Moto

the straps allow for a lot of adjustment.  this felt really comfortable the moment i put it on.  i'm between a dd & ddd, & kept the dd, but didn't want to go up to the next size (afraid it w/ be too big).

Mine ended up being too small, but it was very difficult to adjust as its plastic, the other one I have is an elastic material. Maybe because its a pattern. Hope this helps.

I saw one of these on a dog recently and wrote down the name.  Hoping the one I bought will fit my new puppy at some stage, it is not very adjustable.  If it fits, it gets 5 stars.

Why did I wait so long to get this? Adjustable, stretchy, and worth the money to be hands free!

Took me a while to get used to it, but it works well. Good adjustability up / down and side to side.
