any recommendation for good whitewater life vest?

[mauitomo]

I am very new to river /white water stand up paddle and need to purchase a life vest, I heard that with quick release is a good one to have. we don't have anything around where I live and I have no way to try it on, I will be going on a trip and paddling down for  3 weeks so I want to have one that doesn't restrict my arm movement and I am also small so I would love to get something that fits me well.
will you please give me any recommendation?
any other advise ( besides life vest ) is appreciated as well!
Thank you.

Astral Green Vest is the best I have tried.
Colorado Kayak Supply probably has them in stock too.

thank you, I checked the website, what do you think of Astral Wonderjacket PFD Life Jacket? is there much difference? just because I found 50% off on these and it says designed to fit women and shorter torso( I am 5ft so)
but if it really is worth to buy astral green I would sor sure, thank you for your help.
does quick release comes with those jacket? or do you have to out it on your own? and  are your leash goes from board to the jacket or??
sorry I sound like an idiot not knowing anything.
