Hey @Elsa!

I'd love to chat running hydration vests with you!  I'd definitely suggest trying a few on, it's almost as personal to fit as your running shoes.  But...some of my favorites from personal experience are the Salomon S-Lab vests, Ultimate Direction Ultra Vesta or the Nathan Vapor Howe.  Other factors to consider are do you prefer a back bladder or soft flasks in the front pockets?  Personally, I lean towards soft flasks in front...easier to refill at aid stations and less sloshing around.  Hope that at least helps to get you started!
