If traditional vests haven't worked try this!
I have run every distance from 5k-100 miles and tried every pack there is and none of them have worked due to being uncomfortable or chafing etc. My favorite vest currently is the Naked Vest but it can only hold so much and so for a point to point course, especially if a race has mandatory kit they are not big enough. So when I saw this vest which has a similar bra/tank top like style. I jumped on it. Of all the vests out there this size it is the best I have tried but they could make a few updates for version 2 including making it thinner (it can get pretty hot) and they have all these great openings in front but they all open into the same big pocket which is mostly useless for keeping things organized and I have had things get on top of each other (like my phone and keys) causing digging into my chest. Maybe if it was tighter this would not happen? I bought a medium cause I am a medium person (5'5 135lbs) and need room to layer in winter. I read a review of someone who got small and said the zipper kept coming undone amd they should have gone with medium. So maybe I could have done small but then IDK? Its hard when you cant try on. Overall it is an expensive pack but well worth is because its comfortable with no chafing and can carry so so much! I am happy with my purchase and would consider also getting a small if they go on sale just so I can have more options.
