I was looking for Hydration Vests and came across this for my wife, only size XS in stock (To Fit:81.5 − 86.5 cm | Measure @ widest point of chest). Seemed like a pretty good deal if you're looking for something like this and you can fit it.
Fairly low stock so get in quick.
The cheapest men's I could find are $112 from the Salomon site. I still haven't pulled the trigger on that yet.
