Lovtour Hydration Race Vest,2.5L Running Vest Lightweight Pack with 2 Soft Water Bottles Bladder for Marathoner Running Race Cycling Hiking Camping Biking

It didn't feel that great when I first tried it on but with filled water bottles it was much better. I actually had to cinch the straps tighter during the run. The pocket fits the bundled 500ml bottles very well. One piece of advice for all: don't use cold water in those bottles...it doesn't make for a very comfortable feeling on the chest to start a run that way.

I bought this for my sister and she loved it. She will be running her marathon with it next year!

I'm not sure who these are sized for but it's certainly not an adult and definitely not an adult with boobs. Got the XL and it's still laughably small.

Very small. The collapsible bottles are nice.

I’m 6’1, 200 pound man. The large size fits me perfectly. The flex water bottles work great and many pockets for stuff that I’ll need for my runs. Very glad I found this product. Didn’t want to spend 160$ for a similar product.

I love this vest! Fits similar to my Solomon vests. For reference I wear size M in the current adv skin and M/L in the older models. In this vest M/L was the perfect size for me.

I have used this 3 times and it is doing well. It holds the bottles well and they haven't leaked. It didn't take long to get used to wearing it which surprised me. I want to try it on a hot and humid run to see if I like it on those days.

- The usefulness of this hydration vest I find isfor shorter hikes or trail runs (about 2 hrs) or events with aid stations.- I would have liked if the pocket on the back had a way to close (zipper, velcro or similar) - I am afraid to lose something
