8L Pro Running Vest – The Ultimate Hydration Companion for Long-Distance Trail Runners
Run my first half marathon with this hydration pack and it was perfect!! Easy to assembly and was adjustable. Great storage area for keys and gels. Very light weight
Ive tried a few hydration options over the years, but this running vest is by far my favorite. Its lightweight, breathable, and doesnt bounce aroundhuge win during long runs or races. I love all the pockets. I can fit snacks, my phone, keys, and even a small first aid kit without it feeling bulky.
It fits me quite well, and has about as much internal storage as you would expect.
In addition, the material is actually quite good, I have never had any additional chafing caused by wearing this Running Vest.
love this, has pockets and is adjustable
I love this for my long runs. It holds my water, gels, keys, and phone easily while not bouncing too much. Easy to adjust, very light and comfortable.
Exactly as adversitied. Good material. Easy to adjust.
Super running vest! Lightweight and breathable but can fit quite a bit inside. Comes with a water bag also however I keep my water bottle in the back and run with it . Plenty of room in the front for phone keys headphones etc. great lightweight running / sports bag. Have used on long and short runs.
The adjustable straps make it easy to get a secure fit. Doesn't slide around.
