Review on Streamlined Running Backpack By FITLY For The Minimalist Athlete by Geoff Yates

I've tried a lot of hydration packs. I tried two from Orange Mud (i like the bottle option) Single barrel and vest pack 2, Nathan Trailmix 7L, just to name a few. This one is the best. It don't change the way i swing my arms like the others. I had to run with my arms out to not rub on the packs. You don't have to on this one. You don't notice it on you as much. I love the soft flask this uses. Easy to clean and dry. I also purchased a 13.5 oz soft flask to put in the pack. So its like running with the amount of 2 water bottles. I think enough for a 13.1 miles, if not too hot outside. I have used it for my 14 mile, 13 mile, 10 mile, 18 mile and 20 mile runs. Anything over 13, you may need to refill water. But this is so far the best one I have used. Used it with a t-shirt, sweater and shirtless. It does chafe on my chest (when shirtless) but not enough to stop using. I hope they make a new model a little bigger to hold 2 of the 17oz flask with the tubbing for both.
