Review on 🏃 Nathan Men’s VaporKrar 4L 2.0 Hydration Pack/Running Vest - 4L Capacity with Twin 20 oz Soft flasks, Hydration Backpack Ideal for Running, Marathon, Hiking, Cycling by Elmito Yeager

This backpack was light and had a lot of storage space. Unlike the vape zipper, I found the straw loops to be large enough to easily slide bottles in and out and get them to my mouth while strapped in place with no kinks. The waterproof phone case is a great and quite comfortable place for my large Galaxy S9+ when you turn the soft back of the bottle inside out. The material isn't too stretchy, but it stretches enough after tearing that I had to scale it down. My chest is about 38.5 inches at the bottom of the breastbone and just over 41 inches under the armpits and I went the small size. I've had it despite a few runs on technical terrain as well as road and am happy with it.
