Customer Reviews
Lightweight, well-balanced functional running backpack with pockets for all the essentials. Currently perfect for suburban training interval runs. Some style limitations with loose straps and more 'outdoorsy' aesthetic. However, great value for price and purpose.
This is very flattering, comfortable to wear, and I really love the pocket options!
This is the perfect hydration backpack for day hikes or outdoor exercising like running or biking. I like how it has a few pockets for things other than the water bladder, and the color options are nice! I went with black. The material feels really high quality too. I'm expecting this to last a while.
I love this hydration pack. I hate carrying a water bottle buy want water and snacks with me. This has two pockets on the shoulder straps that are on your chest for easy access, I love that so much. I can drink some water and get a snack without having to take off the pack, this is what you want on every hike. It is so light weight and comfortable and just the right about of water. It fits across my chest perfectly and clicks in front to take the weight off my shoulders.
I purchased the Everfun Hydration Backpack Running vest so I can run without holding a water bottle in my hand and holding a phone in the other if my pockets are not tight to my leg resulting in my phone just banging around my leg..not so fun when running. The running vest is light and fits my utility needs: holding the heaviest item in water bladder on my back, small items such as a snack, gloves, phone, hat and more in smaller pockets in the back pockets or front.. where you could store smaller water bottles like the solomon soft flasks. My only concern is the longevity of the bag, probably made from China.. resulting in poor materials. This may be true or not, what made me say that was because of the lightweight material..especially the lightweight material on the shoulder straps.. thin material. Overall, this is a wonderful running vest with what I will be using this for.
Last thing, the straw for the pack was too long for the straw holder on the shoulder strap.. I had to adjust it to the proper size by cutting the straw and using a heat gun to attach the straw back to the mouthpiece.. which is not an abnormal thing to do.
Thank you everfun for making a great running vest,
Jesse R.
