NathanVaporAir Lite 4 Liter Vest & Hydration Pack with 2L Bladder, Front Water Bottle Pockets, Soft & Breathable Material for Comfort

I do like this vest. I like all the pockets and the material is good quality. Easy to wash. Only complaint is it runs a little small in the chest.

First running vest. Very comfortable, no chaffing, and perfect for long runs on the trail.

This was my first ever running backpack and Nathan product. I got it for a half marathon earlier this year. I’ve only had it for several months, used it maybe 30 times, and today on my run the seem at the bottom of the bladder separated and leaked all over me. I’ve reached out to Nathan’s to see if there are any replacement options, but I’m quite disappointed in this product’s quality. It already didn’t fit great, but I was willing to keep giving it a try. After this situation though I don’t think I’ll ever buy another one.

Let me tell you - I AM NOT A RUNNER. However, my wife is at minimum a yearly marathon runner and it seems like she goes through vests like candy. She runs these into the ground. So, it was time to buy a new one for her and this one seemed to fit the bill. I will give you here pros and cons.Pros:1) great fit2) comes with water bladder3) comfortable4) more adjustable than any other vest she has had, even other Nathan vests5) no rubbing on long runs6) plenty of pockets/storage7) Large enough water flask pockets in front for two 20oz flasksCons:1.) doesn't come with flasksHonestly, for this price point BUY IT. You won't regret it.

The product itself seems good as a hydration vest. However, I could not use the product because even fully extended, the chest straps were too tight. I purchased the L-XXL size. This could work for someone with a slender build. But likely not a medium build.

Great product. When you get it remember it’s adjustable. I almost sent it back because it was too small until I adjusted the Velcro and the straps. My only regret is not buying it sooner. Also don’t forget to burp the bladder before putting it in the vest to reduce/eliminate the sloshing. Google it for full instructions

Too small based on description

The size states L-XXL. This size is probably for children?! I am 6' and 185lbs. I can't strap the vest together and still expand my lungs while running. Ridiculous sizing for a vest. What a waste of money. 👎

Fits like woman’s size not men’s.
