Nathan QuickStart 2.0 4 Liter Hydration Pack with 1.5L Bladder, Front & Back Pockets for Essential Storage, Breathable & Moisture Wicking, Unisex

My first hydration vest and I love it! Fits so much and love the look. Before this, I had a waist pack but didn't like carrying the extra weight there.

I bought the XL women size (which was significantly cheaper), which fits well as a medium man. There was an issue with one of the bottle caps, and they sent me a replacement immediately.

These vests are very nice. If you order the right size there is absolutety no bounce. There are plenty pockets and spaces to tuck items for your run. The flasks are easy to put in the pockets when filled. We really like these and are very happy with our purchase. The only thing we would prefer to have is that the two flasks would come with flip tops for quick and easy refill, rather than the screw on tops.

It works well but I had to reinforce the interior because with the weird of the water bag, the sector where the hables are, were broken. After that there were no problems. The fabric is soft, no skratches with the skin. The pockets are big enough for an iPhone.

So worth it! I used this for marathon training and hiking!! Keeps water cool on those hot days and it’s not awkward when running.

I was a little nervous after putting it on after it was delivered and how tight it felt, but once I took it out running it was perfect. Fits nice and snug and doesn't move or bounce at all when running the trails. I was right on the border of a small and medium when I measured and went with the small and I think I made the right choice. I'm just under 6ft and 180lbs.

This is a really nice running vest.But is seems a little strange that I, a 41 year old, complete normal build guy, have to get a women's XL ???I have tried all sizes and the only one that fits is the women's XL. But okay, that is not a big problem just a really big pain in the ass buying and returning. Also a big waste of resources!!A real problem is that both soft flask are leaking (one only a little bit, the other a lot). Maybe I am just really unlucky. We will see after contacting Nathan, which I will right now and give you an update as soon as I hear back from them.

This is the best piece of gear I’ve ever bought. I am 5’3 and 143 pounds and bought a small. It fits perfectly. No chafing, no moving around, zipper pockets fit my iPhone and all the extra pockets are so helpful to hold keys, gloves, ect. It took me a little bit of time to figure out how to fill the bladder but I watched a YouTube video and it cleared that up. The water doesn’t slosh around an excessive amount and stays pretty cool. I love this thing so much!!! Worth every dollar.

Really well made - love them

Fast, easy, accurate order, name brand authentic.

Great product. Only issue I have with it is that the chest strap loosens as you run. Not hard to tighten while running though. Highly recommend this.

I absolutely love my Nathan. Only complaint is I with there was another hook on the other side so the mouth piece just doesn’t hang down. But I just put it under the top strap and it stays. But it’s so incredibly comfortable. I’m so happy I bought it. No regrets

Phone pocket opening should be little more bigger. I have iPhone 13 Pro Max , I’m able get that in the pocket but little wiggling required but ones in it fits in the pocket. Overall the product is good.
