    Nathan HPL #020 Hydration Vestis rated4.3333out of5by12.
    Rated5out of5byfromGreat Running PackBought this to replace an old Camelbak I've been running with for about ten years. I was looking for a vest design to make gels, salt tabs, etc. quickly accessible during long runs without having to constantly take a pack off to get into a pocket. Carried this on a 50 mile run and it was great. It holds a good amount of water and the front pockets stored more than I had even expected. Adjusts easily and doesn't flop on your back while running. Great investment.

    Rated4out of5byfromJust what I was looking forI have used the Nathan hydration vest for running and mountain biking. I like how it fits closely to my body, without impairing movement or bouncing. 70 ounces is the perfect amount of water for me. It has strategically placed pockets for my phone and snacks. I love this vest in every way except for one: although I have rinsed the tubing and bladder many times, I cannot get the chemical taste in my water to go away. I may have to resort to adding a powder, but I fear that that will make it harder to clean the tubing and bladder. But overall, I am VERY happy with this vest!

    Rated4out of5byfromDefinately worth the buy!*I purchased a replacement bladder (i left mine at home for a race) and the hook to attach it to the inside of the bag was MUCH better than the one that came with it. The original comes unhooked and falls down into the bottom of the pack. *lots of storeage areas *added a blinking reflector to the back and front upper chest for dark hour running/cycling *wish there were an I.C.E. contact card insert. *securely pin the end of the strapes after adjustments...they move too much and bother me. !!!DON'T WASH THE BLADDER OR TUBE WITH ANY LIQUID DISH DETERGENTS!!! *when done for the day, drain/empty and freeze until ready for next use (avoid bacteria growth). *****I LOVE MINE AND IT'S PERFECT FOR RUNNING****

    Rated5out of5byfromExcellent Marathon and below size vestI use this vest for my training runs under 30 miles. So far it has been the best hydration system I have owned. It is light, comfortable, and getting to your equipment is easy and convenient. It's 2L liquid capacity and extra water bottle holder offers ample hydration. The pocket on the left side easily holds a smartphone and a couple of energy bars or 3 or 4 gels. One of the best things about this vest is that there are plenty of straps that allow you to cinch the vest to your back tightly so the water doesn't slosh and throw off your balance (and I have had it on with a full 2L and drank it all so it never moved no matter what the liquid capacity). The only two "bad" points are that I wouldn't run an ultra in this because I think the carrying capacity for food is too small (not a problem with the vest as this isn't the biggest vest Nathan makes) and the valve could be a little larger so you get more water when you drink. This isn't a showstopper but it would be nice to have a wide mouth valve.

    Rated5out of5byfromLight and comfortableI ride 30 miles along the Pacific Ocean and this pack keeps my water cold and has enough room to place a wind breaker in case it turns cold or windy.

    Rated4out of5byfromConvenientI used this for running but experienced extensive rubbing on my back while running in a tank top. Expect it will rub through any light materiel if you tighten it enough to keep it from moving. Other than that, it's light and convenient to use. Love all of the pockets in just the right places.

    Rated5out of5byfromAs good as you hear it isI have put about 100 miles on this hydration system. Previously I relied on water bottles with a waist belt. I find that the Nathan vest is more comfortable than any waist belt system that I have owned. The one down side is that the tubing and water pouch can impart a nasty flavor on the water. This seems to be decreasing with use, however. I was initially worried that the placement of the main pouch would allow sweat accumulation on my back, but this has not caused any discomfort. As an added bonus, my nipples are less prone to chafing while wearing this vest as it tends to hold my shirt in place.

    Rated4out of5byfromDecent running hydration packRan my first marathon in May and knew I'd need to bring along a good amount of water. I'm primarily a treadmill runner (yes I run 20+ miles on my treadmill on a regular basis :) ) so I'm used to being able to set up a row of water bottles by me and not have to carry or wear anything. That means I am not used to carrying weight or having something like a backpack rubbing on my back/neck at all let alone for 5 hours. I grabbed this pack and a Camelback with the same capacity to see which one wouldn't kill me. I liked the lower cut at the neckline of the Camelback but this one was more secure feeling and didn't feel like it'd be bouncing around the whole time. I also really liked all the storage in this pack, having the pockets on the straps where I could stash gum and Gu was GREAT! The high cut at the back of the neck was a little annoying at first but it didn't chaffe and that was the most critical concern to me. I did end up with a bit of a hole worn in my back on one side where it rubbed but I must have missed that spot with the lotion because the other side was fine. All and all I finished the race with water left and everything where I could reach it and only a minor sore so I was happy! I'm not sure if I'll use it again for another race, halves suit me better and I have a waist water pack that is good for that distance but if I ever do want to tackle another full I won't hesitate dusting this off again rather than shopping for something else. One tip I will offer, REALLY clean it well before use including the tube. I washed it up the night before and left water in it overnight to finish soaking out all the icky taste. I emptied it completely after 8 hours and refilled it with fresh water and taste tested and it was fine. It took a while to get to the race, get started, and get a couple miles in to where I first needed a drink and by then the water in the tube was GROSS. I had to spit it out it tasted so bad. I tried to keep drinking enough to clear the tube every half hour or so and it was ok, but if I let it go too long I could start to taste chemicals again. It seems like I had the same issue with my Camelback waist pack so I might just not really be getting enough water through before first use when I get a new pack.
