Perfect for Running, Hiking, and Biking

This Camelbak is flat out amazing. I love to hike, bike, and run and this is one of the few backpacks that allows a person to do all three. Running is easy with this backpack. I used to carry a water bottle around with me while I ran and my arm would start to get sore after the first hour. I can now run pain free for over three hours and I hardly even notice the backpack is there. This backpack is well worth $115, but since Amazon is such an amazing store, the Camelbak Mule NV is only about $85. If you buy this Camelbak you will not regret it.

I bought this for long runs to use my LG G5 for GPS tracking and for wireless music streaming. Ill never go back to using a waist belt again or a running shirt with a phone pocket. This keeps the phone fixed to you and has enough room to carry your essentials.

I found the arm strap to be perfect and adjustable for my smaller arms, and I generally pack a house key and ID and a credit card with some cash, and haven't had any issues with the bulge or any discomfort.

I would say that over time, there is a little bit of sweat moisture that is absorbed by the band, but I haven't had any issues with the inside window getting fogged up or anything. Also, theres plenty of touch sensitivity when using this, I haven't found any issues with functionality, its just that side buttons are a little less easy to use. But mostly I control volume and skip from my Bluetooth headphones.

Ive tried a number of these in the past and this one seems to be the most versatile for carrying stuff. With longer runs Id say that theres the tendency to feel some arm fatigue because of the extra weight swinging on my upper arm but I switch arms every run.

I wouldnt hesitate to give this as a gift for my runner friends and family since its great for any short or long distance runners.

Item shipped quickly and was packaged securely in the packaging without any damage and the seller was very courteous and provided updates throughout the process.

I received this item at a discount and am providing an honest, unbiased review. My words are my own and I enjoy providing feedback to the Amazon community since reading reviews is imperative for me whenever I try out a product, so I believe in giving back and providing my own feedback as well.

I bought this for ultra-marathon trail running.  Perfect for all the mandatory gear, easily accessible pockets, lightweight, comfortable and a perfect fit for the small to medium person (female).

I purchased this running belt because I needed something that fit water and had a pouch big enough to fit my phone with a case on it because the case is hard to take off. The zipper pouch fit my phone (iPhone 6s with an OtterBox defender case on it) and still has room to fit keys and other little things that one might need to carry when hiking or running. I haven't quite figured out what the outside pockets could be used for but they might come in handy in the future. It came with two 10-oz water bottles and from what I can tell water doesn't leak out of the cap. It is comfortable to wear and fits nicely on the back or on the stomach and doesn't get in the way of my arms in either position.

Nathan is owned by two ultra-marathoners and adventure racers. They understand the needs of long distance racing and the training that comes with it. They do more than just interview elite endurance athletes to understand their needs - they race alongside them!

I've been a hand-held/strap-on water bottle ultra-runner kind of guy for the past 10 years, but finally felt it was time to step up to being hands free. This also meant giving myself more hydration in between aid stations when racing - a welcome upgrade.

I hit my running store and they immediately said that the Nathan product was the way to go. I was in agreement just by looking at the HPL #008 1.5 litre hydration vest. It was almost clinical in appeal - no bells or whistles, no neon colors, no overabundant branding. It seemed light - and the mesh felt like something invented for NASA. I bought it - eagerly awaiting to head out into the hills and have it quench my thirst.

I tested it out on a 30 degree Celsius morning at Shuswap Lake in the interior of British Columbia. I loaded up a total of about 1 litre of water, knowing I'd only need that much for the day's hydration requirements. A logging road meanders through some low lying mountains on the north side of the lake, I headed out and back for a total of 24km. At the outset I simply threw the pack on without adjusting, then realized that it has a dual-strap adjustment toggle. It allows for the vest to move more fluidly with your body while you are in motion. I liked the idea of this - while light-weight and simple in design, it incorporates some ingenius but subtle engineering that really benefits the athlete.

It took me a couple of minutes to figure out to pull the mouthpiece up in order to open the valve - my bad - like I said, I'm used to a water bottle. A bit of sloshing was evident, but I don't expect any noise cancellation or motion control technology to be attached to my hydration vest... (yet!). The rear of the pack has an elasticized storage pouch, room for plenty of fuel, gloves or a headlamp. The two front pouches are perfect and easily accessed, one is zippered, the other is open for quick access to a few gels, an iPod or a small bottle of an alternative liquid. The mesh breathed well and I didn't feel any irritation - in fact it seemed to cling to my technical singlet so there was no real friction to speak of.

This is a fantastic product - I highly recommend it, and will continue to look for Nathan products when they suit my needs.

Having SUCH a great time with this pack! I intended to use it for longer runs, but I find I'm wearing it for even more (also 5-8 mile runs sometimes) because it's so useful and comfortable! I barely know I'm wearing it. It definitely fits more like a vest than a pack.

I purchased two Body Bottles from Ultimate Direction, because other reviewers had complained about the sloshing of the standard bottles. These bottles also provide just a little more water. I have not put a bladder in this pack. I've been storing a first-aid kit, hat, gloves in the back once I warm up on the trails.

The color is pretty cool, and I'm someone who hates pink. I was hesitant and thought I'd wait for an update, but I'm glad I made the purchase.

My main complaint is the zipper pouch that is the obvious location to store your phone. It barely holds an iPhone 5 with a thin case, so I'm certain I'll need to find another solution (within this pack) when I upgrade to an iPhone 6. My phone is what I want closest for fun running photos!

I spent a lot of time looking for a hydration pack that met what I was looking for. I wanted a pack that had a 2L bladder, space to hold extra snacks (but not too big), camera, phone etc., that I could take on hikes. I wanted straps across the chest and hips and I wanted it to be lightweight. This pack meets all of those requirements! I was nervous it would be bigger than I wanted because I read a review that had pictures of a man wearing it and it appeared to fit him the way I'd want it to fit me (and I'm a petite person 5'2, 115lbs). BUT when it got here I tried it on and it fits GREAT. Its slightly larger than the hydration packs that runners typically use just for holding the water bladder but smaller than any normal backpack. Perfect for a long hike. I love that it has pockets on the hip straps for easy access to phone or camera. I also like that the back is mesh and slightly padded so its very comfortable. The hydration system works great with an easy to remove cap on the mouthpiece.

I put in about 200 trail miles on this running vest now with the longest one being 20 and these are my observations

-The fit is very easy to dial in. I put it on, tug the side straps and snug up the chest to a comfortable tension and then I go run. Fine tuning is just as easy and can be done without stopping. Expect to give the side straps a tug or two as the bladder empties so everything stays bounce free and stable.

-The materials used are very soft so I can run shirtless without chafing. This is important to me in the summer so I don't get a farmer's tan :)

- I handwash the bag after each run and hang dry. So far so good. No stitches have come undone and the color hasn't faded. The yellow Nathan letters are starting to peel but it gives the bag some character IMO.

-I like the easy to turn inside out bladder. It makes it no hassle to fill it with my electrolyte drink and thoroughly clean it afterward. To prevent the bladder from sloshing I fill it, turn it upside down and suck all the air out of it before putting it in the pack. To prevent it from falling off the hanger, I give the hanger loop a twist then hang the bladder (making sure the hose side isn't against my back). The plastic taste went away after a few uses.

-The capacity is just right for my part of SOCAL and the times of day I run. The pockets up front have enough room for my gels, a couple of bars, my chapstick and a small container of salt tabs plus my music player/phone (iPhone 5 in a Zagg case in case you need a size reference). The bungee strap holds a windbreaker or shirt and the pocket in the back holds my keys, small first aid kit, ID, a couple more bars and a small Leatherman. I can put more stuff next to the bladder in its compartment if needed.

For longer runs I augment this pack with a handheld bottle (Nathan Speed Draw)

All in all, a great pack at a great price. Buy with confidence.

I bought this to run a 7.4 mile run in SF. It fits very snug when adjusted properly and doesn't bounce with each step while running. It's almost unnoticeable because it fits so well.

The pockets are perfect for a cell phone, wallet, camera, GU packs, etc.

I would recommend this for any run over 3 miles. It's awesome.

I've used different brands of hydration bags for running/cycling & this is the best by far. Almost no bounce on the pack whilst trail running & bombing down the slopes. Lots of storage space in the pack for whatever gear you'll need during your adventures. Super comfy & cool on runs even in hot & humid weather. Been using it for 2mths now with no chafing on my shoulders. Chest straps are excellent. I only have 2 gripes.

1) Capacity of the hydration bag would be perfect if it were 2L capacity instead of 1.5L.

2) Having the bite valve/tube come under the arm is great but it tends to flap around dangerously near my face/eye during runs. (had to improvise a way to secure it before I maim myself)

Overall I would purchase this pack again if I had to.

I have used this product for quite a few miles now and I am happy with it. I can fit all of my must haves comfortably - of course I try to pack really light when I go on a run to avoid too much shaking (cards, phone, some change, SPF lip balm, eye drops, 1 key and fob ... all fit in the belt). I noticed that the items tend to get wet with abundant sweating, so I am planning on storing my phone in a water tight bag in the future. I use a bluetooth headset and I rarely take my phone out during a run, so it works for me.
The materials seem strong and durable. It fits comfortably low on the waist, and I barely notice it while running.

This product is amazing - I love how smooth the texture is! The size is great for running, hiking or biking... I tend to sweat quite a bit (eww) while running and this more than handled it!
Super easy to wash and get back in the drawstring mesh bag.
Love love love it!

Its really hard to find a pair of headphones that sounds good and fits well at the same time. These are the exception! The Bluetooth connection is great, it connects even over 10 feet away, and it works flawlessly with my iPhone 6. The style is really clever, with a comfortable ear rest, and easy access to the controls. Theyre the perfect set to wear during a run or a bike ride, and they stay put, which is important for any active person. The charge process is super easy and the battery life is also excellent. Im so glad to have these!

I like these a lot for hiking, biking and any sports. Backpacking they take up  little weight. I originally saw these in a backpacking store.
But I didn't think I would pay this much for underwear, but it is worth it I bought two more. If cheaper they would get 5 stars

I've wanted a small backpack to take hiking/biking for a while and finally I landed on this one. It's exactly what I was looking for! It's got enough pockets for quite a few small things (my large iphone 6 plus fits in the big pocket on the front), it can fit two water bottles in the side pockets, and the helmet-holding mesh pocket is a fantastic addition to this little gem. I'd highly recommend this product. I used it all summer and it still looks brand-new.
