NathanQuickStart 2.0 4L (Liter) Hydration Pack with 1.5L Bladder, Front & Back Pockets for Essential Storage, Breathable & Moisture Wicking.

I’m used to using Camelbaks for hydration here in the Arizona heat when I hike so I can tell a good product from a bad one. This pack is pretty great! It has a soft shell with adjustable belts and is very lightweight. I chose the red color and love it. It is definitely a smaller form factor, but it has a lot of storage including on either shoulder strap and in the back as well. It is it has a mesh backing that will allow your back to breathe unlike some other packs I’ve used. The nipple is comfortable and doesn’t leak. This holds plenty of water for my 1-2 hour hikes. As an Arizona resident that has owned several hydration packs and use them in the sweltering heat, trust me when I say this is a great pack and value for your money!

I got this hydration pack to use on 5 to 10 mile walks I take regularly. I was tired of using a handheld water bottle and running out of water so I thought I would try this. It is a good size water pack, a 4L pack size and 1.5L reservoir, that works well for the type of distances I generally walk. It definitely serves the purpose of keeping me hydrated.It also comes with multiple carrying pockets to hold things such as your phone, keys, wallet, and things you might want to take as you walk. It really utilizes the space of the pack from the front to lower pockets. I like that the pack has reflective detailing work because I often walk later in the evening after work. It's great for safety during early morning or late afternoon walks.I'm a 6'2"/230lb guy and I wear a L or XL size t-shirt. This hydration pack was easy to put on and adjust, however I do have to wear it at almost the largest setting. The fabric was durable and more comfortable than I expected. The pack fit me easily, but it may be a tight fit for people who are larger than I am.This is a good hydration pack for the price. It's comfortable and easy to use, and has a bladder that holds enough water to stay hydrated and pockets for additional storage.

I have a few different brand running vests with Nathan VaporMag Running Hydration Pack for Women, being one of my favorites. This Blue Nathan slightly different model with a bag instead of bottles. It is weightier and has more fabric and buckles. It has the bottle cap wide mouth fill hole. One thing I find nice with bladder back packs is using them for long river trip bike rides in the heat because you can fill the bladder with cold water and ice, and even put it in the freezer for a short while before heading out. Wearing it keeps the core cooler for a while.The buckles are standard squeeze type, and while a little bulkier they are simple to use and almost always click into place. These are on a sliding bar and not fixed into place which makes for fine tune adjustment for the wearer and how they want the straps to cross their chest.The fabric is softer than any pack I currently own. Going to be interesting to see how well it handles multiple washings. I included many photos in just comparison with my favorite Nathan VaporMag. The pull type bite piece works nice.

I don't normally write reviews in general, but after reading the positive reviews here, I was incredibly disappointed by the quality of this product. I shelled out the extra cash for this brand because it had come recommended to me. I took it for a single long run, and by the time I was back home, the bladder had ripped significantly. Reached out to customer support, and have yet to hear back.

It’s not easy to drink from it.

Sizing:This vest is for the most part one size fits all. I'm 6 foot tall, weigh 205 pounds, and have a 46 inch chest, and this vest fits me very well; not too tight, not too loose.Storage:There's a small amount of storage in the front, and a decent amount in the back. I Feel that the amount of storage provided is just enough for the days I'm going to be running 8-10 miles on the road or trail, or I'm going to be hiking 10-15 miles.Hydration reservoir:The hydration reservoir is quite large, which is the primary reason I consider this to be a high mileage vest. I've never used this vest and ran out of water while out on a long run, or long hike. Also, I love how the hydration vest is positioned, as well as the drinking spigot.Fit while running:While the hydration reservoir is very large, and storage more plentiful, this vest never bounces around on me, as long as I have the vest properly tightened down.Bottom line:This is a great option for high mileage running, and hiking.5 stars

I LOVE these hydration vests! I use these for when I'm trail running and these have been a life saver. They hold a ton of water, have plenty of pockets for holding my keys, phone, cards, etc. It is also very comfortable and easy to adjust the fit. I haven't had any issues with durability, either. I've even thrown it into the laundry with heavy items and it's been fine so far!

I live in Louisiana and even the easiest/shortest of walks and hikes require hydration. It is very hot and humid year round here. This is perfect for when I'm taking my Great Dane for his daily walks. I can keep my hands free to maintain control of my big boy. It has storage compartments for small extras like keys, ID cards and your music device / phone. Nice quality hydration pack. Would order again.

I bought this vest for my full marathon training during summer. The product came in good quality, bladder holds water without leaks. The material is breathable and light. If you are running long slow distance in summer, this is a must-have.
