The good: Really well made and durable materials. ... I 'm a hydration pack fanatic because I use them several times a week. This one is quite good. ... It has some internal pockets in the main compartment that really distributes your stuff and the weight well and keeps the pack well

It's a convenient size for everything I need on hikes. I absolutely love the backpack. It is extremely durable and well- made and very well thought out. It has tons of storage, hip belt and the hydration bladder is a plus as this helps cut down on the bulk of multiple water bottles. It is easy to access things in the side pockets without taking the whole backpack off. It's lightweight and feels less bulky than my old hiking bag.

The backpack has been used while hiking and biking! Amazing quality! Very lightweight get sturdy and reliable. Holds a good amount of water and very comfortable on my back! A must have in your outdoor adventure!

5 Shauna
This backpack has been great for day hikes. There is great padding in this pack. You don ’ t feel any odd objects in your back that might end up poking through to your back area. Hydration bladder is easy to fill and drink out of as well.

Love the size and color! I can not wait to use this once the weather warms up in Illinois. It is the perfect size for a 4- 6 hour hike. Material is durable as well. I gave this 5 stars because of the size and look so far. It may change after I first use it. Love the straps on the back so it stays in place as you are walking.

5 Matt
Went for a hike with this new backpack that had the hydration sack in it. One of the best products I ’ ve got to try out and I absolutely love it. Slotty other than carrying a water bottle around inside of your backpack or attached to your backpack weighing you down. Absolutely buy another one.

I love my Big Agnes 32L pack for long trips abroad but sometimes you need a smaller pack for hikes, light travel, etc. This Osprey fills the bill and I am very impressed with the design. They are well known for the quality and it is obvious in this pack.

5 Glicker
This is my first day pack with internal frame. It makes it very comfortable to wear, balancing the weight down onto my hips( even unbelted and even wearing it on one shoulder) and the frame with mesh back keeps my back cooler even in 93 degree humid weather. The pockets are n't ideal. The top front pocket is very small( and if you put a heavy phone there it is unbalanced). The internal( water or laptop) pocket is deep- so anything small put in there is lost to posterity( beware). The water bottle pockets on the side fit a smaller water bottle easily but tougher with anything larger. I used it as a carry on( personal item) and no complaints from the flight attendants about how it fit under the seat in front of me, though the top did stick out a little and I found it to be a bit in the way of stretching my lets. It fit a ton of stuff- I had an umbrella and rain jacket, wallet, cosmetic size bag with electronic cables and earbuds, cosmetic bag with actual cosmetics, book, magazine, two journals, an airport shopping bag( small), and small cosmetic bag with meds in there. There is a helpful clip to attach your neck pillow! It also has a rain cover in a pouch at the bottom that was very useful in a downpour, if a little hard to extract and put in place on the fly.

I ’ ve been using this backpack for a while now and I have to say, one of its great features is the smart design that balances comfort and functionality. The padded shoulder straps make it really comfortable to carry, even when it ’s fully loaded. I also love the multiple compartments — it ’s easy to keep everything organized, from my laptop to small accessories. The material feels durable and water- resistant, so I don ’ t have to worry about sudden rain. Overall, it ’s a stylish, practical, and reliable backpack that works perfectly for both daily use and travel.

I bought this item a few months back for my girlfriend. She loved the light purple color I chose as well as how comfortable it was. So far she has enjoyed it on multiple day hikes and loves how simple the organization is as well as the support while loaded up with layers, lunch, first aid kit, etc. She especially loved the ability to add her trekking poles to her pack while not in use and overall is happy with her Osprey Hikelite pack.

[ Love it!! Great quality and functionality- and with that a great companion for our hikes.
