Arrio 22L Unisex Day Hiking Backpack with Ventilated Backpanel and Built-in Hydration Attachment (Reservoir Not Included), One Size Fits All, Empire Blue

Love the fit and feel, being 5'11" at 300 lbs this bag fits me perfectly and is way better for my size compared to the normal size packs. Straps are longer and more comfortable and the suspended mesh/vented back is so much better, I generate a lot of heat and this is a great option for me!

Used this backpack while hiking recently in the Alps. The pack was everything I hope it would be. It also worked well as an under-the-seat bag carrying electronics and other items (books, small pillow, snacks, etc.) needed for long flights.

I like this bag overall and have used it dozens of times. It's simple, basically a big compartment, great for layers and lunch. Took a star off only because although the mesh helps some, I found it does not help as much as expected or hoped for my wet back. The way the frame is it blocks some of the air flow.

I ordered this when my wife and I decided to start taking up hiking, for fun and exercise. I'm 6'1" and 330lbs, and this pack is perfect for me. took off the hip straps, such as they are, because they're thin, and arent really all that comfortable for me. otherwise, i strap it down, and haul the 3l water bladder, and a nalgene for my wife. By the time i am loaded up, it's about 10 lbs with the snacks, first aid and other little stuff that i take, but rarely use (be prepared...)

DISAPPOINTING FIT and NEEDS 1 More Internal Pocket

Pack was the perfect size for day hikes. The quality is really good.

It's more for women because of short not adjustable torso.Definitely not for men.

Initial use of the backpack for 4 mile hike was great. Especially love the "trampoline" back where air flow is enabled. Goodbye to the hot pack against my back! Definitely a big plus factor having that open area, which is why I chose this particular backpack.Love it for the life time guarantee also!
