This pack is perfect for a lightweight backpacker from anywhere from a weekend to a couple week trip. The side access to the main compartment is awesome. Suspension system couldn't be more comfortable and keeps my back cool!

    I recieved my backpack recently,I'm very satisfied with it. It's great, but I think it will be more useful if it could provided more instruction about the backpack.,thus I could learn more about how to use it.

    I've taken this a couple hundred miles on the A.T. and in coastal/beach environments. It's a beast. Super durable and a great back. I really like the pockets on the waistband, and the accessibility pouches on top and side. I wish it was less weight, but it's a trade off in price and durability I think.

    I am writing a review after using this backpack in a week-long trip. First and foremost, I was looking for a backpack - big enough - to carry on a plane overhead compartment. Having read limited reviews on the ability of this pack to do that, I was pleasantly surprised to accomplish that. Big plus there!

    Everything else about this pack is top notch - the ripstop nylon seems very sturdy, as well as the zippers and re-enforcement clips. The only reason why I did not give it 5 starts is its lack of a pocket on the underside of the top compartment. That pocket could be relevant to deter water, or to store documents in a more secure manner. Most other packs that I compared it against (in stores or while looking online) have a pocket there, including the same-year Z35 that I saw in a store. Other than that, I am very satisfied with this pack so far.
