I have owned my Arc'Teryx Bora 80 backpack for over a year and am satisfied with the pack. It has met all of my expectations and then some in terms of durability, quality, and load bearing. I purchased the pack not for a desire to be ultralight, but for my job leading trail crews. I often have a huge load, well over 50 pounds, and I need a backpack that would handle the beating. I have also been using the pack on shorter backpacking trips where I was not concerned about the extra size and weight. It is an indispensable part of my collection of backpacking gear!

What do I like about the pack? The pack itself is of the highest quality. I have no rips, tears, holes or any other signs of wear. This durability is after I have slid the pack down a scree field in Death Valley NP, used it to carry various trail tools to job sites, and regularly used it as my checked luggage on cross-country flights. The attention to detail is what separates the Arc'Teryx Bora backpack from others. The quality zippers are just one example of that.

I find the large outside pocket extremely useful for keeping anything that I may need quickly or need to keep out of the main compartment; for example, a wet rain-fly. The 'brain', top compartment, is also large enough for my 'necessities'.

The most important quality of this pack has been that it performs exceptionally when loaded with a huge load. I can easily adjust the weight how I want and can transfer it to my hips without any problems. On a trips in the southwest US and due to water weight, I have carried 70-80 lbs as if it were only 40 lbs.

What don't I like about the pack? Not much really. I never use the side zipper. The shoulder straps and hip belt are a bit stiff. It is heavy, but that is expected and needed for a pack of this size and durability. Price. All of my complaints are relatively minor in my opinion.

This pack has seen some beautiful places... Lost Lake, Chugach NF, Alaska...
