Best Backpack I've Ever Had

    I love this backpack. It can be small or surprisingly big when you want it to be. It fits great. Black Diamond really put some thought into this pack. All of the features are simply convenient. I mostly use this pack to carry around my climbing stuff. It works well for back packing too. I would not, however, recommend it if you are going for a long trip. One or two nights is all a minimalist could handle with this pack. It is simply not big enough.

    Jamaica bound

      This is a good lightweight pack. It meets airline carry-on requirements. It just went with us to our trip to Jamaica, it held enough clothes for a week. My only complaint is the top loader and no additional pockets, it's annoying to access anything unless you pull everything out. Other than that, really lightweight, durable, and did the job.

      Black Diamond Axiom 30 Backpack

        The Black Diamond Axiom 30 Backpack is exactly what I want in a technical daypack - it gets small when I don't need space but easily holds enough for a light 1-2 night trip. The back venting works well as I took this on a hike from 45 degrees and raining to 80 and humid and didn't end up with a wet back. On the same hike my gear stayed totally dry inside the pack. The shoulder strap system on the pack really becomes noticable when you load it up past ~20 lbs and adds comfort to the pack. The only qualm is that the lid attachment system is very tricky to take on and off of the pack.

        The feature that sold the pack for me is the strech pockets which can hold a ton of stuff for quick access. I was glad to have them for rain shell storage - a much better solution than my usual draping the hood of my shell over the lid of the pack and having a long train to deal with. Bottom line is this pack will do it all and can get very small or surprisingly large when you need it to.
