This is my first review of a product ever...usually I don't feel strongly enough about equipment because I am so hard on gear that it never holds up. Such is not the case with the Airzone. I bought this pack about 8 months ago when I relocated to Southeast Alaska for work...(and play) This bag really, honestly has done it all for me. I use it as a duty bag, taking my overnight gear to and from work. The hiking around here is epic, and because of the weather the rainfly that comes with the Airzone is a MUST! It works great and stows super easy. I have used this bag to make a quick summit attempt of a peak in the winter,(the ice tool loops work great) countless hikes in the alpine, and slogging through muskeg, I have used it for super light overnighters, I have even been able to comfortably rig it to carry skis on a few off-piste days even though it isn't marketed as a ski bag. My only issue with the pack is that it took a couple months of scrambling and trail use to get used to the space between the bag and the user's back. Other than that, the hardware has held up to daily use, the straps are comfortable, and the bag itself is without rips or tears. I can't say enough good things about Lowe Alpine's Airzone. This is my first Lowe Alpine product, and if it is any indication of how their gear holds up, I am going to be a lifelong customer.
