While this newest model shares the name with the older Bora line, it has several significant updates over previous models, with the most notable being lighter weight and more weather resistance - all while continuing to upgrade the Bora's famous comfort. This most recent model specifically replaces the older Altra line of packs, utilizing a similar design and several features, along with a few upgrades.
Compared to older Bora model and the Altra, the newest Bora features a vastly improved suspension that was among the most robust in the review. Improved foam padding in both the shoulder straps and the hip belt that was top-notch. What sets the Bora AR apart from other models that are currently available is its AC² fabric, which made it the most weather resistant in our fleet. The Bora is a great all-around backpacking pack that is packed full of features. It's one of the best overall packs, which is thanks to its high level of comfort and excellent suspension system. Its downsides are that it's of average weight and it has an expensive price tag. At $550, it's $200 more than any other pack we reviewed.
