"The Osprey Exos 48 continues to be our favorite a reasonably priced pack that still scores highly in all metrics. The Exos is by far the most affordable, versatile, and widely available option out of all of these reasonably specialized packs. The feature set is extensive and allows you to pick and choose which features are best suited for your use. The pack is comfortable whether you're carrying 30 pounds or 10; though it is a bit heavier than most in this review, it makes up for it in comfort and ease of use. Also, it is still much lighter than a traditional full frame pack. For folks who are new to ultralight travel in the backcountry and are still transitioning from a full backpacking kit, the Exos is a great option. It is also a reasonably priced option and is easy to obtain. This pack is one of the most popular and widely used packs out there for lightweight backpacking use, and for a good reason! If you are looking for a lighter model that still has the same great suspension and ventilation of the Exos check out the new Osprey Levity 45, which is much lighter. But, if you're relatively new to ultralight and lightweight backpacking, or simply want a pack that performs incredibly well for medium weight loads, the Exos 48 is for you."

Fit is the key to pack performance. Take the time to get it right. Most Osprey packs are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine (as shown in the picture below) from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).
