This pack is too small for the serious trail worker. My 211 chainsaw (a relatively small size) barely fits in the holder. While the pack has many small pockets, it does not have room for the stuff a sawyer needs to carry in addition to the saw: fuel/bar oil bottles, water (at least a quart), gloves, chaps, wedges, first aid kit—not to mention lunch, extra torso layer, rain gear, etc. Pack is a bit too small for my relatively average torso (5-10, 200lb male)—when the hip belt is right, the sternum strap rides way too high. Zippers seem a little stiff, but hopefully they will loosen up a bit with use. There is a mysterious zipper that apparently opens up the bottom of the main compartment, but it’s impossible to get my fingers into the corner to get it unzipped, and I’m not sure what use it would have.
The pack might work for non-sawyer jobs, or quick trips in pleasant conditions, but the lack of room for bulky work items and the other stuff needed for a safe day in the backcountry is real drawback. This is an expensive piece of gear and I expected a little more thought would have gone into the design.
