> 3 dayThis backpack got me through a very difficult back packing trip. If your on the fence about spending this much a pack, just remember that your back will thank you for going with quality. Just make sure you get fitted for it at a place like REI before you purchase. Im 61 and the medium fit like a glove

> 3 dayThis is a lightweight large capacity internal frame pack for men. The pack is made of nylon and nylon dobby. Empty, size medium weighs 4 lbs 6 oz. The pack is loaded with pockets, top to bottom. The floating lid is removable and has 2 pockets; if you remove it from the main pack you can use it as a fanny pack. If you remove the floating lid, there is an internal flap (flapjacket) to keep rain from coming in the top of the pack. The main compartment of the pack has a sleeping bag compartment at the bottom with a removable divider. In the center front of the pack is a mesh pocket for carrying quick access gear (raingear, spare flipflops), with 2 more pockets behind it. The hip belt also has 2 small zippered pockets. There are mesh water bottle pockets on either side of the pack with dual openings, one regular at the top for vertical carries, and one angled so that you can grab your bottle (or whatever) with the pack on your back. The pack also includes a hydration sleeve and port that will accommodate a 3 liter water reservoir (sold separately). There is a heavy-duty carry loop on top of the pack, pole attachments on the straps, tool attachments on the main compartment, and removable sleeping bag/mat straps. There are also upper and lower compression straps. The pack is mesh-ventilated in the back, has a hip belt and a sternum belt with an integrated whistle. The internal frame can be adjusted for torso height and the hip belt for waist size. Zipper pulls are molded plastic loops. The pack is rated for 30-50 lb loads. The pack is backed by the Osprey lifetime warranty. This is a really comfortable pack for moderately heavy loads. It spreads the weight out evenly and suspends it to minimize uncomfortable contact points and abrasions. I found it extremely comfortable for multi-day trips with 40 lb loads. Much more than 40 lbs and the suspension felt a little mushy. Good reason for not trying to carry the kitchen sink. There are so many nice little details about this pack—from the easy access water bottle pockets to the removable floating lid. And the pack holds a lot, both in the main compartment, the back pockets, and the tool loops. The main reason I like the pack is the fit, though. With packs, one size doesn’t fit all, so this pack comes in 3 sizes, each with adjustments for torso and waist so that you can really get the fit just right. And once the fit is right, the load rides comfortably.

> 3 dayWell-built pack. I know several people who use this for extended hikes and group overnights, so I know the capabilities and durability of the Osprey brand. What is super-nice about this specific one —- it comes with a rain fly. The AG system is the absolute bomb. I will NEVER have a pack without the AG system. I haven’t been on a hike with this one yet, but I have used it for personal travel and it is unbelievably comfortable and roomy. I’ve “pre-packed” for a hike, and this holds my ORC 1-man tent, sleep bag, cook gear, food, clothing, bear bag, and survival equip all within the bag itself. The only thing attached to the outside of the bag is a camp chair, hatchet, and trek poles. Buy this bag... you can’t go wrong.
