I'm an avid backpacker who has been working in the wilderness industry for years and gone through many backpacks, including; EMS packs, Gregory packs, Kelty packs. This is the best pack I have ever owned. I've put about 800 back country days over about 3 years and it's hardly worse for the wear. This pack will carry very heavy loads comfortably and packs down small enough do be used for short weekend adventures as well. The waist belt and shoulder straps are very comfortable and easily adjustable. The waist belt can be heated and formed to custom a person's waist. This pack is very durable. It has a lot of good pockets for storage all around the pack. Lots of cinch straps and places to strap gear on the outside. This is all around an awesome pack, well worth the money, I plan on putting another 1,000 days at least on my pack.
You can tell Osprey put all their design experience into this pack. This pack is a dream for heavy loads. With the custom molded hip belt and the great lumbar support, the pack locks to your hips with no rubbing and perfect weight transfer. The pack itself weighs slightly more than the MH BMG 105, but has better storage and organization options. I especially like the large side pockets on the hip belt for easy access to a camera, GPS and snacks. The double top pockets and double front pockets are great for organizing gear and provide easy access to essential gear without having to dig through the main compartment. This is a solid pack for long trips with heavy loads.
