I have about a dozen packs made by various companies. Many of them are really good. I have 3 models of Sitka Gear packs, 2 Badlands, 2 Keltys, 2 Lowas, a North Face, a Gregory and an Osprey that are all outstanding, along with a number of others that are fair to good. Just about a month ago I bought a new Eberlestock X2 with the tubular steel frame and mesh back, and I got many of the accessory items with it, although most of those are not really necessary items. The X2 pack is "only" $150, which is a bargain when you compare what you get as opposed to other packs. The X2 is the most versatile pack I have ever seen because it can be used for everything from a real day pack at only about 1800 cubic inches up to a full bivy pack at double the volume, and for hauling meat or other bulky loads. It also allows you to attach numerous accessories from Eberlestock and many of the Molle accessories manufactured for the military or for other packs. The X2 is very well made and is comfortable to carry. It is my "best pack for the money", and I have some great ones to choose from. Second choice for me would be a Sitka Gear 32 pack (I also have the 14 which is on the small side), but it is more expensive and not as versatile or heavy duty as the X2.
