I get that this pack's purpose is to be as light as possible, which it is. However, some design features could be a tad better. The top lid is nearly useless on it's own, so don't expect to use it unless it's attached. There is no rain cover, so you have to purchase and carry that separately. It has sleeping pad straps, however....the point of this pack is to be light; those using this pack for min. weight will also be sleeping light. Therefor, they are most likely not going to be carrying a closed-cell foam pad. My main dislike of this pack is that it is completely inconvenient to pack and unpack. You must remove everything to access and load your sleeping gear. I would rather forfeit the lower compression straps and have a zipper at the bottom to access my sleeping bag. Lastly, it's color options are both dark...one being black. The air circulation is amazing, but the black just sucks up all the desert sun and heat. A lighter color would be nice...for all pack models.
