Wow what can I say about this pack. It is the best pack I have found for my build. I have longer torso than normal and it fits like a glove. So you can take the top off and it basically looks like the Vapor Trail. I lay my platy on top for easy access and its awesome. The side pouches for water bottles is used for rain pants, rain cover, headlamp and essential emergency stuff. My Zlite strap to the outside perfectly. My base weight is at about 14 pounds. There is so much space in tis pack so I pack really lightly and let my stuff spread out so the weight is even. I reccomend the Nimbus Meridian to anyone. The frame is really comfortable and the straps are interchangable as well as the waist belt. Dont think Ill ever hike with anything else.
