I finished this one up the other day. I had sketched the idea a while back, and finally got around to making it. I wanted a larger volume pack that I could use this winter. I put a beaver tail on it to allow for expansion. I will be able to use it as a pocket almost, but I think it will add a bit more versatility. I went with dual stays inside. I decide to contour the bottom to tighten the load carrying a bit. I chose to eliminate the typical front-side panel seams to take away more opportunities for water to enter.
The lid is removable. I set it up so that I could have the top dry bag style, connected down to the sides (like an HMG pack), or with a lid. I like having the versatility to change the pack as I need.
The pack is made 210 denier laminated ripstop. The beavertail is Dyneema Grid from Dan Mchale. The bottom is DX-40.
