Golite Trek is a nice option. I even use it in winter because it is easy to tie on snowshoes, crampons or a tent. The outside middle pocket is spacious, but netting and, therefore, not water resistant. It has a daisey chain down the middle, but be careful in lashing things to it if you need to get access to the mesh pocket during the day as you hike. The mesh has a large opening (zipper) and is a good place to stuff a wet tent fly or tent. The side compression straps are useful if you need to add a pocket to the outside or lash something, like a tent pole bag, to them. The top pocket can be removed if you do not need the space. The top pocket, however, also doubles as a cover for the top opening. If your pack is full, the collar cannot be rolled, so the opening might not be totally closed at the top with just the drawstring. The pack has plenty of volume for your needs. (I recently finished a 5 day hike using the Golite Jam Pack which is a smaller version or clone of the Gust. It was jammed packed when I started out, so the Trek would make packing easier with more room to spare) Also, I do not carry a tent in 3 seasons, using either tarp or hammock. The hip belt fits nicely, is slightly padded and adjusts easily with a buckle arrangement to keep the long loose ends from dangling.
The bottom material is a lightweight cordua which makes it tougher than the rest of the pack material and less worrisome about tears when you set it on the ground.
The sternum strap on the Jam Pack is elastic, the one on the Trek is just webbing. I rarely use either. They have the adjustment straps over the shoulder. It has an inner pocket for a water bottle and hose opening. In short, I am a fan of Golite packs. BTW I try not to add things to the outside of the pack including the sleeping pad, either a thremarest or z-rest. I do add a small pocket pouch attached to the hip belt for carrying gorp, and a camera case attached to a shoulder strap.
