I have been using a DD Commander for 3+ years, and I bought the Paratrooper for my teenage daughter. It has almost as much storage room as the Commander, and at a great price! We both like the large pockets on each side that fit a large sized hydro flask with ease. Might have to get one for myself, for when I want to pack just a bit lighter.
Only time will tell how it will hold up, but it seems plenty solid and well built.
