Most the maxpeditions will work just fine, as will man camelbaks. I own way to many day bags and just added a MC Camelbak Trizip since I wanted something in multicam but bigger than my TT operator pack for this years elk hunt since we are already getting snow it going to be a cold little outting. FYI just to let you know, its best to know that most the bags that will comfortable do an over night stay is ment to be hiked in, which will typically be a dual shoulder strap style pack, nothing wrong with a little jumbo or what not, but unless you plan to sleep under the star, eating 1 little meal, and have no sort of emergency kit, your pack will likely be 2300 to 3000 cuin (depending on insulation/ food/ comfort devices etc.), which is not going to sling at all.
