Patagonia Atom Pack
This pack is a bad ass small satchel bag. Not big enough for more than a day hike. But, heck, if you packed properly - you could probably stash enough for the night. Plenty of space and bonus pockets. Waist belt is simple, yet effective. The material is super heavy duty - making it a durable pack for any conditions. It sports side straps for easy packing of trekking poles.
