The Base Camp is 40% larger than the weekend'r and suited to hold more gear for the longer stay. We pack these full on our fishing trips or longer camping trips. Holds just about everything you'll need. Made from marine grade PVC which keeps the moisture and inclement weather out and your gear protected. End pocket is sealed from the main hold and large enough to stow boots or an extra pair of footwear. A side pouch zippers tight for phones and wallets and chargers. The top access panel extends past the zipper channel to keep gear dry in the main stow. Bottom fitted out with a tougher outer layer skin for the rub. Inside you'll find a mesh pouch for all the toiletries. Back pack straps and hold straps throughout make it very maneuverable and carried in multiple configurations. A real stand out.
