Fox Outdoor Products Rio Grande Backpack - Lightweight Hiking Backpack 40L, Water-Resistant Daypack for Camping, Travel & Outdoor Adventures

I have used this bag both for camping and lugging around audio recording equipment (max load approx. 40lbs). So far it has held up perfectly under both circumstances. The straps and back are both well padded, making this bag easy to carry around for extended periods of time. I suppose it goes without saying, but a 45L, the bag has plenty of space.
