Awesome pack with way more than 40l - Black Diamond Speed 40 Backpack

With it's internal drift collar, this pack easily has 60+ liters of storage, but you can strip it down to a super light wieght peak bag that weighs nothing and compresses down to school bag size. All the details are top notch: from the super durable fabric, to the tuck away rop carrier. The Ergo belt and shoulder straps are amazing as well, no restrictions in movement and a super stable suspension
