This is a wonderful pack - Mystery Ranch Pop Up 30L Backpack - Men's

The Mystery Ranch Pop Up 30 is the ultimate daypack for backcountry hunters who value agility without sacrificing heavy load-hauling power. At 30 liters, it provides ample, well-organized storage for a full day's gear, optics, and hydration while maintaining a remarkably sleek, brush-friendly profile. The real magic, however, lies in its innovative telescoping frame. In just seconds, the Overload shelf transforms this compact daypack into a rugged hauler capable of packing out heavy quarters with incredible stability. Backed by Mystery Ranch’s bombproof Cordura construction and micro-adjustable harness system, it carries punishing loads with surprising comfort. It is hands-down the benchmark for hunters who hike in light and plan to pack out heavy.
