The Mystery Ranch Pop Up 38 Backpack features a pop up frame that converts this daypack into a load-hauling system for those shorter, successful day hunts when shouldering out the brutal weight is necessary for extraction. The frame features expandable pole stays that’s height is adjusted via flip locking mechanisms and an adjustable load shelf to put your game bags or any other overloads. These features allow the frame to quickly and easily expand and adjust to carry loads up to 80 lbs. The Pop Up 38 originated from hunters’ feedback wanting a bigger pack option on this game-changing frame series. It features a large main compartment which can be accessed via a top loading shroud or by the full-length side zipper. The two-part lid keeps key items within reach while helping to secure and protect spotting scopes and tripods stashed in the outer, compressible pocket (which is also perfect for tucking away a puffy or rain gear.) Dual side pockets hold trekking poles, water bottles or longer tripods and the Autolock buckles and compression straps throughout cinch down firmly, preventing slippage. The unique telescoping frame goes from low profile to maximized load lifting in seconds, and the Overload feature is ready for when the game is on the ground.
