I know that the J107 Dragonfly does. It actually has a pouch that is designed"ish" for optics. I carry my spotting scope, rangefinder, range book, shooting mat, PDA, Weather station, shooting sticks, bipod, and more in it. It has the ability to expand to as big as 7900 ci and compact as small as 2900 ci. The J34 is also a very nice pack with lots of room, that may work for you but not so bulky the J107 is designed for hike in hunts).
