I'm looking to expand the room on my Warhammer to hold some bulky clothes and such for some later hunts this year and I keep arguing with myself over whether to get the spike duffel because it is cheaper and light, or the little brother so I have the option of using it as a day pack also. I can get the Little brother off pro motive for about $130,but they don't have the duffel in stock. Anybody have experience with these that might help?
