Bought this pack because it reminded me of the Alice/garbage can style pack. The option to empty the middle and turn the sides into a daypack was another great factor. Rucked this thing on a Duplex Lite twice now (only had it 2 weeks). I have to say this is one of the most comfortable packs I’ve ever used. All of the weight is on the hips. The straps keep the pack tight to the back to prevent being pulled off balance while limiting the amount of weight on the shoulders. The pack itself has generous space, and the side pockets are perfect for carrying my tent poles and stakes, a small machete, small cook kit, first aid, poncho, rain pants, 1500ml Nalgene, Grayl Geopress, and small do-dads/lights. The central pocket is massive and holds my tent, sleep system, extra clothes, hygiene kit, with ample room for food and more water if needed. Even with the extras, there would still be space left over. This would be “the pack” if the Marine Corps did things smarter not harder.
