The Porter 46 Travel Backpack is Osprey's maximum carry-on, and it's completely convenient for any vacation. The ErgoPull hipbelt and padded shoulder straps are stowable for compact convenience, and there are multiple grab handles. The padded organization pocket features multiple sleeves for laptops, tablets, and work documents, and the vertical front pocket is perfect for additional layers in case the airplane gets cold. The Porter also features attachable straps for Osprey's Daylite Daypack, and StraightJacket compression straps keep the load steady when you're on the go.
I own some hand tools, but Osprey Packs Porter 46 Backpack - 2807cu in is my most favourite.
