The Stache can be rolled and buckled on the sides, for the hike up. Rolled and buckled on top, if you like it that way or if it's on the full side after landing and stashing. Or simply closed with the top drawstring, for the quickest and highest volume situations.
Don't piss your shoulders off right before you need them to fly your suit. The Stache's shoulder straps are made from a blend of air-mesh and mylar, and distribute the load evenly across their wide flat surface. Hydration system loops are located on the shoulder straps if you like to suck on tubes constantly during your hike. The waist belt is just a simple 20mm webbing strap - nothing fancy - and is removable for the hikes that you don't need it for.
The Stache has a smaller zip pocket for electronics or valuables, and a lightweight mesh pocket for water bottles or nuts and such.
The bungee system can be used to carry jackets and other lightweight stuff you need to have on the outside of your pack. The lines are long enough to route through the sides, or down the front, depending on where you want the load. Two rows of bar-tacked Dyneema runs down the front.
