Mystery Ranch supplied the US military with patrol packs under USSOCOM contracts. The civilian 2-Day Assault is the same construction for 72-hour lightweight EDC.

Mystery Ranch was founded by Dana Gleason, who previously co-founded DANA Design and sold packs to the US military. Mystery Ranch continues that tradition — their NICE frame and YKK zipper systems appear in military-contract packs and in this civilian offering. The 2-Day Assault is the compact version of their military patrol pack: 27L, MOLLE, and built to take actual abuse.
Mystery Ranch's Non-Inventory Cranium Effector (NICE) frame distributes load onto the hip belt more effectively than most MOLLE packs. The result is genuine load transfer for a heavily loaded bug-out bag — not just shoulder compression. For a pack that might carry 35-40 lbs of kit, the frame system matters.
