The backpack version of the RIPT barrel — same gym-ready build, hands-free carry. Ideal if you're commuting to the gym or need to carry kit alongside a laptop or other gear. Compact enough to not feel cumbersome, durable enough to take some abuse.
Tom's take: The backpack format is the move if you're heading straight to the gym from work or training in the morning before the day starts. Keeps your hands free and your kit organised.
