The Modulus 55+10 L is one of 3 pack sizes that can be attached to the Modulus X1 Frame to create a system ideal for hunters who like to separate their retrieved meat. Most features of the Bison pack you know and love are included in this pack, including the 3D Front Opening.

The 55+10 litre size is perfect for overnight or short trips. With the Modulus system, you can leave the pack at base camp, hunt and retrieve with just the frame, and then reconnect the pack when back at camp.

Unlike other packs on the market, the Tatonka Modulus has been designed in New Zealand and tested to the extreme in New Zealand conditions. We have made multiple changes along the way to ensure the setup retains the comfort and stability (even with heavy loads) that our standard packs are known for.
