The Skycrane II is a modular, load-bearing system consisting of three primary bags: The base pack, the removable Little Brother, and the MultiLid. A completely scalable system, the Skycrane II is built around a base pack that employs our patented Cam Expansion System. Scale all the way down to a fanny pack with the MultiLid, quickly unzip the Little Brother for a lightweight reconnaissance or assault pack, or up to a large freighter ruck, the Skycrane II can carry whatever your mission requires.
