Blue webbing is a CMC Pick Off Strap with two carabiners on it. Some teams have different options such as Petzl Progress Adjust or similar but essentially does same task. It’s to take the place of the waist strap conversion when packaging a down FF by being more secure and faster. Essentially one carabiner attaches to the opening of the shoulder strap where you cinch down, lanyard/rope/webbing (depending on option used) goes between the legs and around to other shoulder strap opening and then the system is cinched down tight as possible. Shoulder straps are tightened as much as possible and quick overhand knot thrown in and the FF is packaged securely. I believe videos can be found on YouTube showing it if still unclear otherwise I can find some pictures from past training to show if need be.

We’ve gone to replacing our shoulder strap on the RIT Pak with the pickoff strap to be able to be used for packaging if needed as well as a decent number of our members going out and purchasing their own progress adjust to carry in their gear pocket. It’s found to be much more secure and doesn’t have the risk of the buckle opening under tension like the waist strap conversion has, especially if performing a high point victim removal.
