Teal -- the story a three zippered MAC

Izzy's Mom, do you know if you can double up the chain (thus making in shorter) on the 3 zip mac? I'm new to RM and have heard that some macs do this and others don't (not really sure what it is about some bags that don't have this capability). Thanks!

I will take a look when I get home this evening and report back!
