From the Masters 2014 Edition Fast Jacket XL, SKU OO9156-27. The only SE Fast Jacket to come with its own SE switchlock microbag, at least that I am aware of. All other SE Fast Jackets look like they came with a non-switchlock (pouchless) SE microbag. Note: I was crazy lucky to have run across this for sale by itself, as reportedly there were only 50x units made. That means one of the 50x 2014MEFJs is sadly missing its pouch! Haven't seen another for sale since. Doesn't mean they aren't out there, but probably not for cheap, at least cheap for a single microbag.
