Part Number/Model Number Question

In looking at some descriptions on-line and reading some reviews, I noticed the model designation F-2X. Is this a model that is slightly larger than the F-2? I noticed this in a video clip from the PPA show highlighting the waxwear bag - the F-2 size and "once a bit larger".

Thanks.

Hi Mark,
There is an F-1X named "Little Bit Bigger" and an F-2 called the "Original Bag". The F-1X is just a little bigger than the F-2. Of those two bags, only the F-2 comes in the waxwear material.
