Size Guide

Due to the expandable nature of the FlashBk garment these sizes are
approximate as it is possible to expand or contract the garment to
varying degrees as required. 

The FlashBk is a unisex fit.

If you order from MotionFox but the size
just isn’t quite right when you get it – send it back to us and we’ll
swap it for a different size. We’ll refund your postage as well so it
doesn’t cost you anything to change sizes. It’s hard to tell what will
fit by just looking at a website so don’t fret, just order and if it’s not
the right size we’ll swap it out for you for free. No bother :-)
