I just received two swift speed cropped tanks in burgundy bay and white. I noticed a couple changes have been made from the old model to the new: added seam along the bottom, zipper pull is different, and the new version does not have the reflective dots. I haven’t taken the new one out yet, but they look to be otherwise exactly the same so I don’t anticipate any issues. I think I prefer the small zipper of the old version though.
