Size 6 is from an older batch of vests which was made from a slightly thicker fabric than the current vests and does not have the pocket.
Size 12 has a discolouration on one piece of reflective where it was overheated in the ironing process. Overall, it looks great and works the same.
Handmade, high visibility, reflective cycling vest. Size 12 is lined with mesh lining, allowing the vest to function like a bag, where you can fill it up with items, through a secret zipper in the side seam. Items such as a wallet, keys, bike lights, snacks, a bottle of wine, etc, can be placed into the front and back of the vest. Both made from breathable sports fabric.
