I've created some preliminary renderings of point of purchase displays. This is more of a brand theme excercise, and I've used the vest graphics to inform both the packaging design and POP. I'd decided on using a K-fold pouch for the vests since it's inexpensive and compact. We may have to do packaging in quite a few languages, and this packaging system would appear to be the best way to go.
UPDATE: I've just recieved the next set of prototypes, and it looks like I'll be able to keep the packinging as small as I'd hoped. The vest weight in the medium size is just under 2 oz (57g) -- exactly as expected.
