Used baby life jacket

I recently became an uncle of twin baby boys and the parents and I are trying to find some infant life jackets. Do any of you guys have any leads on some life jackets.

For buying new, Try BJ's wholesale or Costco. They seem to have Kidder brand ones in all kid sizes (and adults). They are neoprene which tend to be more comfortable for the infants in my experience (less fussy). We've had success with them (my niece and my cousin have used them, from infant and bigger)

Hope this helps.

We got one last year at Costco for a fairly cheap price. I think it was Bodyglove brand. It had the C collar and zipped / bucled in the front. We also bought a different one (cant remmber brand) that had all of the flotation in the front (besides C collar) and zipped from the back. My son liked this one much better that the body glove jacket. I think it allowed him to move easier.
