[This review was collected as part of a promotion.] My wife and I have NRS Ion and Siren PFDs that we use for Hobie Cat Sailing. We wanted to get a spare PFD for when we have a guest. The Vapor has the same cut as the Ion and Siren (incidentally the Ion and Siren are the same jacket with the Siren just branded to be a women's model) with a few less features. The main difference is that the outer shell is a different material (I think the Ion/Siren are a rip-stop material while the Vapor is not), the I/S have a pocket on the front and a partial mesh lining. The one feature that we do miss on the Vapor is that the I/S have a pocket to tuck the excess shoulder straps in.
