Yep, love my old super daggy Bump n Jump.
These have a kite knife, enough flotation to help after a lung busting landing and certainly helps keep the ribs together after a backroll accidentally morphs into a, higher than kite, kiteloop.

This incident impacted so hard that the jacket dug deep into the water and became a temporary water collection anchor, shearing down one side as I was hauled off for the next impact! Bloody glad I had it on!

$10 for a stitch up and still saving my bacon. Cost me $90 second hand.
Bump n jump 8/10 for function but only 2/10 for fashion
