So, I was planning on doing a completely separate batch of gear reviews, and I will do so sooner or later (maybe today. Who knows?) but right here I'll echo some of what BMW-K just said.
The two of us were dressed similarly, with the Poseidon suits (pure awesomeness) and BMW-branded Widder vests. Mine isn't quite as old as his, though. I got mine in 2005, so it's only eleven years old. Still works extremely well, and just absolutely does the job. You just can't go wrong with either of these two pieces of gear.
