I dive as well as wakeboard and kiteboard. I'd recommend a Hyperflex playa surf jacket. Best $85-$100 you will spend. It's windproof and waterproof and will keep you warm. Make sure and get one large enough for layering, over wetsuit, etc... They make one without zipper for kiteboarding harness, but check pricing.

I noticed many of the DMs in Cozumel wear these on the boat during the trip home after the last dive.
