Immersion Research Men's Short Sleeve Rival Jacket

Works great! Stays dryer than I expected.

The freedom from restriction of a shorty is game changing. It stays way drier than I expected. No latex to deal with, just neoprene. The material is light and seems pretty durable.

Comfy at 1500 meters high.

I was using a rashie and a neoprene vest but was still getting cold, in a tropical country but at 1500 meters elevation. I added this on top and was a lot more comfortable. Breathes well so I don't overheat and keeps a lot of the water out. Also improves the seal of my skirt with less water getting into the kayak as well during rolls.
