He's swim-training for a tri and alternates these with his Zoot tri shorts (very thin chamois). He also has the Coolibar swim shirt with the slightly higher neck and thinks it's great.

we live in a warm climate so I didn't need a wet suit or shorts - and I've owned two other coolibar shirts and loved them so it seemed a natural to order these shorts - they are what I was looking for and have enjoyed them in my last few dives
