I'd like to have a low cost sleeveless suit for swims that are borderline wetsuit legal. I love my Desoto T1, but it gets pretty damn hot in the higher temp swims.

Any reason to think either of these options would fit better than the other, let less water in around the arms? A speed vest is roughly 200 US I think.

I can get a low end Xterra Volt sleeveless on sale for about 110 US shipped...

Thx!
