I'm 5'8 155 waist 30" and usually race somewhere around 145-147 and wear a small Orca. It fits perfectly.... maybe a tiny bit loose compare to my Synergy suit. Mine is the sleeveless variety though.

5'10", 30-31" waist, just over 150 lb race weight. Size M. FYI that is a swim skin, not a tri suit.

Hi there, if you click on this link http://orca.com/...kona-aero-race-suit/ and then click on "What's My Size" you can see the size chart for this suit, based on chest/waist/hip measurements. But I'd say if you're a Medium in most things then you'd probably be a Medium in this suit as our sizing is pretty standard. Hope that helps!

I'm a very similar size to you (5'7, 137 lbs). I have a size 6 Orca S3 wetsuit and also one of their 226 tri suits in medium and (for my body shape at least) the fit of the two is very similar.

My size 6 wetsuit is just "nicely tight" so if yours is "very snug", I'd say a small tri suit will almost certainly be too small; I tried a small one and could barely get my hips into it, so I'd go for the medium.

Just for context, I'm 5'8 and weigh 148 and waist is 29-30inch and wear wetsuit size 7.

Thanks all! I ended up ordering a medium.. Hope it fits welll cause all the sizes are backordered and I have Silverman next month!

Inventory came in today and the website should be "restocked: by tonight.
