I got this specifically to provide a little extra warmth for snorkeling and it was perfect. Excellent fit, no bulk, no chafing, no noticeable unwanted buoyancy. Just that little extra warmth.

a quality product, well made. Good fit, would recommend to anyone.

I previously reviewed the size Large.  I just got a replacement size XL, and it fits much better.  Here are the actual measurements of the XL (lying flat, not stretched):  chest 42", waist 35".  Because I had to go up a size, it's a little longer than I'd like it to be.  I don't have a non-neoprene Dakine rash guard to compare it to, so I don't know if the tight sizing is unique to just the neo-insulator or Dakine's sizing is simply wack.  I do notice the neoprene panels (the black parts) aren't as stretchy as the lycra (gray) parts, so maybe that's the issue with the size chart being a size too small?  At any rate, my advice is go up a size from what their chart says - and even then, expect a wetsuit-like snug (but not uncomfortable) fit.  I'm happy with the quality, so if Dakine would just properly label the sizes (and maybe shorten the length), I'd give it 5 stars.

Nicely made hybrid between a rash guard and a neoprene jacket.  Would have given it 5 stars but Dakine's size chart said I needed a "Large" (I'm a 42" chest, 35" waist, 40" hip). However, It was too tight across my chest and I could barley zip up the back.  The actual measurements of the size "Large" shirt are 38" chest, 32" waist, 34" hip.  Granted, it's supposed to be a snug fit, but it shouldn't be so uncomfortably tight.  Sent it back and am waiting for an XL; I'll post the actual measurements of that when I get it.

ordered it in my size but fits really snug.
Insulating panel holds the extra flesh in so even though snug,
you look good.
