Tri Sports Bras?

[KSH]

Well, you need to find a tri top that provides support, without an extra bra on underneith. You do not want to be swimming with extra drag involved.

I have 2 different tri tops... one being like a small sports bra and the other a full torso top. Both cause drag while swimming.

My favorite sport bra ever is a Moving Comfort "Fiona". It's wicking and reins my 36DD's in comfortably. I am not squashed flat and while there's movement I don't bounce. It also has adjustable straps. They are velcro so I don't know how they'd hold under water-you might have to fit and sew them permanently?
That said, it's not a swim top. I'd say to try your local tri outfitter but the best one around here is run by men who do an amazing job of fitting shoes but have not a clue about bras. Most of the shops just assumed I'd be a large which is far too large in the band.
For the info I also liked title9 but I went local to make sure I got the fit I wanted.
