What do you wear when you are swim training? (Page 4)

I don't understand why people train in jammers. If you actually spend a decent amount of time in a pool, you know chlorine turns your suits see through. Jammers are also "racing" suits. Or at least they were when they first came out and our coaches had us buy a pair.

I train in a speedo with a mesh drag suit over it.  The drag suit makes me work harder and doesn't cause me to alter my form. I wear it a) out of habit since my coaches had me buy them when I swam USS and b) because I don't care about the condition of my speedo underneath. My speedos however have deteriorated to the point where my only remaining one is a water polo speedo, which amazingly is still black.
