Coat

Are you not intending to shower and/or dry off and change before going back home again?

E.:

I'm confused. Are you concerned about having a coat in your locker at the gym or pool and it getting chlorine on it or are you planning on jumping out of the pool - not showering or rinsing off and just leaving?

if you are worried about chlorine from the pool while a jacket is in the locker? Don't. You will be fine.

If you plan on NOT showering or toweling off when you get out? I would STRONGLY suggest you reconsider your "routine" and take a shower at the gym or towel off before you get dressed and leave the gym...

Personally? I would take a shower and get dressed before I left the gym.

I'm confused. Why don't you dry off with a towel before you put your coat on? Anyway, in addition to Under Armour and North Face, try Lululemon.

I don't understand. Maybe I'm missing something. I go to water classes and then back home. I don't wear my swimsuit outside the gym. It's not very comfortable not having anything under me on the car seat.

I don't get why you'd need a coat to fit this requirement. My mind can't fathom......lol.

Try Underarmour or The North Face. Both will keep you warm and toasty if you are planning a quick exit from the pool to home.

Hmmmm...I would probably dry off, then change back into my clothes before putting my coat on.
Or are you thinking because your coat will be near a pool it might get wet?
You could always throw sweats on over your suit.
