Subject: RE: Ironman Coeur d'Alene : Official ThreadHi! In response to the question about neoprene caps: I would definitley use mine in water under 60-58 degrees, as well as ear plugs (I always wear earplugs anyways ). I bought mine last year for IMSG, but didn't use it there (water was low 60's ). But I definitley used it here at Lake Mead from February to April, when temps were mid 50's. |
