Cool for you.....no wait "dry" for you. I love dry suit diving. Anything below 75f and I am going dry. Kinda hate to see it warm up. I have discovered that my face gets colder when the hood is not thick enough or properly fit for my face. I went through a number of hoods before finding one that really contours right for me. You are going to have skin exposure unless you go full mask or hardhat. I finally ended up with a 5mm DUI. Yes the lips still get numb but the cheeks are much happier.
