Sun block won't provide any protection against the heat. It only provides protection against sunburn.
Cool, I got a 100oz water bladder. Only thing it can cause some neck tension. Oh, and I tend to drink to point that I need to urinate urgently when there's no restroom in sight, but you made some good points about how to use a water bladder.
Okay, can you explain that bit about hot days having two dangers? the heat, itself, and sunburn? Sun block only works for sunburn, so what do you do to protect yourself against heat stroke?
