What Wazzu said is a God's honest truth. Everything should be tried and tested before you head to Mt. Whitney for the first time.
And that means
everything - no matter how small. I once went up Whitney in a pair of convertible pants that I had not worn in months, only to find that the fly zipper was broken. No other long pants in my gear. Do you have any idea how distracting it is to hike a populated highway like the MWMT with your fly open the entire way?
