It might sound stupid but as some of you guys here save weight pretty much everywhere, did any of you think about cutting his/her hair to save the last ounces? I guess depending on the haircut we are talking about serveral hundred grams...

(And no, I have no plans to do so, but it just came to my head ;)

I have my hair cut a week before hikes because that makes my hat fit best.

A little length is warmer and provides some sun protection. Longer is harder to keep clean and takes too long to dry.

Much more complex than just weight.

Years ago when I was just looking into getting my pack lighter, I went to the local outfitters and they told me to talk to some guy "Chris" on the weekend, as he was an ultralight fanatic. When I finally met him, he was a shorter fella with a seriously huge set of dreadlocks down past his waist - he must have been growing them for a decade. Months later I went back to ask him about hammock camping, and he had shaved his head to the skin. I asked him why...and you can guess what his answer was...
