Or course. We each carry things that we don't "need" and add weight to our packs. My wife carries an extra foam pad, because she likes the extra comfort. It weighs 12 ounces. I carry fishing stuff, about 20 ounces. And we both carry a pair of Crocs that we wear crossing streams, and around in camp like camp slippers.

If we were totally dedicated ultra-lighters, we would leave all that stuff at home. And we would be less comfortable, and less happy.

Hike your own hike.
