Well, really, this cat, Jeff, whom I met atop HalfDome last year, and we hiked up JMT a ways and talked about bpl before I was overcome with the weight of my traditional hiking and he streaked on ahead. (Hey Jeff!, if you're here.)
I was amazed he could do the JMT with such a small package. Anyway, looking at this picture later, (it's a Golite or GossamerGear?), the way it hangs back off his shoulders at a bad angle, and no weight on his belt, looks... uncomfortable, and, well...wrong.
Now I've got most of my lightweight gear for several week-long Sierra trips this summer. I'm ready to buy my first LW pack and have read virtually everything here. But I have serious reservations about carrying my pack like this for 6 days...
