The list below is for backpacking trips where I don't expect to see temperatures much below 40 degrees. Here in the south, that makes it usable for most of the year.
The total packed weight is 6 pounds, 10.8 ounces.





A few notes:
This, of course, doesn't include the clothes I wear (smartwool LS shirt, nylon pants, cap, wool socks, merino underwear and NB MT101s). Nor does it include the whistle I wear on a lanyard, the lip balm and map I keep in my pockets and my trekking poles–one of which has a length of duct tape wrapped around it.
The one real issue I can see with the list is the headlamp. I recently ditched a Black Diamond Ion (1.1 oz.) in favor of the PrincetonTec. Most of my hiking is in the south, and the best times of the year to backpack are during the late fall, winter and early spring. Hence, not nearly as much light to deal with as those of you who hike in more northerly latitudes. Given that I have to grapple with the dark more, the greater output of the PrincetonTec is more than worth the weight penalty.
