How do you calculate your official pack weight? I've seen many people refer to it as their base weight…in other words the weight of everything without food and water. Is this the correct terminology for weighing your pack prior to food and water? The reason I ask this is because I am curious to know if the clothes you are wearing count towards your pack weight? When an ultralight backpacker states that he or she is carrying a 5lb pack, is that to say that he or she is not counting the clothes and boots they expect to wear into that figure?Jun 23, 2011 at 4:15 am #1752384

Base weight equals weight carried in pack minus the consumables.
Skin out weight equals everything carried including the clothes worn.

"Base weight" is primarily used for the sake of comparability. By leaving out consumables, the base weight number stays the same regardless of length of trip, whether overnight or ten days. You can, of course, cut total pack weight by taking less food (or, better, more calories per ounce of food so you can take less ounces without starving), picking a route where there is a water source every mile and no need to carry water, or reducing fuel needed by taking more cold meals. Base weight, though, is where most of us do the major trimming.
Not to be forgotten, though, is the fact that your feet and knees have to carry everything on your body, whether it's your pack or the clothing you wear. In other words, skin-out weight is, in the final analysis, your most important item. Interestingly, my two most significant weight reductions in the past few years have been in skin out weight, rather than pack weight. I switched from boots to trail runners and from aluminum trekking poles to carbon fiber. Both changes significantly increased my comfort even though they had no effect on base weight!
Also, remember that your clothing system includes what you are wearing. The clothes you wear should be analyzed as part of your total clothing system to avoid duplication–or gaps.Jun 23, 2011 at 12:25 pm #1752505
I'll go you one better: For many (but certainly not all) of us the cheapest most effective place to reduce weight is "skin in".Jun 23, 2011 at 1:45 pm #1752537

I like the way you defined base weight. It is something that always remains consistent throughout all types of trips regardless of length or duration. Therefore, consumables would not be factored into this figure since the weight of items in this category fluctuate as you proceed forward in your trip. Fantastic explanation. Thank you very much. Now I gotta figure out how to do some trimming ;)
