I'm fairly new to ultralight backpacking, and I've been trying to look for the following information with not too much luck.
What is the longest -AKA how many days- can you go with no replenishment before you cross over the line of ultralight backpacking? For instance, is it possible to comfortably hike for 10 days with everything you need -water & food- on your backpack and still call it ultralight? I'm wondering at what point food and water is so heavy that it can't be called ultralight anymore, or can it?
If you have any examples that includes gear list with food and water, it'll be helpful.
Thanks for your help,
