Hi everyone! I could really use some advice on pack size (Literage) as I am in a situation that isn't super straight forward.

Currently by taking LxWxH of my current items, I come out to a generous 45L. This doesn't include clothing, rain gear, or extra layers. Food, or toiletries. I figured, I'd add 10L for that space which puts me at 55L.

But, here is my situation. I do more winter hiking and backpacking than anything else, and I am planning on hiking a longer trail (100 miles) over 6 days in the fall / winter this year. This trail is remote and doesn't have any great resupply points for the direction I will be going. So it is very likely I may need to carry 6 days of food with me.

This makes me debate going for a 65L pack, vs a 55/58L pack given all the food I will need to carry, and the general bulk of winter gear too...Does anyone have any advice or experience on this??
