I have been to Hancock fabric every day this week. I was think rip stop nylon at first. Then canvas then some sportswear twill.

holy cow, so many options the employees don't seem to know anything about their material.

I backpack so I hope I can find a solution that does not weigh a ton. I want a winter sock that will work good at low temps. not necessarily below 0 but maybe single digits anyway. What material should I make it out of??????
