Are you washing clothes during the hunt? On 4-day trips, I take socks and underwear like you: one replacement set, and each set gets rotated each day. On the 10-day trip I'm about to leave on, I take more socks and underwear, but plan to wash them half way through the hunt. I've considered sticking to the 2-pair rotation theory and still washing half way through the hunt, but my hike in is short enough that I can easily carry an extra 2 pairs into base camp. Just curious; considering changing my routine; not suggesting you change.
I considered Rokslide's kill kit, but I already had too many of its components to justify. I do agree with their selection of products.
