Good question. There's still some details I'll have to figure out, but there are three aspects to take into consideration, it's just a hike, it's a longer distance than I'm used to and it's in fall where temps might dip below freezing. So I'll bring my 3-season gear + undetermined amount of food. I've been out up to -13c with the gear so the temperatures should be fine

• Water
  • BeFree filter and a 3 liter bottle for it
  • A separate bottle for drinking
  • Purification tablets in case the filter breaks
• Food
  • ??? I'll have to figure out how much calories I need on a hike and multiply it by the days we're out
  • Either a gas or wood stove, depending on the weather
• Sleep
  • Eno doublenest hammock + eno bugnet + dd underquilt + dd superlight tarp + suspension + ropes
  • 3 season sleeping bag
• Clothes
  • I would normally bring only extra socks, but maybe this time extra underwear as well
  • Probably an extra set of clothes, separate from the backpack so that I can shower after the hike before the drive back home
• Hygiene
  • Toothbrush & co
  • Dish brush & co
  • A ton of tissues ( https://www.verywellhealth.com/runny-nose-in-cold-weather-83155 )
  • Hand sanitizer
  • Toilet paper
• Health
  • First aid kit
• Misc
  • Power bank
  • extra shoes
  • Knife
  • Lamp
  • A thermometer
