>>2313397Take a look at some ultralight backpacking blogs. You can cut a huge amount of volume with changes such as follows (listed from biggest bulk to least bulk):
Sleep system:
1. synthetic sleeping bag --> down bag --> down quilt --> lower temperature rating bag/quilt which you supplement with insulated clothing and a warmer insulated sleeping pad (sewing your own quilt can often help save material)
2. closed cell foam pad -->inflatable foam pad (Thermarest type) --> inflatable insulated pad (like Exped Downmat or Synmat), which helps you carry a lower rated sleeping bag
Shelter:
1. 2-man tent --> 1-man tent --> tarptent --> tarp (supplement with bivy for blown rain and the bulk is still really small)
2. using your hiking poles for a tarptent or tarp structure --> using the environment (sticks or trees) to pitch it
Food/Water:
1. active water filter --> passive water filter --> filter + chems --> chemical treatment only (does nothing for flavor, and takes time for it to work properly)
2. nalgene bottles --> combination of a water bottle from grocery store and collapsible water bladders
3. gas camping stove --> alcohol camping stove --> no-cook meals (i.e., not bringing a pot at all)
Packing:
1. external frame backpack --> internal frame backpack --> frameless backpack (requires you to use a closed-cell foam sleeping pad inside as a substitute frame)
2. individual uncompressed stuffsacks --> individual compressed stuffsacks --> single, large compressed stuffsack for all dry goods --> use a waterproof liner and your backpack is the stuffsack that compresses everything (counter-intuitive, but this way ensures the least wasted space)
Multifunctional gear, things like:
-poncho-tarp (rain gear, shelter and pack cover)
-hiking poles (hiking poles and shelter structure)
-hooded down jacket (use as both a jacket and to supplement warmth during sleep)
-ccf pad (sleeping pad and as structure in a frameless backpack)
Also, just packing less shit in general.
