Looking at the Sea to Summit day pack I’m drawn to reconsider my overnight pack again. What do I really need for an overnight….The 5 CsCutCordageCoverCombustionContainerThe Rule of 3’s3 minutes without air3 hours without shelter3 days without water3 weeks without foodSince the area I’m talking about is well traveled and limited to about a 12 mile loop not much can go wrong. But again as I consider that my last hike I carried bout 20 lb of stuff in my pack I think I can go lighter… simply put I only used a fraction of what I brought.hammock, straps, bugnet sock, tarp, stakes.poncholighterbug spray, sunscreenextra sockswaterwater filter and dirty water bagbear bag and linesnackstweezers, tape, gauze, Imodium, water treatmentflashlight with fresh batteriesI brought and did not use but good to havemosquito netemergency whistlesmall knifetoilet papermisc medssleeping bag liner depending on how wet you areanti bacterialI also brought but did not need:ultralight air mattressfero rod, frankly why bother either this or the lightersolo stove, too wet to burn tinder; food spoiled anywayvery light LED lightsAnd I brought but was a comfort iteminflatable pillowsit pad doubled as a floor matAnd I did not bringfuel stoveOne other luxury item was a handsaw. It just makes processing wood easier if you want a fire. This is a real saw and not a swiss army knife.Lastly I can cut the shelter weight in half with just a poncho, a bivy, and a small foam pad.
