Ooops. I only have one water bottle, the other was in the list by mistake.
That water bottle had thee main purposes: 1) store 1 litre of water, 2) act as an integral part of the water purification system as it screws directly to the water filter, 3) is opaque enough that it turns into a great light diffuser lantern when the flashlight is dropped into it. But, I was thinking about the whole water system being too heavy. So I experimented and found that my pump (MSR Hyperflow) wedges directly into the mouth of a platypus 2L bottle, though not by design. Thus, the waterbottle is eliminated all together. A filled Platypus waterbag works almost as good as a bottle lantern.
I am kind of bogged down by the first aid kit, by my training, by my companions expectations, and by my experience with what can and does go wrong. I am a physician, and just released from the Canadian Forces where I was also a physician. My philosophy of preparedness really weighs me down here. The FAK is broken into 3 paradigms: 1) stabilize the "reasonable to occur" conditions that immediately threaten to end life or limb, 2) temporize the "reasonable to occur" conditions that threaten to end the mission, 3) alleviate the "reasonable to occur" symptoms that threaten to end the fun. But, every couple of weeks, I open up the first aid kit and try to lighten it up. If you can believe it, I was once expected to carry two backpacks. One with my personal gear, and one with approximately 30-40 lbs of medical equipment/supplies. Its a struggle, but I am working on getting this lighter.
I have lost lots of weight recently, so I am hoping this might help me reduce my shower kit, but I have to test it first. There is 20 grams of vasoline (eczema, not other stuff that your imagination is dreaming up :) ), 50 grams of baby powder (the crotch rot that heavy guys who walk many miles in moist conditions get (maybe that will be a thing of my heavier past). I can probably also get rid of the deodorant stick (42g modified ministick) for the trips where the wife isn't present). Maybe get rid of chapstick as well (15g):
Towel 77g, facecloth 6g, soap/mirror 33g, toothbrush 20g, toothpaste 30g, tacrolimus (outright temporary cure for eczema around my eyes) 3g, bag 7g: that gets me to 176g.
The repair kit....I will have to itemize that and get all your opinion on that. This kit has saved my bacon many times, usually with the items in it I thought I needed the least: hiking pole repair sleeve salvaged into kit from previous broken hiking pole (that helped me repair a second broken stick that helped me offload an injured knee and properly set up my shelter), extra hiking pole cage that was pulled off and thrown down a canyon by a agave plant in the grand canyon, rebuilding a boot nearly completely eaten by a porcupine that acrobated into my tent vestibule while I slept one night (Rockies). I may need some more balanced vision on this, as mine is getting clouded by paranoia.
Those socks are also a consideration for the chopping block. They are the only remnant of my old military kit I have left. And, they are heavy. I am in the market for some lighter, dual layer system of socks (really helps with the blisters). Any suggestions?
