My insights:
=========
Upper Nylon SS T-shirt 8 – want to find something lighter but still nylon
extra synthetic T-shirt 4.9 – want to find something lighter but still nylon
– – – – – – – – – Two SS T-Shirts? Why? NIX one of 'em. It doesn't matter about the weight, because its a worn item.
dri ducks rain jacket 5.6 – not for rain but as long sleeve layer, needed?
– – – – – – – – – These are great. Totally NON-durable, but super light and very breathable – Be careful, they shred EASY.
– – – – – – – – – No long sleeve layers except the Dri-DUcks jacket? Wow, I would advise SOMETHING a long sleeve synthetic top of some sort.
equinox poncho 7.7 – as rain gear and extra rain coverage for tent
– – – – – – – – – Poncho AND Rain Coat AND a tent? Not all three. Nix something.
Lower Zip-leg pants 6.4 –
legs of pants 4.1 – not sure if pant legs are needed
– – – – – – – – – Use the dopey pants that come with the Dri-Ducks jacket. THese are fine. Light, and very breathable.
underwear x2 2.2oz
– – – – – – – – – Two of 'em? For a two night trip? One is fine.
slumberjack pillow 7.5 – modified from 12.5…LUXURY ITEM!
– – – – – – – – – THe BPL 1.1 ounce Flex-Air PILLOW is a LOT lighter.
tarp-tent rainbow 34.7 – plan to get tarp-tent sublite sil in the fall
– – – – – – – – – That's a lot for a SOLO tent. Just use your PONCH as a rain cover. Add a mosquito head net if you NIX the tent.
pack liner – trash compactor bag
– – – – – – – – – Go to the grocery store and get a trash COMPACTOR bag. THey sell 'em in a box of 5. This will waterproof EVERYTHING inside your pack.
stuff sacks 3.7 – for sleeping bag, toiletries and food
– – – – – – – – – Too many. If your pack is lined, you won't need any of these. Just food. Use a zip-loc plastic baggy for toiletries.
sunscreen 2 –
– – – – – – – – – 2 ounces it TOO much, go down to under an ounce. Re packaged into a tiny bottle.
bpl folding razor 0.27 P B need to buy
– – – – – – – – – Just get a single edge razor from the hardware store. Make a little folded cardboard holder.
1 liter bottle 1.6 –
Water 4 liter platy tank 3.8 – only used in summer
– – – – – – – – – What??!?!? a FIVE LITER capacity??? No WAY! That's almost too much for the Mojave desert! Just take a second soda bottle.
