insights & feedback
===========
The osprey pack is pretty heavy, 40 oz is a lot. Plenty of lighter options. A goLit JAM (with some trimming) is HALF the weight.
8 oz for a cook-set? What is in the cook-set, this is unclear. If you are solo camping, this is a LOT. A solo-mug is plenty.
The headlamp is a little heavy, and there are nice options at ruffly 1/3 the weight (the petzl e+lite is excellent)
Fire-steel – NIX and use a mini-bic, with paper book of matches as backup.
11 oz for a HyrdraForm 3L? That is way too much for something that justs holds water. A 2+ liter platypus is about 2 oz. Nix any tube and just drink from a bottle.
NIX the poo-shovel and just dig a hole with a stick or pointy rock.
NIX the iPod
NIX the screwdriver
NIX the GPS, and just use the map & compass.
Trim the first-aid kit. I bet just repackaging it in a ziploc baggie will save a lot of weight.
A thin plastic 1-liter water-bottle from the gas station weighs is less than a Gatorade bottle.
Just take the tall gaiters and leave the Dirty-Girl set behind.
Is the small BodyGlide mini-stick really 5 oz? Repackage it in a salve jar, and apply with your fingertips.
CHANGE your cook system to alcohol. THe min-fancy-feast cat food can is all you need. Much lighter than the butane set-up. Then you can NIX the fire starting kit, and just use a few drops of alcohol fuel.
No need for spare batteries.
less than 1 oz of Dr. Bronners is plenty, repackage.
REVISE the line titled "PPACK WEIGHT" to read "BASE WEIGHT" because the proper definition of PACK WEIGHT includes the consumables.

Okay, I know you said you want to keep the heavy filter –
– – – BUT – – –
I would advocate NIX'ing that 13.9 oz water filter. You can filter the brown water with a 0.5 kitchen funnel lined with a bandana, and then treat it with AquaMira drops. The waiting time is very short, and there is no taste issue. The time it takes to pump 3 liters is about all it takes to purify the water.
I have done a LOT of desert hiking, and I do it with only aqua mira and a simple funnel filter.
