-Trevor, what are your expected lows? I am just wondering if the Icebreaker and TNF T-shirts are going to be provide enough warmth for the overnight lows and the early mornings?
-If they are warm enough, then I would wonder if there is a need for rain-pants-- since it would be a warm, humid rain almost? You're shorts should dry out in no time and your legs shouldn't get too cold either. I also do not see a warm hat, gloves on your list, and you are sleeping out with just a quilt which would support the conclusion.
I might even consider switching them out for some light-weight (Capilene 1 or 2 type) bottoms instead, or forgeting it altogether.
-Are the gaitors needed? You could take an ounce or so off your feet there.
-Have you consider dress or ankle socks for a 2nd pair? You could save around an ounce.
-If the temps are warm enough for little insulation, do you need two sleeping pads in July? You also have your pack to put under your legs if need be.
- I would nix the pillow, but it is personal preferance.
- I am not a fan of the Caldera system-- too heavy and too many pieces, but if you like it and it works for you great.
- 0.1oz of Dr B's seems awfully light for hand washing and cleaning teeth for five days.
-TP could be nixed, personal call though.
-Do you need your wallet+licence+CC+Cash for a five day section hike? Save 0.5oz
-I would nix the umbrella-- 5.5oz is a lot for such an item.
-Cell phone, for five days I can get by without music and books.
-bug protection is also a little on the light side at 0.1oz
