Here is what I am considering for a 3-5 day Alaskan solo summer hike next summer. Some of the gear I have, some of it I don't, some of it hasn't been released yet, some of it doesn't exist and must be made (ideally someone here will have a commercial solution, but I can make stuff if needed.)
Situation: Remote location, Day temps up to 75-80, Nite temps as low as 20, could get rain/high wind, could get lots of sun, there will be many insects. travel in various terrain, including exposed mountain ridges and thick alders. Possible fall down a scree field.

Shelter- I need a a shelter that can resist high winds, blowing rain and hordes of mosquitos. So a free standing tent fits the bill. The lightest free-standing tent I could find is the upcoming Tarp Tent Rainbow (look at the preview under Spotlites on BPL.com)
Sleep- There will be stream crossings and possible heavy rain. A down bag is too much of a liability in my opinion, and doesn't deal well with condensation either. So a synthetic bag is the choice. The lightest I could find is the upcoming BMW Arc Cocoon (on a forum thread, can't remember which one). This is paired with multiple closed-cell foam pads for flexibility and not having to worry about getting pads wet or punctured.
full rain wear- jacket and pants are good for above tree-line winds. the eVent jacket is breathable enough to be worn as a wind shirt over a light layer. the patagonia micropuff along with a synthetic balaclava will push the 30-degree bag to 20 at least.
Pack- I need a tough pack that can deal with sharp rocks and alders. McHale makes excellent packs, and so are the upcoming Bozeman Mountain Works packs (again, saw them in a forum thread).
Other- I like hose systems instead of bladders, primarily because they keep my hands free and don't require stopping to drink. I feel the need for lots of first aid and repair gear because of the remote location and the terrain I am traveling on. A fall on scree can easily break gear or cause serious injury.
Lighweight soft-shell pants and a long sleeve sun shirt are ideal multi-purpose apparel for both above and below tree-line travel. timberland shoes look like an excellent cross-terrain shoe for wet conditions. trekking poles help stabilize the shelter and provide additional support in wet conditions. a lighter and multiple knives are good survival tools.
Survival: this is gear that I don't even include in my weight totals. A PLB provides emergency last-case insurance: alaska is too remote to rely on conventional signaling means in the event of a problem. A survival kit that stays on the body all the time (along with the aforementioned knives and lighter and the PLB- in a waterproof case) provide more emergency insurance in case my gear gets lost.
Summary: Basically, I have selected gear to deal with temps between 20 and 75, heavy wind and rain, insects and sun. It must be durable to deal with scree and bushwacking. I erred on the side of caution and I could probably deal with colder temps than those listed. There is also a fair amount of survival/emergency gear because of the remoteness.
