We'll all experience different clothing differently, so every opinion on "the best" is valid.As Jimmy mentions about if you cant wear an item more than one way you probably shouldn't bring it...
Something like Columbia PFG or L. L. Bean's Tropicwear shirts can be had in short or long sleeves, but the long sleeves can be rolled up and buttoned so they stay up above your elbow. Sometimes I dont even bother bringing a short sleeve shirt other than a tee.
3 in 1 cold weather coats, same thing. A nice fleece that snaps and zips into a quality waterproof shell, which itself could be worn alone.
For what it's worth we've ended up with Icebreaker socks and Craghoppers trousers and shirts. I find the Columbia material less "breathable" and the Craghoppers material better, particularly in hot/humid climates.
