I tried the long T-short and like it. As my PI wear out, I'm replacing them with the T.

The fabric is a little thick, but it has a nice soft feel. Initially I found the chamois a bit much, but, as liza said, after you wash it a few times, it softens up very nicely.

I guess I don't find the fabric too warm, but it hasn't been that hot here yet. For me, sunscreens can also be oppressive so 4" more of fabric or 4" more of glue-y suncreen....its a toss-up.

The only down-side is that most casual shorts will sit on your legs now 4" above the Long T-Short tan line. But, despite massive amounts of sunscreen, I have also have a tan line at my wrists and the middle of my fingers. So now I have a visible one on my legs, too. It is just part of the cycling obsession, I guess
