I got the basketweave and basically agree with Fycus' impression; it is very light, textured, and a little bit crispy. The weave is deep with some khaki threads and is not captured well in any photos I've seen. It looks much better as a shirt-jac than a midlayer.
Tried this on today and was surprised to find that the Large fit best; the M had pulling in the shoulders when buttoned and looked too short (and I am already short). I now fit S, M, or L depending on the piece, so that's pretty funny (and I'm guessing XS fatigues would complete the set).
How loose is the Dayton? I'm always on the border with EG sizing (S in the CPO and Miner, M in most jackets and the Work Shirt). P2P/S2S measurements never seem to help because the cuts are so different.
