I've had four WM bags, one with actual Gore-tex (20 years ago), one with Gore Dryloft and two with Extremelite fabric (my wife and I both currently have WM Versalite's).

My wife's girlfriend has a WM with microfiber.

I personally wouldn't bother with Dryloft, and would either get Microfiber or Extremelite depending on the model and what's available.

The Microfiber is the best of all worlds in terms of durability, breath-ability, and weight. I've talked with WM's owner in the past and that's his favorite fabric if that helps...
