The Montrails are the Wildwood TRs - they don't retain water much at all. The Ventilators I hadn't done water crossings with, but they probably have similar properties in the non-Gore version - very light and breathable. My only quibble with Ventilators vs. Montrails is the sole - the Montrails seem to protect the bottoms of my feet better, I don't feel the rocks in the trail through them as I do with the Ventilators.
