Mr G wrote a review of GoLite Wisp Windshirt - Unisex on December 7, 2004
I've been very favorably impressed with the function of this shirt. It compresses down so small it fits into virtually any pocket. It doesn't breath as well as a non-treated wind shirt so I've felt a little clammy on aerobic hikes, but by that point it's usually time to take it off because of overheating. The most impressive attribute has been the water repellency. While mowing the lawn (2 hrs on a riding mower in a constant drizzle) not a drop came through the shirt but my supplex pants (no DWR) were saturated. I've yet to wear it on a rainy hike so I can't say it's been thoroughly tested yet.
