For those who are interested, I also decided to test the water resistance of all the same fabrics. I rubberbanded the fabrics over the empty measuring cups and then let them sit (in groups of three) in the shower for ten minutes.
Uncoated 1.1oz ripstop: Predictably, the shot glass/measuring cup with uncoated ripstop collected about an inch of water, almost filling up the little cup. The fabric itself was soaked.
1.1oz Ripstop with DWR: Surprisingly (possibly), the 1.1oz ripstop with DWR was the most water resistant of the ripstop fabrics. It collected less than a quarter of an inch in the bottom. The fabric was wet.
0.9oz Ripstop with DWR: This one was the biggest surprise out of the ripstop fabrics. It took on as much water as uncoated ripstop and the fabric was wet. This surprised me, as this ripstop appeared to be resisting the most water when I tested it. The water visibly beaded up on the surface. I tried to be careful in positioning the cups under even amounts of shower, but the results of this and the fact that so much water was beading and rolling off this fabric make me wonder whether this one was hit by more water than the others.
Low-loft Powershield: There was no water accumulation in the glass with low-loft Powershield. However, the wicking, fleece side of the fabric was soaked. In a ten minute heavy rain Powershield might keep a person drier than ripstop with DWR, but I would imagine that anything under the fabric itself, like a base layer would get wet from the fabric absorbing so much moisture.
Fuzzy Powershield: Like low-loft Powershield, there was no water accumulation in the glass, but the fabric itself was wet, even wetter than low-loft Powershield. I think anything underneath this fabric in a short rainstorm would also get wet.
Gore Soft-shell: There was no water accumulation, but like the two variations on Powershield, the fleece (wicking) side of the fabric was wet.
Generic Soft-shell: There was no water accumulation, but like the two variations on Powershield, the fleece (wicking) side of the fabric was wet.
Gore-Tex 3 Layer Pro-Shell: There was no water accumulation in the glass and the underside of the fabric itself was totally dry.
Generic WP/B: There was no water accumulation in the glass and the underside of the fabric itself was totally dry.
