I experimented with nearly equal-weight Polypro, Capilene, and Polartec.
The results were approximately as follows:

dunking wringing
Polypro 4x 2x
Capilene 6x 4x
Polartec 6x 3x

Polypro is definitely the best thing to wear under a paddling jacket
in conjunction with a wetsuit. Inside a breathable drysuit or drytop,
my recommendation is Polartec PowerDry, an engineered polyester
fabric.

Those are an interesting set of measurements. Makes me wonder whether
non-absorbing fabrics have been tried and rejected?
