Hi all. Going to buy a new base layer for this winter's base miles -- long distance, aerobic miles in temps from 30-50 fahrenheit. Gonna usually wear the base under a merino wool jersey. I like merino wool - warm, cozy, wicks well, and rarely needs laundering.
Any advice regarding these two choices? Ground Effects makes a merino/synthetic blend, and Hincapie makes a 100% merino. I'm not sure what the diff's will be(?) Advice?
