Received this product through The Pack, and wow. My conversion to Merrell is complete. Well, done, Merrell. M Connect, when not in huraches or completely barefoot has been a no brainer, but my outdoor ultra marathon attire has been exclusively Nike DriFit. Wore the opti-wick today, and the textured softness, great cut, and wicking of this material is the best I've encountered. If only we can get y'all to make a lined short out of opti-wick material with a 5 inch inseam, then that with Bareform shoes, the outfit would be like running in heaven.
