In addition to the expanded apparel line, FootJoy is also bringing more socks to the table. Look for color additions to the crew -- I saw a pair of coral ones in Derek's van. Biggest addition is an all-new wool sock that we got to see and touch at the FJA Invitational. Really a nice sock, and will go head-to-head against Kentwool. As Chris G said, it's hard to wrap your head around wool socks keeping you cool and dry, but wool has exceptional wicking qualities.
Do you know when this new sock range will be available? If there are some great colours will there be any in purple or red? Lime green would be too much to hope for. How about teal? Coral sounds really good though. Did you get a glimpse of the range of colours in the back of that Van GC? Are they extensive.
Wool is a wonderful fabric, suits are great in wool, many people think wool is about warmth only, but it's much more versatile, ask any sheep.
