Last June, there was a discussion of chaffing on this site, initiated by Tim Mattson.
I never expected, as a beginner, to encounter the problem -- but about 10 kilometers into today's 12+ km paddle, I did. I re-read the chafing thread and saw that Tim eventually solved his problem with an IR guard.
Not only am I a beginner, I'm an ignorant beginner. Could someone please explain what an IR guard is.
