a Whisker Dam, to prevent my 'stache from getting beer foam on it.... http://gearmoose.com/whisker-dam/ and these! MOLLE panels for the COOLER!!! http://gearmoose.com/orca-cooler-molle-wrap/
HA! buddy of me got me the same exact Whisker Dam for Christmas? a couple years ago. Can't say that I've tried it out. Maybe I'll include it with purchase to some member of the ESEE Order of the Beards sometime.
I'll give someone a knife if they buy the cooler Molle panel and attach it and the cooler to their load bearing vest....
