I have a HHULB and love it. I also have a 10 ounce Speer type for winter use. I am more comfortable in my Hennesy. I am considering an HH Adventure Racer for summer use to reduce weight considerably (1 pound less than my HHULB). I know that the Adventure Racer is not recommended for general backpacking but I only get to do one or two week-long trips a year and a few weekend trips throughout the year. I am very easy on all my gear and take very good care of it. I am 5'9" and 160 pounds so I am not too large for the AR. It seems to me that adventure racing would be tougher on gear than backpacking. Has anyone here used the Adventure Racer and if so how did or does it hold up? Or just what are your opinions?
