I bought this shirt because I'm about to trek the Amazon jungle..no, not search Amazon.com but rather hike around the Amazon jungle in Peru.  What stands out about this shirt is all the utility pockets and the loose fit.  I'm a big guy..I call it muscles, others call it fat but heck, everyone's got their own opinion/perspective on things.  Shirt fits great and I have the comfort of knowing it's going to be durable. It's Columbia and although it's not the most stylish, it's going to be functional and not fall apart on me.
