The folks at Smartwool are pretty clever. Rather than just blasting out a message about their product (which are often baselayers and don't have much visibility when you're out and about on the mountain), they decided to have some fun. For a chance to win free Smartwool gear, you can "Strip to your Smartwool" by taking a picture of you in just your Smartwool. Yes, this often means having some fun at the top of a mountain. Of course this is a plug for our sponsor...but we also think it's an awesome promotion that's better than your standard advertisement. Smart thinking, Smartwool-ers!
