Gibbon Slackline

If your guy is a little bit of an adventurer who likes testing his athletic prowess, give him a Gibbon Slackline from Marbles: The Brain Store this Valentine's Day. Simply string it up between two trees and your man will be acting like a circus tightrope star in no time. Plus, balancing on the slackline will improve his coordination and core strength. Pick one up from www.marblesthebrainstore.com for $100.
