The new cologne is the third fragrance from Tim, and it is described as capturing "Tim's most appealing attributes: gallant yet sensual, clean-cut yet rugged." The woodsy fragrance includes hints of lavender and orange flower with vetiver, musk, sandalwood and saffron.

His previous colognes are 2008's 'McGraw by Tim McGraw' and 'Southern Blend,' which came out in 2009.

Tim will launch his new Emotional Traffic tour, featuring Luke Bryan and the Band Perry, in Corpus Christi, Texas, on April 8.
