The Zac Brown Band have partnered with outdoor specialty retailer Gander Mountain for the band's Southern Ground product line. The retailer's 116 stores nationwide will carry the line of cookbooks, spices and sauces. In addition, an exclusive Zac Brown Band hat with a hand-tooled leather patch has been assembled by Brown's Southern Hide leather shop. The cotton twill hat, priced at $20, features an embroidered Soles4Souls logo. All proceeds from sales of the hat will benefit the charitable organization which provides shoes to underprivileged people around the world. Meanwhile, a handcrafted GranDaddy knife created at the Southern Grind shop in Georgia (available only at Gander Mountain's website) features a blade made of recycled saw blades and a custom sheath.
