D'Addario Eco-Comfort Guitar Straps are made with 90% recycled materials. Fashioned from Repreve® high-quality recycled fiber and completed with eco-leather ends, each strap is a big step toward sustainability. Eco-Comfort Straps are also colored using the E-Dye Waterless Color System, which adds beautiful coloration without water — another major stride in environmentally conscious production. Aligned with D'Addario's continuing commitment to the environment, we're now offering Eco-Comfort straps. These straps are made almost entirely from recycled materials and are dyed with a waterless coloration process — so they're comfortable for players and the environment.
