Martin's next generation Lifespan 2.0 strings are engineered using a new, patented technology only available from Martin. This technology was developed to protect the core wire and the wrap wire to prevent corrosion without compromising tone. Authentic Acoustic Lifespan 2.0 strings look better, sound better and feel better, providing a smooth playing experience that reduces finger drag. Martin Authentic Acoustic Lifespan 2.0 strings offer next generation treatment for long life, great playability and feel and superior reliability with authentic tone.  Also available in 80/20 Bronze.

Martin's newly redesigned string packaging makes the product easier to identify and ensures a longer shelf life. Martin string packages now feature a unique color for each product family making it simple to efficiently browse their entire line and find exactly what you're looking for. Martin has also begun packaging their strings in a sealed flow wrap packet to help ensure that the strings stay fresher longer, allowing players to store strings for long periods of time without worries of tone degradation.
