Mammut works hard each year to make its Dyneema Contact Sling lighter without taking away any of its strength. Like most slings, Mammut made it out of super strong and light Dyneema, but unlike most slings, Mammuts Contact stitching technique ensures optimum handling and strength throughout the sling, even in the seam area. This makes it ready to please you whether youre sending sandstone, climbing crack, cranking ice, or alpine climbing your way to the top.
