Trail Running
Trail Type
Rugged
The focus with the Matryx® Pack is evolution over reinvention. With our elite athletes competing at the highest levels in both the MTL Longsky 2 and the MTL Skyfire 2, the goal was to further tune these patterns to meet their needs.
The upper features a single-layer, Kevlar reinforced Matryx® woven textile that maximizes breathability and durability while dramatically reducing stretch. Internally the lining treatment wicks moisture while the midsole features our best FloatPro™ Foam for long distance comfort. Underneath, we use Vibram® MegaGrip® outsole with 5mm lugs offer maximum traction.
