These heat treated all Aluminum 7075 Ultralite poles are the Adventure Racers' poles of choice. No bells and whistles here, just a compact size with Foam Grips and comfy Straps. The 360° turn back security of the Super Lock System (SLS) was proven to be the strongest by TUV, an independent testing lab. The reduced weight is because there is no Antishock mechanism but this pair of poles sure can take you where you want to go. Carbide Flextips are added security on rock and ice.
