Innovative SwitchRelease technology in the wrist strap with a lockable release adds a measure of safety in the event a pole gets caught in bushes or trees. The poles all-aluminum construction adds year-round durability, and the foam grip adds comfort while a dual density grip-top with a sticky rubber makes quick buckle and binding manipulation easy. 261 grams per pole (145cm length). 16 mm (.6 in) aluminum upper with 14 mm (.5 in) lower.
