Adjustable poles: The Armada AK ADJUSTABLE are made from the highest quality and most durable 7075 Aluminium with wide, powder coated 80mm baskets. Metal tips for sticking into icy surfaces. The new and improved handle is made from a mix of cork and rubber to fit perfectly in the palm of your hand. There's a special extended grip zone under the handle, which you'll appreciate especially on steep zig-zag traverses, where you don't want to adjust the length of the pole with every turn. Inverted aluminium tube construction for extra durability (the diameter of the retractable parts of the poles is 16 mm and 18 mm). There is an adjustable wide wrist strap with a logo.
