The Latitude Carbon SS Climbing Sticks are designed to allow for flush stacking, making them more packable for saddle hunters and tree stand hunters. They are true 18 in sticks, in contrast to some other premium, ultralight options. At only 1 lb per stick, they are the lightest climbing sticks made in the USA. Made in the USA is an important point here. When using advanced materials to achieve premium specs, quality control is absolutely crucial. Quality control is difficult with overseas manufacturing. Carbon SS Climbing Sticks are TMA tested and approved. 5-year warranty included.
