The Spark S is a solid ski pole, proving once again that 'poles aren't just poles'. The Spark S is a pole that lists for under 100 bucks and still has the Leki Trigger system that makes skiing safer. You might have just asked yourself what makes skiing with poles dangerous. Well, the trigger system acts like a ski binding; if you mess up or fall hard the binding will release or eject you - Trigger poles do the same thing. The Spark S is a lightweight pole with a great grip.
