Cotton does not perform. It persists. Wound from a cotton-wrapped polyester core, Spores carry the strength of synthetic construction beneath the feel of natural fiber. The polyester holds tension and resists wear long past the point where other strings have begun their slow decline. The cotton wrap keeps the hand soft, warm, and present. It does not disappear into the play. It reminds you it is there. Named for the mechanism by which certain organisms ensure continuation, not through urgency, not through speed, but through quiet, patient dispersal, Spores are not the fastest string in the catalog, but they are the one that will still be on your fixie when you finally decide to change throws.
