Vector: Latin for carrier. Vector: a location in Final Fantasy VI. Vector (Euclidean): a geometric entity endowed with magnitude and direction. We like Latin; its a bag, something you carry stuff in, any stuff, anywhere simple. A versatile, all-round city / trail day pack for everyday use. The Vector is one of Lowe Alpine's best-selling day packs at a great price and with enough features to be your perfect companion, whether it be day trips to work/school, shopping or chilling in the park.
