The TuffRider Sport Canvas Duffle Bag is traditionally equestrian. Waxed canvas offers excellent water-resistance and is a stiff, durable material. If you are an avid equestrian and love to travel, this is a luxurious must have. Variations in color are expected in this material. Waxed canvas softens naturally in warmer temperatures and stiffens in colder temperatures. The natural variability of the fabric is what gives its rustic appeal.
