This Jason Markk Repel Refill is an earth-conscious way to refill your repel. Not only does Repel deliver a "better-than-aerosol' spray, the refill helps reduce our environmental footprint.   The water-based propellent free formula creates a durable, but breathable barrier. It safely shields suede, nubuck, nylon, canvas, cotton, knits, and all other absorbent materials against liquids and stains. The odorless and colorless formula will not alter the look or feel of the material. Engineered with multi-patented technology, a fine mist combined with continuous spray functionality covers large areas quickly and evenly in all directions
