Cotton Bacon Prime:- PRIME is our newest cotton wicking material and was developed specifically with RTAs, RDTAs, and squonking . PRIME uses a different strain of cotton that has naturally thicker fibers. These thicker fibers allow the cotton to absorb liquid at least 33% faster. It?s tasteless, free of impurities, natural oils, and pesticides. Use it anywhere you?d use V2, and especially in a tank or squonk situation!
