All bottles and their matching caps age - even the TWIST bottles are not immortal. If the old bottle is still fine, but the cap is worn down, chewed up, or has developed a leaking issue, simply replace it with a Fidlock Twist Replacement Bottle Cap to suit TWIST bottles 800ml, 590ml, and 450ml.
. Only suitable for the 800ml, 590ml and 450ml TWIST bottles
. Not suitable for other TWIST bottles with "Made in Taiwan" printed on them
