The SealTank is BBB's most water resistant top tube bag, designed for cycling in all weather conditions due to the welded seams and waterproof fabric. The special design makes sure it fits perfectly on top of your top tube, and the three velcro straps keep your SealTank right in place. The special water resistant zipper is easy to open and the special blue inner lining makes sure you can find your stuff easily inside without having to take everything out.
