Altura: A FULLY WATERPROOF TOP TUBE BAG TO PROTECT THOSE RIDE ESSENTIALS ON ANY ADVENTURE Designed to adjust to different frame configurations and to be easily detachable, this fully waterproof Altura Vortex 2 Waterproof Cycling Top Tube bag is the ideal way to carry smaller essentials or fuel easily within reach on the frame when bike packing or commuting. It is not just the bag's fabrics that keep the water out as a waterproof zip provides protection against the elements, keeping essentials dry, all of which can be organised in a number of internal compartments.Whilst the waterproof fabric and welded seams provide protection from the elements, this product is not submersible and should not be left sitting in water. We recommend valuables or electronics should be secured in a dry bag inside the main body of the bag for extra security.
