Part of this fun collection is Hydra, a clear straight tube ice bong with a coloured accent on the bowl, base, percolator, mouthpiece and custom monster logo is extremely easy to clean and maintain. The tree percolator makes the hit incredibly smooth. It features a removable slitted inside-cut 18.8 > 14.5mm downstem for added diffusion and easy removable cleaning and ice notches, for optimal filtration with a frosty touch. The Hydra straight tube comes delivered with a male 14.5mm herb bowl with handle. The handle not only makes it easy to lift the bowl, without the risk of burning your fingers, but it doubles as a roll stopper as well.
