The NEW and IMPROVED HeadCase brings portability to everything from smaller hand pipes to vaporizers. The RYOT Smell Safe Carbon Series locks in odours. Durable exterior weatherproof canvas fabric. Pack and Protect with RYOT. The SmellSafe Carbon Series incorporates extensive carbon fibre padding that both neutralizes and traps odours in its pores while our coated weather-proof fabric and moisture seal zipper provide a true physical barrier to keep odours in and the weather out. To re-activate the Carbon lining filters, simply put in the dryer for 5 minutes.
