The Slym Case with X-Strap technology makes carrying your essential portables and accessories a breeze. The RYOT Smell Safe Carbon Series locks in odours while the durable exterior is made of 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.
