The OMSutra Chakra Rivet is a versatile yoga bag with a distressed grommet and rivets. The small grommets underneath give more room for air to circulate through the bag, keeping the contents drier and odor-free, so this piece is highly recommended for the hot or power yoga practitioner. It comes with an inside zippered pocket to keep keys and other items, and is roomy enough for mats, towels, water bottles or a change of clothes. Each bag is made of strong, durable cotton twill fabric and fully lined with soft cotton. It comes with pull chord closure, designed to hold any heavy mat comfortably.
