Tacx Shiva water bottle 16oz (500ml): These bottles have been a favorite of Pro Teams for years. It’s easy to squeeze, easy to grab, easy to lock, and easy to clean. The Shiva bottle has an ergonomic design and features a lockable spout, extra grip, and a cap with a lockable pull spout that won’t spring open or leak. All with the magic of a custom Skratch design!
