Perfect for any athletic adventure, CamelBak’s spillproof Performance bottle is produced from easier-to-squeeze TruTaste polypropylene – all you taste is your drink, not your bottle. Including an internal straw, transparent fuel guage and a lockable self sealing bite valve, the Performance bottle is ideal for runners as it does not need to be tipped up in use, allowing you to keep your eyes on the way ahead. Performance bottles are also top rack dishwasher safe.
