Kids seldom want to stop for anything, be they naps, baths, or rehydration, which is why it's a good idea to send your progeny off to the mountain prepared with water on hand. The CamelBak Kids' Kicker Hydration Pack offers a 50 ounce bladder for your unstoppable little monsters. A PureFlow insulated drinking tube keeps the vital water supply flowing during the chillier days on the mountain. HydroGuard technology prevents bacterial growth on the inner surfaces, while the external storage pocket holds essentials like a granola bar or spare gloves. CamelBak has also fitted this polyesternylon pack with an attached safety whistle in case you and your child accidentally separate.
