UltrAspire Titan Hydration Vest
Here's what other sites are saying:
Whether you're on a thirty-mile quest via mountain bike or by foot, rely on the UltrAspire Titan Hydration Vest to keep you well-hydrated and fueled. A large main compartment holds your spare tubes, rain gear, bike pump, and other mountain biking essentials or running layers, while a separate compartment holds the 2L water reservoir and multiple chest pockets house your salt tabs or energy goo.
This pack was originally developed with the long distance mountain bike racer in mind, where the ability to reach plenty of goods without stopping to remove the pack was key. However, the folks at UltrApire found that their runners like it too! Whether you pack light, or pack for a journey through the night, the Titan suites your needs for summiting high places.
