Thule Vital 8L hydration backpack has a 2.5L Hydrapak reservoir and expandable cargo space designed to fit all the gear you need for a day out on the trails.

Constructed specifically to improve bike handling and reduce muscle strain, the hydration pack has a low center of gravity for optimal weight distribution. Another unique feature is the Thule ReTrakt hydration hose, the magnetic design allows the hose to automatically snap back in place in between sips. This means you can stay hydrated, but still save time and focus on the trail ahead. The hydration pack's lightweight, ventilated materials ensures a comfortable ride and the 8L cargo storage allows you to bring with a jacket, tools, food, and other items. It also makes a great companion on day hikes or other outdoor activities.
