Thule Rail 12L

hydration pack 12L covert green

Thule Rail 12L hydration pack has a 2.5L hydration reservoir for day-long rides and a secure fit to eliminate movement on aggressive trail rides or enduro races.

Push the limits with a Thule Rail hydration pack

The hydration backpack has optimal weight distribution thanks to its low center of gravity, which improves bike handling and reduces muscle strain. The superior stability and secure fit is also ideal for aggressive downhill riding, jumping and enduro races. The Thule ReTrakt hydration hose has a unique magnetic design which allows the hose to automatically snap back in place in between sips. This means you can spend more time focusing on maximizing your performance.
