Thule Rail 8L

hydration pack 8L obsidian gray

Thule Rail 8L is a hydration pack with a secure fit to eliminate movement on aggressive trail rides and 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 magnetic design which allows the hose to automatically snap back in place in between sips. This means less time fiddling with the hydration pack and more time focusing on the challenging trail ahead of you.
