Rail Hydration 4L Hip Pack

What Our Gearhead® Experts Are Saying:

"I wore the Rail Hydration 4L Hip Pack on a two-hour singletrack loop, and the magnetic hose snapped right back into place every time I let go, so I never had to look down mid-descent. The side pockets held my snacks exactly where I could reach them without breaking stride."

A ride only flows when you're not thinking about your next sip, and the Rail Hydration 4L Hip Pack from Thule is built to keep it that way. Picture a fast singletrack descent with both hands locked on the bars, the trail dropping away in front of you, and a hose that finds its way back to your hand the instant you need it.

That comes down to the ReTrakt magnetic hose, which snaps back into place between sips so your focus never leaves the trail ahead. A structured, breathable build keeps the pack stable over rough terrain rather than bouncing with every hit, while side jersey pockets and a front flap keep snacks and small tools organized and within easy reach.
