Stay Hydrated While Keeping Your Eyes On The Trail

The Thule Rail 4L Hip Pack is the ultimate hip pack for all-day adventures. This source of ultimate hydration features four liters of storage space, an upgraded stability belt, integrated tool storage, and a 1.5-liter hydration bladder. The Rail 4L is a step-up from its smaller sibling, the Rail 2L, with an added hydration bladder instead of water bottle pouches and an additional storage pocket.

The Thule Rail 4L has a total of five pockets, including two stuff pockets on the hips, two zippered pockets on the main part of the pack, and a hidden pouch on the rear of the main compartment. Inside the main compartment of the Rail 4L there are three individual pouches for tools, elastic loops for CO2 cartridges or air pumps, and a key hook.

The belt part of this high-quality pack is made with a breathable nylon mesh fabric for airflow and has silicon grip stripes on the inside of the belt for a slip-free fit. The hook-and-loop waist belt combined with the adjustable buckle makes for a secure fit. To top it off, Thule threw in the ReTrakt magnetic hose retention system so your hydration hose stays put when you are not using it.


  • Locate and replace hydration hose without taking your eyes off the trail using the patented ReTrakt magnetic hose retention
  • Includes 1.5L hydration reservoir
  • One-handed, behind the back access to phone in soft, structured pocket
  • Ride in comfort and descend with confidence with superior stability and breathable materials
  • Organize tools and clothing accessories in interior pockets
  • Quickly access nutrition with side jersey pockets
  • Store additional small items in the front flap
  • Stay visible with a blinky light attachment loop
