Thule Rail Hip Pack 4L with 1.5L Hydration
Built for riders who demand performance on technical terrain, the Thule Rail Hip Pack 4L delivers smart hydration, secure storage, and all-day comfort in a compact, low-profile design. Whether you’re climbing, descending, or navigating tight singletrack, this lumbar pack keeps everything stable, accessible, and dialed in.
The highlight is Thule’s patent-pending ReTrakt magnetic hose system, allowing quick, hands-free hydration without breaking your rhythm. Paired with a 1.5L hydration reservoir, you’ll stay fueled and focused on longer rides. A dedicated, soft-lined phone pocket offers one-handed, behind-the-back access—perfect for quick checks without stopping.
Designed for aggressive riding, this pack offers superior stability and a snug fit, reducing bounce even on rough descents. Breathable materials enhance airflow to keep you cool, while the ergonomic design ensures lasting comfort.
Inside, you’ll find well-organized storage with dedicated compartments for tools, accessories, and essentials. There’s room for extra layers, snacks, and ride gear, plus side jersey-style pockets for fast access to nutrition. A front flap pocket keeps smaller items secure and easy to grab, and a rear light attachment loop boosts visibility when riding in low-light conditions.
