CamelBak Ultra™ Belt 17oz

The CamelBak Ultra™ Belt 17oz is a minimalist waist-mounted running hydration belt built for short to mid-distance efforts, combining a collapsible 17 oz Quick Stow™ flask, breathable 3D Micro Mesh, and streamlined storage in an ultralight low-profile design.

Why It Stands Out

• Minimalist Running Design: CamelBak positions the Ultra™ Belt as its lightest and most minimal waist-mounted hydration solution for running.
• Collapsible Quick Stow™ Flask: The included 17 oz flask molds to the shape of your body while full and packs down smaller once empty.
• Breathable 3D Micro Mesh: Multi-directional airflow and cushioning help keep the belt light, comfortable, and breathable on warmer runs.
• Practical Storage: Stretch and zippered storage areas give you room for essentials like gels, keys, cards, and a phone.
• Technical-Run Utility: An integrated trekking pole carry helps the belt adapt to more technical running routes.

Ideal For

The Ultra™ Belt 17oz is a strong fit for runners who want a lightweight hydration option without stepping into a full vest or pack. It works especially well for shorter trail runs, road training, hot-weather workouts, and technical runs where carrying a handheld bottle feels less convenient.

How It Compares

Compared with a running vest, the Ultra™ Belt is lighter, simpler, and less bulky for shorter efforts. Compared with a handheld flask, it frees up your hands while still keeping hydration and essentials close and easy to access.

Bottom Line: The CamelBak Ultra™ Belt 17oz is a streamlined running hydration belt for athletes who want ultralight comfort, a collapsible flask, and just enough storage for key run essentials.

Add it to your running setup for a lighter, cleaner way to stay hydrated when a bigger pack is more than you need.
