CamelBak Ultra Running Hydration Belt, Corsair Teal 2.0, Size Small-Medium, 17oz Quick Stow flask

The CamelBak Ultra Running Hydration Belt is a minimalist waist pack that carries a collapsible 17oz Quick Stow flask plus essentials with low bounce and breathable comfort for running.

If you want a compact, stability-focused hydration solution for tempo runs, trail miles or race day without extra bulk, this belt is engineered to sit close to your body and move with you. It combines a soft, collapsible flask that reduces sloshing as you drink, breathable 3D Micro Mesh for comfort, and a tidy zippered pocket for phone and small items. Reflective accents and an integrated trekking-pole carry make it adaptable for early-morning road runs and light trail use alike.

How does the collapsible Quick Stow flask reduce bounce and distraction?

The included 17oz Quick Stow flask is designed to collapse down as you drink so the fluid shifts less and the bottle stays snug against your hip. Its one-piece silicone bite valve gives a steady sip without fiddly parts, helping you hydrate without changing stride. Because the flask compresses, it keeps volume low and prevents the shifting weight that causes mid-run distractions.

• 17oz capacity that compresses as liquid is consumed
• One-piece silicone bite valve for smooth sipping on the move
• Low-profile shape to minimize bounce during high cadence

Will the belt stay comfortable on longer runs and in warmer conditions?

The Ultra uses 3D Micro Mesh to promote airflow and cushioning where the pack contacts your body, reducing sweat buildup and chafe over distance. The pack’s minimal volume and ergonomic cut keep it from digging in while remaining stable at faster paces. Materials are chosen to balance lightness and durability so comfort remains consistent mile after mile.

• Breathable 3D Micro Mesh helps manage heat and moisture
• Ergonomic low-profile design prevents pinching or rubbing
• Lightweight construction reduces fatigue on long efforts

What can I carry besides the flask, and is my phone secure?

A zippered pocket provides a protected space for a phone, keys, or nutrition, and sits flush so items don’t shift or jostle while you run. The compartment is sized for most modern phones and includes internal organization to separate small items. External attachment points allow you to stow a trekking pole or clip on an extra accessory when needed.

• Zippered pocket sized for phones and small essentials
• Internal organization prevents loose items from moving
• Trekking-pole carry and external attachment options for versatility

Is this belt visible in low-light conditions and suitable for mixed-terrain runs?

Reflective detailing increases visibility in dawn or dusk conditions without adding weight, and the pack’s secure fit keeps it stable on rolling singletrack or hard-packed trails. The trekking-pole carry lets you switch to poles quickly when terrain gets technical, and the minimalist profile avoids snagging on branches or gear. It’s built to be a versatile companion for runs that transition between road and trail.

• Reflective elements for added visibility in low light
• Stable, low-bounce fit for varied running surfaces
• Integrated trekking-pole carry for quick adaptability
