CamelBak Zephyr Pro Hydration Vest

You can use both. While the vest comes with two 17oz Quick Stow soft flasks, it also features an internal sleeve designed to accommodate a hydration reservoir if you prefer carrying your water on your back.

Unlike a backpack that sits on your shoulders, this vest is designed to hug your torso like a garment. The dual adjustable chest straps allow you to cinch the vest down to prevent bouncing, while the body-mapped mesh zones ensure it stays breathable against your skin.

Yes, the trekking pole quiver is fully removable. This gives you the flexibility to strip the vest down to its lightest configuration for shorter runs or keep the quiver attached when you need extra stability for technical terrain.

Yes, the vest includes dedicated storage pockets designed to keep essentials like your phone, gels, and keys secure and accessible while you're moving. The pockets are positioned to minimize movement so your gear stays put.

The vest is constructed with an engineered knit mesh that is specifically body-mapped to increase airflow in high-heat zones. This helps regulate your temperature and prevents sweat buildup better than standard nylon fabrics.

The Zephyr Pro offers 11 liters of total storage capacity. This is ample space for mandatory race gear, extra layers, nutrition, and your hydration supplies, making it suitable for long-distance endurance efforts.
