Nathan Sports VaporAiress 3.0 Hydration Pack

The VaporAiress 3.0 uses a women-specific design with adjustable side straps that allow you to cinch the vest for a snug, personalized fit. This helps prevent the pack from bouncing or shifting while you run, regardless of your specific frame.

Yes, the vest is constructed with a 2-layer moisture-wicking air mesh that promotes airflow. Additionally, the contoured chimney back panel is specifically designed to vent heat away from your body, keeping you comfortable during intense efforts.

Yes, the vest is compatible with bottles and flasks up to 22 oz. You can use the front pockets to carry additional hydration if you need more than the 2-liter capacity provided by the main reservoir.

The pack offers 7 liters of total capacity, which is plenty for essentials. It features secure front shoulder zippered pockets for easy access to your phone or gels, plus an extended kangaroo pouch on the back for larger items like a light jacket.

Without the hydration bladder, the vest weighs 8.8 ounces. With the full 2-liter bladder included, the total weight comes to 13 ounces.

The vest includes reflective hits strategically placed to provide 360-degree visibility. This makes you much easier to spot by motorists or other runners when you are training in low-light conditions.
