Nathan Sports TrailMix Plus 3.0

The TrailMix Plus 3.0 uses a multi-directional stretch material designed to contour to your body, which significantly minimizes movement. When adjusted properly, it stays secure against your waist to prevent the bouncing common with less structured belts.

The front pocket is designed to be expandable and is sized to accommodate most modern smartphones. However, if you have an exceptionally large phone with a bulky protective case, it may be a tight fit.

Yes, the updated holster design is specifically engineered for one-handed access. You can pull the flasks out and slide them back in without needing to stop or use both hands.

The belt includes two 10oz (300mL) flasks, giving you a total capacity of 0.5 liters of hydration. It is best suited for shorter to mid-distance runs where you don't need a full hydration vest.

The included flasks are designed to be secure, but like most soft-flask systems, they require the cap to be tightened properly to prevent drips. Ensure the seal is clean and fully engaged before heading out.

The shock cords provide extra external storage capacity. They are perfect for stashing a light rain shell, a hat, or gloves when you don't want to pack them inside the zippered pocket.
