Velocity™ IT 2L

The insulation on this reservoir really works—my water stayed cold even after three hours in direct sun on a hot trail run. The bite valve is smooth and easy to use with one hand.

Took this on a 6-hour hike in July and the water was still cold at the end, which honestly surprised me. The IsoBound insulation really does something, and the insulated top kept the mouthpiece from getting that warm plastic taste.

Filled it with ice water before a 90-degree hike and it was still cold two hours in, which my old uninsulated one never managed. The insulated cap is a small thing but it stops the dribbling down my back.
