Velocity™ IT 1.5L

Went on a long trail run when it hit 90°F and the water stayed cold the whole way, even with the bladder pressed against my back. The insulated hose is the detail that sold me—no more drinking warm water on the final stretch.

The IsoBound insulation really works—my water stayed cold for hours on a scorching trail run. Even the drinking tube felt cooler against my lips, which made a big difference. Perfect for hot-weather hikes.

Filled it with ice water before a long bike ride and it was still cold two hours in, which never happens with my old reservoir. The insulated tube is a small thing but it genuinely keeps the first sip from tasting like warm plastic.
