Hydro Flask

40oz Travel Tumbler + Clear Lid

What Our Gearhead® Experts Are Saying:

“This is my go-to when I know I’ll be out all day—the capacity means fewer refills, and the lid handles bumps and movement without spilling.”

For long workdays, road trips, or hot afternoons when hydration really matters, the 40oz Travel Tumbler goes the distance. We rely on it when smaller bottles won’t cut it—keeping cold drinks within reach without constant refilling. Despite the larger capacity, the ergonomic handle and tapered base make it surprisingly manageable.

Built by Hydro Flask, the Travel Tumbler uses durable stainless steel and TempShield double-wall vacuum insulation to keep drinks cold for hours on end. The clear Press-In Straw Lid offers leak-resistant, splash-resistant performance while making it easy to see when it’s time to refill. A flexible straw supports comfortable sipping, turning this high-capacity tumbler into an easy everyday hydration solution.
