It’s available in multiple colors like Pink Bow for a personalized touch.

How long will my drink stay hot or cold in this tumbler?

The Trek tumbler uses double-wall vacuum insulation to slow heat transfer, so beverages maintain temperature longer than single-wall bottles. While exact times vary by liquid and conditions, you can expect several hours of thermal protection for both hot and cold drinks.

• Double-wall, vacuum-insulated stainless steel construction
• 18/8 stainless steel resists corrosion and flavor transfer
• Large 40 oz capacity reduces the need for refills
• Lid design helps reduce heat loss and limits spills

Is the tumbler easy to carry and fit in cupholders?

The Trek is tapered to fit most car cupholders and features an ergonomic handle for comfortable carrying. The handle’s shape is integrated to avoid snagging while still providing a secure grip when you’re on the move.

• Tapered base fits standard cupholders
• Ergonomic handle designed for comfort and stability
• Large 40 oz size balances capacity with portability
• Lightweight for its size due to stainless-steel construction

What does the straw lid do, and is it spill-resistant?

The included straw lid is designed with four-way threading so you can orient the straw for left- or right-handed use or other preferences. It is leak resistant to reduce accidental spills during transport, and two reusable straws are provided so you can swap or replace as needed.

• Four-way threaded lid allows multiple straw positions
• Leak-resistant design helps prevent spills when upright
• Comes with two reusable straws for convenience and backup
• Easy to remove for cleaning and refilling

How durable is the tumbler and what warranty does it include?

• Premium 18/8 stainless steel construction
