How to Choose the Right Size?

 

 

Consider Your Daily Needs

• Consider Your Daily Needs
If you like fresh, hot coffee, a 12-20 ounce mug might be enough, like the Ozark Trail 18-ounce Thermos. It also has a handle, making it easier for people with smaller hands to hold. A 20-30 ounce mug might be better for drinks like water, iced tea, or cocktails. If you have a long commute, thermoses like the Stanley Quencher are great because they don't require frequent refills.

 

• Portability and Size Compatibility
If you want a tumbler that is easy to carry, you can choose a 20-30 ounce tumbler. For example, the RTIC 20 ounce tumbler and the YETI® Rambler tumbler with straw lid can fit into a car cup holder and are suitable for commuting.

Portability and Size Compatibility

 

Usage Scenarios

• Usage Scenarios
You can choose travel mugs of different capacities for different usage scenarios. For example, for daily commuting, you can choose the RTIC 20-ounce travel mug, which has enough capacity and is compact, making it very suitable for use in the car. For outdoor activities such as picnics and camping, you can choose the Ozark Trail 18-ounce travel mug, which is not too large and bulky.

 

• Heat Preservation
If you need to keep hot or cold drinks for a long time, look for a larger tumbler for better insulation. For example, the Stanley Quencher 40-ounce tumbler has a double-wall vacuum insulation design that keeps coffee hot or cold for a long time. The Corkcicle Cruiser 40-ounce tumbler also has excellent cold-keeping performance, especially for iced coffee lovers.

Heat Preservation

 

Cup Lid Type

• Cup Lid Type
The cup lid types of travel cups vary, and you can choose according to your drinking habits. Stanley Quencher 40 ounce tumbler's flowstate 3-position lid provides three options, namely straw mouth, drink mouth and full cover cup lid, to meet your different needs.

 

• Personal Preference
Personal comfort and preference are also important. The CamelBak Thrive™ Leak-Proof Cup is available in a variety of sizes, from a smaller 16 oz. to a larger 32 oz. It also comes in a variety of colors, so you can choose according to your preference.
