Fellow Carter Cold Tumbler 591 ml – Hazy Blue travel mug

Fellow Carter Cold Tumbler 591 ml Hazy Blue – large travel mug for iced coffee

Fellow Carter Cold Tumbler 591 ml in Hazy Blue is the spacious 20 oz version of Fellow’s tumbler for cold brew, iced coffee, and other cold drinks.

With a 591 ml capacity, you get extra room for both coffee and ice cubes, while the double-walled vacuum insulation helps keep your drink cold throughout the day.

On the inside, you will find Fellow’s True Taste Ceramic Coating, and the included screw-top lid is combined with a straw, making it easy to take a sip without having to open or tilt the entire mug.

The result is a well-thought-out travel mug for those who want to take a larger portion of cold coffee to work, in the car, or on the go.

If you want to brew your own coffee, you can find the right equipment among our cold brew coffee makers.

591 ml – extra space for iced coffee and cold brew

The large Carter Cold has a capacity of 20 oz / approx. 591 ml.

This makes the model particularly interesting if you often make iced coffee with ice cubes or prefer a larger portion of cold brew to last throughout the day.

The extra capacity provides room for, for example:

• Cold brew with ice
• Iced coffee
• Cold filter coffee
• A larger portion of coffee for the workday
• Cold coffee for longer drives

Even though the capacity is larger than the 473 ml model, Fellow has maintained a body diameter of only 77 mm. Therefore, Fellow states that the Carter Cold fits in most car cup holders.

Vacuum-insulated travel mug keeps coffee cold

The Fellow Carter Cold is made of 18/8 stainless steel with double-walled vacuum insulation.

The vacuum between the walls reduces heat transfer between the drink and its surroundings, helping your cold brew or iced coffee maintain its temperature for many hours.

Fellow claims approximately 18 hours of cold insulation for the Carter Cold.

This is convenient if you fill the tumbler in the morning and want to return to a cold drink later in the day.

True Taste Ceramic Coating helps preserve the coffee's flavor

A travel mug shouldn't just maintain temperature – it should also provide the right conditions for the coffee to taste the way it’s supposed to.

That is why Fellow has equipped the Carter Cold with True Taste Ceramic Coating on the inside.

The ceramic coating is designed to minimize residual flavors, coffee oils, and metallic taste notes.

This is particularly relevant for coffee, where aroma, sweetness, acidity, and other nuances are an important part of the experience.

Fill the tumbler with coffee brewed from your preferred freshly roasted coffee beans, and take your cold coffee with you through the day.

Travel mug with straw and splash-resistant lid

The Carter Cold comes with a screw-top lid and Tritan straw, developed for easy sips throughout the day.

The straw has a diameter of 8 mm, and you don’t need to remove the lid or tilt the large tumbler when you want a drink.

This is especially practical:

• at the desk
• during the drive
• at work
• when you are on the go

Fellow describes the lid as splash-resistant.

However, this does not mean that the Carter Cold should be considered a completely leak-proof water bottle. Therefore, if the tumbler is to be transported in a bag, it is best to keep it upright.

Hazy Blue – understated blue Fellow design

Hazy Blue gives the Carter Cold an understated blue look that fits well with Fellow's simple and minimalist design.

The matte surface and sleek cylindrical shape make the tumbler an alternative to more traditional travel mugs if both function and appearance matter for your choice.

The larger 591 ml version is taller than the 473 ml model, but Fellow has maintained the same 77 mm diameter.

This gives you more capacity without making the tumbler unnecessarily wide.

Fellow Carter Cold 591 ml or 473 ml?

Both sizes have the core Carter Cold features, but the size makes a real difference in everyday life.

Choose 591 ml, if you:

• prefer a large iced coffee or cold brew
• want extra room for ice cubes
• want more coffee to last through the day
• don't mind a taller travel mug

Choose 473 ml, if you:

• want a more compact format
• normally drink smaller portions
• don't need the extra capacity

Both models have a diameter of 77 mm. The difference in capacity is therefore achieved primarily by the 591 ml version being taller.

Can the Fellow Carter Cold 591 ml be used for hot coffee?

Not with the included Cold lid.

Fellow specifically states that the Cold lid must not be used with hot drinks.

The Carter Cold with the included lid is therefore intended for cold drinks like cold brew and iced coffee.

How long does the Fellow Carter Cold keep the drink cold?

Fellow claims approximately 18 hours of cold insulation for the Carter Cold.

The double-walled vacuum insulation helps maintain the low temperature for many hours.

Is the Fellow Carter Cold 591 ml dishwasher safe?

Yes.

Fellow lists the Carter Cold as dishwasher safe. The body can be cleaned in the top rack, and hand washing can be chosen to treat the product even more gently.

Can the Fellow Carter Cold be put in the microwave?

No.

No parts of the Fellow Carter Cold may be placed in the microwave.

Is the Fellow Carter Cold 591 ml leak-proof?

Fellow describes the lid as splash-resistant, not completely leak-proof.

The Carter Cold is therefore suitable for, for example, the desk and the car's cup holder, but should be transported upright rather than left loose on its side in a bag.

Does the Fellow Carter Cold 591 ml fit in a car cup holder?

Fellow states that the Carter Cold fits in most car cup holders.

The 591 ml version has the same slim body diameter of 77 mm as the smaller model.

Can I brew coffee directly into the Fellow Carter Cold?

Fellow states that the Carter Cold fits under standard pour-over brewers.

However, it is not compatible with the AeroPress Coffee Maker or Prismo AeroPress Attachment.
