Primus Thermal Mug

Durable mugs for hot and cold drinks

A good mug makes the break easier, whether you are drinking morning coffee by the tent, tea during a day trip or something cold at the rest stop. Primus stainless steel mugs are made to withstand outdoor life, packing and daily use without absorbing or affecting taste.

Several of the mugs have a double-wall construction that helps the drink keep its temperature longer than in a regular single-wall cup. This makes them practical when you want to hold the mug comfortably, even when the contents are hot.

When the drink needs to keep its temperature for longer in a backpack or bag, vacuum flasks serve a different purpose than open mugs, as they are built to transport coffee, tea or other drinks over a longer period of time.

Practical design for outdoor life and everyday use

Primus mugs are designed to be easy to use often. Stainless steel provides durability, the large opening makes them easy to fill and clean, and several models have shapes that work well in your packing, by the campfire or while travelling.

For commuting, car trips and days when the drink needs to come along between different places, travel mugs are better suited than an open mug. They are made for coffee and tea on the move, while the mugs on this page are best suited when you sit down, take a break or want to drink directly by the stove, campsite or coffee stop.

Choose the right mug for your needs

Which mug suits you best depends on how it will be used. A double-wall mug is practical for hot drinks because it insulates better against the hand. A kåsa or drinking glass in stainless steel is better when low weight, durability and easy packing are more important than temperature retention.

On shorter trips, a compact mug is often enough for coffee, tea or hot chocolate. During longer days outdoors, the mug can be combined with a vacuum flask or cooking equipment, so the drink can be heated or refilled when needed.

Mug for outdoor life, travel and everyday use

A stainless steel mug is useful in many situations. It works for breakfast at the campsite, during the coffee break on a hike, in the boat, by the grill area or as a durable cup in everyday life. The main advantage is the combination of durability, easy cleaning and low risk of the material affecting the taste.

When the meal is more important than the drink, food flasks are better suited, as they have a wider opening and insulation adapted for soup, stew, pasta and other food that needs to keep its temperature until the lunch break.

The mugs on this page are best suited as open drinking vessels. They are easy to use together with a camping stove, vacuum flask or other outdoor equipment when you want to drink directly, pour a hot drink or serve something cold without disposable cups.

Frequently asked questions about thermal mugs and outdoor mugs

Here are answers to common questions about materials, use and cleaning of Primus mugs.

How long does a Primus mug keep drinks warm?

A double-wall mug keeps the drink warm longer than a single-wall cup, but it does not work like a closed vacuum flask. Temperature retention is affected by the amount of drink, the weather, the material and how long the mug is left open.

Are Primus mugs leakproof?

The mugs on this page are open drinking vessels and should not be packed with liquid in a backpack or bag. For transporting hot drinks, a vacuum flask or travel mug with a lid is a better choice.

Can I wash my mug in the dishwasher?

Hand washing is often best for preserving the finish and details for longer. Warm water, dish soap and a dish brush are usually enough to clean stainless steel after coffee, tea or meals.

What size mug should I choose?

A smaller mug works well for coffee and tea during shorter breaks, while a larger mug provides more volume for hot chocolate, soup or other drinks. For hiking and travel, packability, weight and handle design can be just as important as volume.
