Why We Chose The Primus Klunken Thermos: Cool colour options, old-school cork top, wide mouth
It’s a streamlined and sleek bottle, designed for grip and functionality with a double-walled food-grade stainless steel making it insulating, incredibly robust, safe-to-use, and well-suited to an outdoor lifestyle.
The flask comes in 0.5 and 0.7 litre options, has a diameter of 6.5 cm, and a consistent height of 21.5cm. This makes it big enough to be useful for a few miles on the trail, whilst also suitable for day-to-day life.
It’s vacuum-insulated with a double-wall design that’ll keep your drinks hot or cold. The opening is also fairly wide so can accommodate easy cleaning, swift re-filling, as well as sizable ice cubes.
The slick colour options are perhaps what draw your eyes most immediately to this flask. They range from a classic stainless-steel colour to a powder-coated frost, black, ox red, yellow, green, mint, and pink. This powder-coating additionally make it easier to grip the bottle, even with wet hands.
The Primus Klunken is made from a 18/8 stainless steel that doesn’t retain or transfer flavours, regardless of the beverage.
“A streamlined and sleek bottle, with grippy technologies and a high functionality.”
The screw top is made with a cork centre, a Kånken webbing, and a steel rim, creating a cool, old-school aesthetic whilst retaining modern toughness.
