Kit Review: Arpenaz 26 Cooler

Kit Review: Arpenaz 26 Cooler

When the package containing the Arpenaz 26 cooler arrived I was more than a little sceptical. How could anything that small contain a picnic for a family let alone keep it cool for any appreciable length of time?

OK, I knew from the blurb sent out that it was expandable so capacity didn’t really matter. However, cool boxes or bags are bulky due to the insulating materials and the Arpenaz 26 gave the appearance of not having enough bulk to do the job properly.

Too small to be any good? I was soon to discover that size was misleading

Unpacking the Arpenaz 26

The first thing I noticed was the weight; or rather the lack of it. At less than 1kg it could be easily packed if you were flying off on a self-catering holiday. The quoted dimensions when closed or deflated are 30cm x 40cm x 12cm. There is an elasticated strap, fixed at one end so you don’t lose it, that keeps the cooler compact.

One of the innovations of the Arpenaz 26 is the self-inflating technology. The strap is removed before inflating and the air valves opened. There are two valves, one on the lid and one on the front of the cooler. I followed the instructions and left the cooler to inflate itself. It took almost four minutes to inflate, enough time to brew a coffee. However it was not quite fully inflated and, as suggested in the instructions, needed to be inflated manually. All it took was one long puff through the front valve. The valves are then closed and the cooler is ready for use.

The science behind the Arpenaz 26

Now for the technical bit; non-techies can skip this bit.

Apparently the material on the inside, the silver lining, is designed to keep the cold in. The material used on the outside deflects solar radiation and reduces the impact of heat. Between the two the Arpenaz 26 makes use of the wonderful insulating properties of air. Although the technologies used in the materials are advanced the principle of keeping cold in and heat out is simplicity itself and in various forms what most coolers use.

The materials used inside and out combine with the insulating properties of air to make the Arpenaz 26 the most efficient cooler on the market

Fully inflated the dimensions are 30cm x 40cm x 42cm which means the capacity of the Arpenaz is 26 litres.

The Arpenaz 26 in use

Living on the edge of the New Forest National Park means we quite often head out for a picnic. Having the Arpenaz 26 to review gave us the perfect excuse for a trip into the New Forest. Ice blocks and picnics were put in and the zip lid closed. Despite a picnic for two, several water bottles and the ice blocks it was far from full. There was ample space for picnic supplies for a couple of friends or children (ours have flown the nest). An adjustable shoulder strap is firmly fixed to the sides but I found the bulk a little awkward to carry and I would not want to carry it too far.

The Arpenaz cooler was left in the car, in the shade while we spent three hours out in the forest. When we returned the shade had vanished and the car was in full sun. It would be a real test for the cooler. Our experience with rigid cooler was that the interior would be only marginally cooler than the inside of the car so I was not, despite the marketing blurb, expecting much from the Arpenaz 26.

Left in a car in full sun the Arpenaz 26 still kept the picnic chilled

I have no idea what the temperature inside the car was but it was like a furnace. Taking the cooler out I was surprised at how cool the outer surface felt. Obviously it was doing what it was designed to do and deflecting solar radiation. Opening up the lid I felt the chilled air waft past my face. This all looked, or rather felt, rather promising.

The picnic inside was as chilled as when it had been put in. The drinks were wonderfully and refreshingly cool; the picnic itself was fresh; the salads were cool; and the butter for the rolls was still to solid to spread. I found it difficult to believe that anything could have been kept cool in the furnace of a car left in the sun.

A handy outside pocket for keys and a flask of coffee are a thoughtful addition

Without the use of thermometers it was not possible to give temperature lost over time data for my “in the field” test. However the independent test technical data of the Arpenaz 26 shows it takes 11 hours for the interior temperature to rise by 10°C in ambient temperature of 32°C.

The results of my test and the test under laboratory conditions are very impressive. This is certainly a product I will be taking to France and the Mediterranean when I head off on a camping/caravanning holiday.

Do I have any gripes? Yes, there are a couple of minor ones in addition to the awkward to carry gripe mentioned above. The pale colour of the exterior (which I realise is necessary) does mark very easily. I am also worried about the possibility of puncturing either by sharp objects on the outside or sharp implements such as knives and the cutlery stored inside. A puncture would render it less effective.

However despite these minor issues it is a top class product. It is well made and looks durable; I haven’t had it long enough to test the durability but I will come back to that in a few months. At £32.99 it is great value for money if you like the outdoors or just the occasional picnic.
