Polarbjørn II - Jasons Convertible    

The founder of Polarbjorn, is a very experienced Arctic traveller. Having mushed his team of Siberian Huskies since the beginning of the sixties, he is a very experienced man in winterly conditions. He has been working as a designer for various Norwegian producers of sports-equipment, because of his many years travelling under strong conditions. Many expeditions and hundreds of nights in a stormraged tent have passed him. In the Norwegian mountains, at Spitsbergen, Greenland, Baffin Land, Bolsheskemelskaya Tundra, Vaigatch and Novaja Zemlja. Staring up in the tentceiling wondering: - How can this be made better? The first "Polarbjorn I" was erected in 1977 under the trademark "lill-Sport". Since then, many designs labelled "Polar" have been presented to the Norwegian market. Pulkas, rucksacks, garments and dog-equipment.

Own production

In 1997 we started our own production, selecting "Ventile" as the basic raw-material for the special designed tent-models under the name of "Polarbjorn II". "Ventile" is a very expensive fabric, and therefore we can not deceit with the handwork.
Today, a few carefully designed models are made in our small workshop in Brasøy in the Norwegian North. During precise handcraft, each tent is carefully sewn for strength and durability and to the costumers wish. Every single part is carefully cut out by hand. Each parts are sewn together to the final product without compromises. With an ever lasting view of potential improvements.

The pyramid

Anyone who have studied the classic Arctic litterature, must have noticed that the pyramid-tent was the most used model. Why? Looks old fashioned today, but was it then? And now?
Not at all. The pyramid has the following advances compared to "modern" structures in cave- and tunnel-like nylonshelters":
- To put up a pyramid tent in full storm is no problem, even for one person alone: Just spread the tent on the snow, (one-pole model) eventually weighted down by dog-sled, pulka or rucksacks in heavy wind. Put one ski (or our special-designed snowpegs) in the pegloops in each corner. Throw the luggage through the opening, enter the tent with the pole and erect it. Afterwards it can be stabilized with stayers all over. The bigger models have four poles and can be erected faster and more easily.
- All heat produced in the tent,- by cooking food or just beeing there and breath, causes an airflow ascending to the top. In our tents there are two airvents mounted there. Moist dissappear trough. In a tunnel-tent, one must establish an immense draught to have the same effect. And great loss of heat is the result.

Details and materials

All our tents are constructed with double walls: Outer tent in "Ventile", (different colors and weight) and inner tent in white thin cotton. When you wake up in the morning after a really cold night, you will experience that everything above nose-level is scattered with rhyme. (Because of your breath).
When you start the Primus or Colemanstove, this will evaporate through the wall or airvents, and leave no moisture in our pyramidtents. This is because of the carefully selected "Ventile" for the outer tent. This also goes for the tunnel-entrance, which has "Ventile" covering the opening. In a nylon-cave this rhyme will trickle down the walls and end up in an pond, excactly under your sleepingbag!
All parts of outer tent which are exposed to snow on ground: Lower part of the walls (under nose-level) and snowskirts, are made of different types of polyamid (nylon) according to weight and strenght demanded for each model.
All seams are reinforced with 12 mm polyesterweb. Along the walls, and along the bottom with pegloops and snowskirts. All pegloops are sewn double 10 cm up on the walls, with room for ordinary pegs, skies or snowpegs. All seams have a triangle, 15 cm long, in the seam for the stayers. One row in 80 cm level from bottom, one 160 cm from bottom.
The airvents are made with foam-lining, a bronze string to keep them open, and a secure closure with Velcro and outer draw-string closure. The 18 cm long vents can be open still under severe vindconditions, as they always will bend leeway to the vind.
All measures has been taken to make our tents a secure place to take any Arctic or Antarctic storm. But they are also constructed to live in for days.

Inner tent

When you enter one of our tents, you will find a comfortable place to live. Either it is on shorter trips with one of our light-weight models in your rucksack or pulka. Or on longer expeditions with our "Polarbjorn II HD" or "Polarbjorn II Antarctic". The interior is white. In dark Arctic winters, one candle will be enough to lighten your evening. The inner tent is fastened to the outer with small shock-cords. The bottom in nylon is sewn to the innertent and extend 20 cm up on the wall and fastened to the seam between Ventile and nylon in outer tent. Thus leaving the bottom space as a flexible basin, which is important when erecting the tent in soft snow when the bottom is trampeled deep down.
The upper 60 cm of the innertent are made of meshnet, which allowes damp air to pass out through the airvents while cooking. Underneath is a lace-up ceiling, which lovers the height in the tent during the night. Mesh-net pockets on all the walls for keeping order in the equipment, mesh-net pockets and strings under the ceiling for drying clothes. Two hatches in the floor, - one serving as well or primus-standing. The other can serve as toilet in bad weather.

Poles and pegs

All poles are made of coated 20 mm aluminium tubing with 2 mm wall thickness.
"Polarbjorn snowpeg std" are 35 x 7 cm in plain aluminium. Stringloop in top for ordinary use, and stringloop in the middle for use as snow-anchor. "Polarbjorn snowpeg Lux" are 35 x 7 cm with stringloop in top and middle. Alubolt-hook in top and epoxyvarnished in red.
