NORDISK
Sirius 4 EXP
Intended use:
The Nordisk SIRIUS 4 EXP is a four person expedition tent developed for continuous year round use in the most demanding environments on the planet. It is intended for long duration expeditions, winter travel, high wind alpine terrain and remote polar conditions where failure is not an option. The tent is designed to provide a stable, weather proof living space that allows teams not only to sleep, but to live, cook and manage equipment safely during prolonged exposure to severe weather.
Sirius 4 EXP is designed on three core priorities:
1. Raw strength for all-weather use year-round
2. Superior space for four people and excessive winter gear
3. Supreme ventilation options in all kinds of weather
Product USP:
SIRIUS 4 EXP distinguishes itself through a rare balance of extreme structural strength, true expedition grade interior space and a ventilation system that performs even under the harshest conditions. The non stretch SilPoly flysheet remains taut when wet, eliminating deformation and the need for constant readjustment. Combined with high strength DAC aluminium poles that can be doubled-up for additional wind resistance and Nordisk’s Power Guy Out System, where each guy-line-holding webbing wraps directly around the poles, the structure achieves a level of stability far beyond conventional tunnel tent designs. Unlike many expedition tents that sacrifice liveability for strength, SIRIUS 4 EXP offers generous interior volume for four people and their equipment, two large apsides and five separate entrances.
Fun facts:
The name SIRIUS refers to the brightest star in the night sky, historically used by Greenlandic hunters for navigation during the dark winter months.
End of use strategy:
The SIRIUS 4 EXP is designed with longevity and repairability in mind. At the end of its initial lifecycle or if damages occur, the tent can be serviced through the Nordisk Care & Repair programme at Nordisk’s German Manufactory. Professional inspection, repair and component replacement extend the usable life of the product, reinforcing Nordisk’s commitment to durability as a core sustainability principle. Furthermore, SIRIUS 4 EXP built with increased in-field repairability in mind – the users can mend and fix any occurring damage and continue to use the tent without limitation until professional maintenance is carried out.
