ISPO Award Winner 2025: One-Piece Super Polar Workwear from Bosideng

At the heart of this high-tech one-piece suit is a sophisticated protection system that works reliably even in Arctic conditions. The combination of a Gore-Tex ePE membrane and improved seam sealing with ultra-light adhesive tape, applied using high-temperature bonding, guarantees complete windproofing and waterproofing without compromising breathability. In addition, the inner seams have been covered with cotton strips to prevent cold bridges. 

A special 3D down chamber structure effectively counteracts cold spots. These chambers are filled with water-repellent, antibacterial 800+ fill power goose down combined with a far-infrared heat storage material. This can locally increase body temperature by up to 2.7 °C. 

In areas of the body prone to perspiration, moisture-wicking fabrics are combined with IMBOTEX Antarctica padding insulation and additional ventilation openings. These accelerate the release of moisture beyond the insulation layer. The side zippers feature a ventilation design that significantly increases airflow when opened, thereby reducing condensation and ice formation. Together, all these elements form a breathable circulation system for the entire body. This system ensures that the body remains dry and comfortable during high-intensity outdoor work and frequent transitions between indoor and outdoor environments. 

The product design has been consistently tailored to the practical needs of scientists. An integrated carrying system distributes the load to the hips during strenuous activity, and internal straps enable the suit to be quickly put on or taken off when transitioning between outdoor use and vehicle rotation. A round zipper at the back makes it easier to use the toilet. Abrasion-resistant zones made of recycled 200D Cordura protect the suit in high-stress areas over the long term. 

The ergonomic design ensures unrestricted comfort even during dynamic movements such as climbing, lifting or kneeling — an essential requirement for working in hostile environments. 

In addition to its extreme functionality, the polar suit also impresses with its sustainability concept: all materials have been selected for their environmental compatibility and durability. The PFC-free ePE membrane from Gore-Tex, RDS-certified down filling, and the use of 100% recycled Cordura show that high-performance clothing can also be designed with the environment in mind. Production takes place under strict ESG criteria in Bosideng's own manufacturing facility, which has been awarded an MSCI ESG rating of “A.” The sustainable product concept is rounded off by a lifetime repair service. 

• Highly functional weather protection under the most extreme conditions
• High wearing comfort, even in changing temperatures
• Ergonomic properties and pressure-relieving design
• Use of more sustainable and certified materials 

“Designing for Antarctica’s inland regions, where temperatures can drop to –60°C, pushed us to rethink every aspect of warmth and protection. For our design team, this project was about finding the balance between absolute performance and practical usability in one of the harshest environments on Earth. Every seam, chamber, and material was tested to ensure comfort and safety for scientists working there. Receiving the ISPO Award is a great honor for us—it recognizes Bosideng’s continuous exploration and innovation in the field of functional down apparel.” Bosideng Design Team 

“With this amazingly lightweight suit, Bosideng has taken a close look at the harsh working conditions in hostile environments and combined the latest technologies in fabrics and construction with many useful, innovative details. As inconspicuous as the suit may appear on the outside, its workmanship on the inside is enormously complex.” ISPO Award Jury
