What is Polarthin-XP?
Polarthin-XP is a cutting edge aerogel fabric with up to 4 times the thermal insulation performance vs. traditional synthetic insulation materials.
Polarthin has been specifically engineered for use in performance clothing and cryogenic applications. This feat of scientific innovation does not require loft to insulate & maintains thermal insulation even when compressed to thinner than 1mm thick!
Aerogel is a super insulator originally designed for the NASA Space Program. It is utilized in insulating satellites in temperatures as low as -450ºF!


This graphic presents Polarthin-XP insulation technology for boots. The background image shows a person wearing dark brown lace-up boots while standing in a snowy outdoor setting.
The upper blue panel is titled “Polarthin-XP Insulation” and lists the following features:
- Best in class thermal insulation.
- Fully rebuildable.
- Ultra thin profile does not affect fit.
- Durable.
- Micro pores for enhanced breathability.
- Compression Resistant.
- Waterproof material.
A callout in the center states “Insulated vamp and midsole to keep you warm where you need it.” An illustration highlights the insulated portion of the foreground boot with a red overlay and heat-wave symbols.
Large text along the bottom states “4x the thermal insulation vs. traditional synthetic insulation materials.”
