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.
Ā
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!
Ā
Aerogel is a super insulator originally designed for the NASA Space Program. It is utilized in insulating satellites in temperatures as low as -450ĀŗF!


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 āPolarthin-XP Insulationā 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.
