Do you want the warmest hands EVER?

Then you need the Super Beast Liner.

Made to upgrade your Mitts to endure even the absolute coldest of temperatures.

When you put these into your Mitt System they will take the temperature rating from -31°F to 5°F (-35°C to -15°C). 

Tested and approved on Everest.

Includes:

• Super Beast Liner: BAÏST hybrid performance blend of Thinsulate and Thermolite removable velcro liner. Our blend is the warmest and most breathable liner you have experienced.

This liner is not typically used on its own. It attaches to the exterior shell of the mitt using velcro and is your main insulator. Remove the regular liner before inserting this into your Mitt.
