Satisfy's modular thermal vest uses a novel removable PRIMALOFT® padding system which allows you to adjust the level of heat-retention depending on the temperature. If you're feeling especially tricky, you can pull the segments out on-the-fly and store them in the back pocket.

Signature SilverShell™ fabric shell is a highly-visible, durable outer layer which keeps the internal thermal layers protected from the elements and errant hazards on the trail.

SilverShell™ – Made in Switzerland by Schoeller—known for their on-going collaboration with the NASA. SilverShell™ is a structured fabric interwoven with metal threads, which makes the fabric reflective as well as resistant to tearing and ripping.
