Reviews: Massif Flamestretch Sock System
This product has not yet been reviewed.
Massif produces clothing that performs. Starting from the fiber level, it builds the best gear possible. Founded by veteran search and rescue team members and alpine climbers, its products combine the protective traits of fire rated (FR) gear and the functionality of outdoor clothing. However, this was not an easy task. It required the creation of a new generation of FR fabrics. In 1999, Massif started with just two employees; now the company is one of the leading suppliers of flame resistant, high performance outdoor apparel for the public safety community. Despite its rapid growth, Massif remains true to its commitment to outfit those with dangerous professions with quality, protective gear.
