Our (FR) FLEXSAFE™ long-sleeve is a thermal regulating layer that provides additional comfort, warmth, and safety to your workwear wardrobe. It fits comfortably beneath a shirt, sweatshirt or jacket for colder weather, and wicks moisture away from the skin keeping you dry when working up a sweat. The 4-way stretch fabric allows for total freedom of movement when performing any task on the worksite. FLEXSAFE™ performs like your favorite gym shirt – while protecting you with the quality you’ve come to love from MWG.
