Thermore introduces a unique insulation product that features a “boost” in cold weather performance when needed. Thermore’s Thermal Booster smart insulation is engineered to offer a consistent warmth level under normal conditions. However, as temperatures start falling, the product offers a thermal “boost” in performance to maintain comfort. Independent test labs prove that Thermore^® Thermal Booster is 20% warmer at lower temperatures. Additionally, the insulation features Thermore’s proprietary fiber migration treatment and can be machine washed without adversely affecting performance. Thermore^® Thermal Booster - extra warmth that always stays with you.
