New In: 37.5® Thermoregulation and Moisture Managing Fabrics for Active Sports

Our fabric collection is reaching new heights – we’re proud to introduce a made-to-order line crafted with exclusive 37.5® thermoregulation technology and moisture-management properties. These fabrics help regulate body temperature and keep wearers dry and comfortable. Pine Crest Fabrics is a verified supplier of fabrics made with 37.5® Technology. This premium line is ideal for high-performance apparel such as cycling, golf, hiking, outerwear, loungewear, and activewear.

About 37.5® Technology

37.5® Technology is a sustainable innovation made from naturally occurring volcanic minerals. Activated by body heat and humidity, it helps maintain thermal comfort by cooling the wearer when it’s hot and keeping them warmer when it’s cold. Whether you’re pushing through a tough workout, running intervals on a warm day, or recovering post-run, apparel made with 37.5® helps you stay comfortable and perform at your best.

How It Works

Active particles in 37.5® Technology capture the infrared (IR) energy naturally emitted by the body and use it to accelerate evaporation. This supports thermoregulation and adapts to a body’s needs, keeping a wearer cooler in the heat and warmer in the cold.

Key Benefits for Wearers

  • Dynamic Thermoregulation: Helps maintain an optimal core temperature of 37.5°C and ideal relative humidity next to the skin.
  • Sweat Management: Removes moisture in its vapor stage to delay visible sweat and keep a wearer drier for a long time.
  • Improved Stamina: Scientifically proven to reduce the energy needed to manage core temperature, boosting athletic performance by up to 26%*.
  • Sustainability: Combines natural minerals with enhanced biodegradability and recycled yarn options for an eco-conscious choice.
  • Odor Control: Traps odors and releases them during laundering, helping garments stay fresher longer.
