      Technologies

      Mobile Warming® Heating Technology

      Powerful Warmth, Precisely Delivered

      Mobile Warming® Heating Technology uses ultra-thin, flexible heat pads powered by lightweight rechargeable batteries. Strategically placed throughout the garment, these pads deliver consistent, adjustable warmth at the touch of a button—so you stay comfortable in any condition, without the bulk.

      MW Connect™ Bluetooth® Wireless Control

      Bluetooth Control at Your Fingertips

      MW Connect® Bluetooth Control Technology lets you wirelessly manage your heat settings right from your smartphone or smartwatch. Adjust temperature levels, monitor battery life, and customize your comfort—anytime, anywhere.

      Zapsheer™

      Static-Free Comfort

      Zapsheer™ Technology integrates conductive fibers into the fabric to safely dissipate static electricity. It reduces static cling and minimizes the risk of sparks, making it ideal for both everyday wear and electrostatically-sensitive environments.

      Odorsheer™

      Stay Fresh, Longer.

      Odorsheer™ Technology fights odor at the source with advanced antimicrobial properties woven into the fabric. It keeps your gear smelling fresh, even after extended wear—so you can focus on the adventure, not the laundry.

      SWEATSHEER™ Moisture-Wicking Mesh Liner

      Moisture-Wicking Comfort That Keeps You Dry
      Sweatsheer™ Technology uses advanced polyester mesh to pull sweat away from the skin and speed up evaporation. Built for active performance, it keeps you dry, comfortable, and focused—no matter how hard you push.

      Features

      Includes Powersheer® Mini 2250mAh 7.4volt Li-Ion Battery

      Compact Power, Built for Comfort

      The Powersheer® Mini 2250mAh 7.4V Battery is our lightweight Li-Ion power source designed for maximum comfort and performance. With USB-C charging, an easy-to-read LED battery life indicator, and a compact size, it’s the perfect match for most 7.4V heated garments—delivering reliable warmth without added bulk.

      Battery Storage Pocket

      Power Where You Need It
      Our battery pocket is designed for seamless integration with your heated gear. These secure, low-profile pockets keep your battery packs in place for optimal comfort and performance—so you can move freely while staying warm all day long.

      Thermal Knit Outer Shell

      Midweight Performance Knit
      Shown here is the performance outer shell of our mid-weight baselayer, constructed from a thermal knit fabric that offers warmth without bulk. Engineered for active comfort, it delivers stretch, breathability, and insulation for cold-weather layering.

      Moisture Wicking Inside Liner and Side Panels

      Stay Dry, Stay Comfortable
      Our moisture-wicking liner pulls sweat away from your skin to keep you dry and comfortable in any condition. Whether you're on the move or layering up, it helps regulate temperature so you never feel soaked or chilled.
