      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

With built-in Bluetooth connectivity for use with our MW Connect® App, plus a Micro USB charging port and LED battery life indicator, these compact batteries deliver smart, streamlined warmth right where you need it.

      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.

      Wrist Gaiters

      Seamless Warmth, All Day Long
      Built-in wrist gaiters create a snug seal around your hands, preventing cold air from sneaking in. Perfect for active days and changing weather, they keep the warmth in without adding bulk.

      Zippered Side pocket
