Compact Power, Built for Comfort

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.

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.

Built to Last, Zip After Zip
We use premium YKK® zippers for smooth operation and rugged durability you can count on. Whether you’re layering up in the cold or venting heat mid-hike, these trusted zippers won’t let you down.

Fleece Outer with Sherpa Lining
A soft sherpa lining delivers next-to-skin comfort and extra insulation, while the fleece outer shell adds rugged warmth and visual texture. Ideal for staying cozy on chilly mornings or layering up for all-day adventures.

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.

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.

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.

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.

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.
