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.

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.

Brushed Fleece Outer Shell
The ultra-soft brushed fleece exterior delivers warmth without the weight, making it perfect for layering or wearing solo on brisk days. Comfortable, breathable, and built for everyday wear from trail to town.

Essentials, Safely Stashed Inside
An internal storage pocket gives you a secure spot for your phone, wallet, or trail map—keeping the things you need close and protected. Whether you’re on the move or posted up at camp, it’s storage that stays out of the way but never out of reach.

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.

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.

Repels the Elements

Waterpell® Technology features a durable water-repellent (DWR) finish that sheds light rain and snow, keeping you dry and comfortable. Built to withstand the elements, it adds an extra layer of protection without sacrificing breathability.
