Technologies and Features

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.

Rainguard® Integrated Waterproof Liner

Waterproof and Breathable

Rainguard® Technology features a field-tested polyurethane shell with fully sealed seams to block out rain, sleet, and snow. Engineered for extreme conditions, it delivers complete waterproof protection without sacrificing breathability, mobility, or comfort—no matter the climate.

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.
