Warmth by Design. Made for Real Life.
Across more than ten years, Mobile Warming® has developed advanced heated clothing that keeps people comfortable in cold, demanding conditions. Our technology weaves thin, flexible heating elements straight into every garment, delivering steady warmth without restricting your motion or adding needless bulk.
Each piece features carefully positioned heating zones, chosen by how the garment is worn and where heat is needed most. Whether jackets and vests or gloves, socks and baselayers, the heating system is customized to the product and its intended use.
Thanks to several adjustable heat levels, you can adapt fast as temperatures, exertion and weather shift. Turn it up when it gets colder, turn it down as you work harder, or shut it off when heat is unnecessary. Mobile Warming places personalized comfort in your hands.
Behind each Mobile Warming® heating system sits a battery picked to match the product it powers. Powersheer™ lithium-ion rechargeable packs vary in voltage, capacity and shape, so heat output, runtime and wearing comfort stay in balance.
Small packs run products worn right against the body, such as socks and accessories, whereas larger-capacity packs drive bigger heating setups in jackets, vests, baselayers and other outerwear. Some models also bring Bluetooth® connectivity and USB-C charging, plus power-bank output, fast charging and built-in LED lighting.
Whether you want light everyday warmth or longer endurance in harsh conditions, Powersheer batteries deliver mobile power fitted to how each product is meant to be worn.

Warmth by itself is not enough to stay comfortable outside. Mobile Warming® garments pair active heating technology with weatherproofing fabrics selected for the conditions each product is meant for.
Protection ranges from water-resistant outer finishes that turn away light rain and snow, through to waterproof membranes, protective liners, and seams sealed with tape, and every level has its own job. Together they keep moisture from getting to the layers underneath while leaving the comfort and freedom of movement needed for work, play, and daily life.
Because every environment differs, the amount of weather protection in each garment is matched to what it is designed for. You get light, flexible versatility in mild weather and fuller protection when conditions turn harsh.
Fabrics and outer finishes that resist water make moisture form beads and run off the garment. This light tier of protection suits daily wear, drizzle, brief snow, and shifting outdoor weather.
Certain Mobile Warming products use built-in waterproof liners or breathable membranes that create a shield between the outer fabric and the person wearing it. These inner layers keep external moisture out while allowing heat and sweat to escape.
Our top-tier outerwear combines waterproof fabrics or membranes with taped seams. The tape covers the tiny gaps left where garment panels are sewn together, which stops water from getting through these weak spots.
Mobile Warming® technology generates heat on its own, and well-chosen insulation holds that warmth against the body. Together they make a more efficient system that keeps you comfortable in the cold without leaning on bulky, confining layers.
Each environment needs its own kind and amount of insulation, so our outerwear line pairs PrimaLoft® synthetic insulation with responsibly sourced duck down, selected for the job. Every material is picked to strike a balance among warmth, weight, freedom of movement, weather resistance and what the garment will be used for.
Whether it is slim insulation for active movement or high-loft down for maximum warmth, every layer teams up with our built-in heating system to get the most from each degree. The result is light, flexible comfort in mild conditions and fuller protection when the weather gets harsh.
Certain Mobile Warming® outerwear is filled with duck down certified to the Responsible Down Standard, giving outstanding warmth for very little weight. Countless soft down clusters create pockets of trapped air that keep in your own body heat plus the heat from the garment's built-in heating elements.
Under the Responsible Down Standard, supply chains become more transparent and animal-welfare rules apply, such as prohibiting live-plucking and force-feeding.
Light, lofty and easy to compress, duck down suits garments designed to deliver strong warmth in cold surroundings.
PrimaLoft® ThermoPlume® blends the lofty appearance, softness and packability of natural down with the reliable performance of modern synthetic insulation.
Tiny silky fiber plumes gather into clusters that fill quilted channels in a way similar to down, creating light warmth and a soft, raised feel. Compared with untreated natural down, ThermoPlume is built to perform more dependably when conditions turn damp or shift.
PrimaLoft® Gold Insulation offers high-performance warmth with a lightweight, slim build. Very fine synthetic fibers create air pockets that hold in heat, and the garment stays soft, flexible and comfortable as you move.
Made for shifting conditions, PrimaLoft Gold continues to insulate dependably even when wet. This makes it a great match for heated garments meant for active use, erratic weather and long stretches outdoors.
3M™ Thinsulate™ Insulation uses extra-fine synthetic fibers that hold warm air in while allowing moisture to pass out. The slim, efficient design gives reliable warmth with no needless weight or bulk.
Thinsulate is light, breathable and resistant to moisture, which makes it a particularly good choice for gloves, accessories and performance apparel, where warmth must be weighed against flexibility, dexterity and ease of movement.
COMPARE INSULATION
Each insulation technology trades off warmth, weight, weather resistance, and freedom of movement differently. For every Mobile Warming® product, we pick the insulation according to how and where people will wear it.
NATURAL INSULATION
Outstanding warmth at very low weight.
Clusters of natural down form lofty pockets that hold warm air.
Light, puffy, soft, and very easy to compress.
Cold weather where the most warmth for the least weight matters most.
PREMIUM SYNTHETIC

Thin synthetic fibers build an even, slim insulating layer.
Soft, light, flexible, and comfortable while you move.
Active wear, weather that is hard to predict, and wet or varying conditions.
DOWN-LIKE SYNTHETIC
The loft and softness of down with the performance of a synthetic.
Loose synthetic plume fibers fill quilted channels much as down would.
Puffy, soft, light, and compressible.
Puffer-style construction and light warmth when conditions change.
LOW-PROFILE SYNTHETIC
Warmth that is efficient, without extra weight or bulk.
Thin synthetic fibers hold insulating air inside a slim layer.
Light, breathable, flexible, and slim.
Gloves, accessories, and gear where finger dexterity counts.
How well insulation performs hinges on the material, its weight, how the garment is built, how active you are, and the conditions outdoors.
On crowded work sites, along the roadside, on night trips or in the mountains, each setting demands its own kind of visibility and readiness.
Some Mobile Warming® products team active heating with certified high-visibility design, Phoslite® retroreflective materials, and integrated RECCO® reflectors. Every technology serves a distinct purpose, making workers, riders, and outdoor enthusiasts easier to see or locate wherever they work and play.
Our heated Select Mobile Warming® workwear is made to satisfy established ANSI/ISEA and CSA high-visibility standards, protecting people who work around traffic, moving equipment, dim light, and similar hazards to being seen.
A fluorescent base fabric gives strong contrast in daylight, and retroreflective stripes placed with care bounce light back to where it came from once it gets dark. How much of each material is used, and where, is engineered into the whole garment so it fits the relevant visibility class.
Combined with built-in heating, weather-resistant construction, and features suited to the jobsite, this certified high-visibility gear keeps workers warm, easy to spot, and well equipped through cold, punishing shifts.
Phoslite® is built on millions of tiny reflective lenses fused straight onto the fabric, so the wearer stands out more after dark and when light is poor.
Headlights or any other direct light source hit the retroreflective surface, which returns the light toward where it started and creates a bright, easy-to-notice glow. Phoslite may be worked into single garment panels or spread over bigger areas, so visibility does not hinge on a few small reflective details.
Commuting ahead of sunrise, working into the night, or moving through fog, rain, or the last of the daylight, Phoslite gives you one more layer of protection in low light.
Snow and outdoor garments in the Select Mobile Warming® range include a built-in RECCO® reflector, so professional rescue crews carrying RECCO detectors are able to locate the wearer.
RECCO technology operates as a pair of components. Rescuers hold a detector that sends out a directional radar beam. Once the beam strikes the reflector sewn into the garment, the signal bounces back to the detector and helps guide the team to where the wearer is.
Because the reflector is passive, it requires no battery, no charging, no switching on, and no upkeep. After it is built into the garment it stays ready at all times, adding one more tool for professional search and rescue.
**RECCO® technology is a supplemental search-and-rescue aid. It cannot stop avalanches, ensure you will be found or rescued, or take the place of sound judgment in the backcountry, proper training, companion-rescue skills, or an avalanche transceiver with a probe and shovel.
Staying comfortable takes more than warmth. Mobile Warming™ garments blend carefully picked fabrics, purpose-built material technologies and movement-minded construction, keeping you at ease on lengthy workdays, on outdoor adventures and during regular winter days.
Controlling moisture and odor, soft fabrics to the touch, natural Merino wool blends and stretch materials that flex: every detail is chosen to make the garment feel better, fit better and work harder from morning to night.
Odorsheer™ fights odor right where it begins, curbing the multiplication of odor-causing microbes inside the fabric. Garments stay fresher during extended wear, strenuous activity, and repeated wears between washes.
At present, Fieldsheer builds Odorsheer into heated baselayers, socks, insoles, vests, and other items designed to sit close to the body or be worn for long stretches.
With Zapsheer™, conductive fibers are woven into certain fabrics and linings so static electricity can dissipate. The result is less annoying static buildup, clinging, and small shocks as you go about your day.
Less static. Easier, more comfortable layering.
Sweatsheer™ relies on moisture-wicking materials and a breathable mesh build to pull sweat off your skin and let it evaporate more quickly.
As your exertion rises and falls, Sweatsheer keeps moisture in check so the inside of the garment feels drier and more comfortable. You will find Sweatsheer moisture-wicking mesh liners in Fieldsheer heated baselayers, hoodies, jackets, and vests.
Fibers of Merino wool bring natural warmth, airflow, and moisture control within a surprisingly soft and light material. Compared with bulkier traditional wool, fine Merino blends feel comfortable even when worn directly on bare skin.
Merino wool, present in select heated socks and baselayers, keeps you comfortable as the weather and your effort level shift, and it gives active heat an efficient base to work from. Today, Merino wool blends appear in Fieldsheer heated socks as well as baselayers worn next to the skin.
