Mobile Warming Buying Guide

Reviewed by The Warming Store gear team · Updated July 2026

Mobile Warming is Fieldsheer's heated-apparel line, and its real pitch is coherence: a head-to-toe range — jackets, vests, hoodies, base layers, pants, gloves, socks, insoles, and hand warmers — designed around shared battery platforms and app control, so your heated setup grows piece by piece instead of starting over with every purchase.

One Brand, Head to Toe

Few heated brands cover this much of the body. Start wherever you're coldest: heated jackets and heated vests for the core, heated base layers and heated pants for under a shell, heated gloves and glove liners for your hands, and heated socks in merino and compression styles for your feet.

Understanding the Battery Families

Most Mobile Warming garments run on the brand's pocket-sized 7.4V packs, socks and insoles typically use small 3.7V batteries that ride at the cuff, and a separate 12V family with its own packs and chargers serves powersports and heavy-duty use. Within a family, spares and chargers generally carry over between garments — the reason to glance at the battery family on a product page before buying your second piece. Spare packs, chargers, splitters, and adapters live in Mobile Warming batteries.

App Control vs. Button Control

Many Mobile Warming pieces pair with a phone app that adjusts heat without digging under a shell — genuinely useful when the controller is buried at the hem, and some batteries even add Bluetooth control on the pack itself. Other garments use a simple onboard button. Neither is wrong; just check which a piece uses if app control is the reason you're buying.

Built for Work, Backcountry, and the Bleachers

The range splits cleanly by use. Job sites get Hi-Vis heated jackets and hoodies and hard-wearing Foreman vests and Ranger work gloves; outdoors people get Backcountry vests and jackets and camo-pattern hand warmers; everyday wearers get pieces like the Meridian jacket and even golf-specific layers. Men's and women's cuts run throughout the line, so sizing is real rather than unisex-approximate.

Base Layer or Outerwear First?

If you already own a coat you love, a Primer or Ion heated base layer worn close to the skin under it is the efficient route — the shell you trust traps the warmth the base layer makes. If you'd rather one piece do everything, start with a heated vest or jacket. Vests are the most versatile first buy: core warmth, no bulk at the arms, and they layer under almost anything.

Prices and Where to Start

Mobile Warming heated socks start from around $55, vests from around $90, base layers from around $120, gloves and glove liners from around $85, and jackets range up to around $250. Spare 7.4V batteries run from around $36 and chargers from around $15 — cheap insurance for all-day cold.

FAQs

What is Mobile Warming's app control?

Many Mobile Warming garments can be controlled from your phone rather than only by a button on the garment. In practice that means adjusting heat without unzipping a coat to reach a control, and seeing battery level before you're stranded with a dead pack. Not every product includes it, so check the product page if app control matters to you.

Do Mobile Warming batteries work across their products?

Within a voltage system, generally yes — which is the main argument for staying inside one brand. One charger, and packs you can move between a jacket, a vest, and gloves. Confirm the system on the product page before assuming a battery you already own will fit a new piece.

Is Mobile Warming the same as Fieldsheer?

Mobile Warming is Fieldsheer's heated apparel line — you'll see both names used, and gear may be labeled either way. It's the same product family, not two competing brands, so a Mobile Warming battery and a Fieldsheer-branded battery from the same system are typically the same thing.

Can Mobile Warming gear be washed?

Most of it, with the battery removed first — that part isn't optional. Cold wash, gentle cycle, air dry. No tumble drying, no dry cleaning, no ironing over a heating element. Requirements vary by garment, so check the care instructions on the product page for the specific item.
