Experience warmth, freedom, and rugged durability with the Milwaukee M12™ Heated AXIS™ Vest (Model M300B‑21). Designed for the coldest moments, this smart vest delivers powerful heating without compromising mobility—ideal for work, outdoor adventures, or everyday layering when the chill sets in.
We at Bering’s believe your gear should work as hard as you do. That’s why this vest features HEXON HEAT TECHNOLOGY™, offering rapid heat‑up and superior coverage across two key zones: chest and back. Made from AXIS™ Ripstop fabric, it’s engineered to resist tears, fend off wind and water, and still remain compressible enough to wear over or under outer layers. With generous run times across three heat settings—low, medium, and high—you stay warm when you need it most without constantly recharging.
Why you’ll love the Heated AXIS Vest:
- Two heat zones (chest + back) powered by M12 battery system—fast, even warmth where it counts.
- All‑day run time: approximately 8 hours on low, ~4 hours on medium, and ~2 hours on high settings.
- Durable AXIS ripstop polyester fabric with wind‑ and water‑resistant finish, plus thoughtful design like a battery pass‑thru pocket (front or back) and adjustable waist to seal in warmth.
Since 1940, our family‑run store has been all about gear that lasts. The M300B‑21 vest reflects that commitment—combining innovative heating tech with rugged build quality so you can stay warm, hands‑free, and focused on the job.
Whether braving early morning cold, cracking the frost on your windshield, or needing that extra layer of cozy on chilly job sites, this vest is your go‑to for dependable warmth without the bulk. Layer it, move in it, live in it.
