About Product Overview

Cold job sites don't stop because the weather turns, and this Milwaukee heated base layer is built for the guys who don't stop either. It's a long sleeve crew neck shirt made from a polyester/wool blend, sized as a kit so heat is part of the package rather than an add-on you have to hunt down separately.

Wear it under coveralls, a work jacket, or your regular gear as the layer that actually generates warmth instead of just trapping it. The wool content adds natural insulation and breathability, while the crew neck and long sleeves keep coverage where you need it during long hours outside or in an unheated shop.

This is a men's size large in charcoal, a color that won't show grime the way lighter layers do. For anyone who works outdoors through the fall and winter - on a roof, in a yard, at a loading dock - it's a practical way to add heat without adding bulk.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
