Is this coat actually flame-resistant?

Yes. Carhartt builds it as flame-resistant cotton duck workwear. Check the garment label and your employer's hazard standard, since FR cotton is not the same as arc-rated gear for every electrical task.

How does it fit compared with a regular Carhartt coat?

It runs in Carhartt's traditional work fit: roomy through the chest and long in the body to cover the seat. Most buyers take their usual Carhartt size, and layering a hoodie may push some to size up.

Is it warm enough for winter?

It blocks wind and holds heat well for a cotton duck coat, but it is not a heavily insulated parka. In deep cold, plan on layering underneath or choose a lined FR style.

Can I wash it normally?

Wash it as FR clothing, following the care label: mild detergent, no fabric softener or bleach, and no products that leave residue on the fabric. Residue and harsh chemicals can reduce flame resistance.

What is the two-way zipper for?

It lets you unzip from the bottom as well as the top, so the coat opens up when you sit, drive or climb. That keeps the hem from bunching while the chest stays closed.
