Is the Key insulated bib overall warm enough for winter?

It has 4 oz polyfill, which suits fall and mild winter work. For deep cold, layer underneath or step up to a heavier insulated bib.

Does it run true to size?

It has a relaxed fit and owners report it runs roomy. If you are between sizes or plan light layering, consider sizing down.

Are the knees and seat waterproof?

Yes. Key puts a waterproof barrier at the seat and knees, though the rest of the cotton duck shell is not waterproof.

Can I get it on over boots?

Yes. One-way leg zippers run to the knee, so you can open the legs and pull the bibs on over work boots.

How should I wash it?

Machine wash it and follow the care label. Avoid fabric softener, which can cut down on the duck's water resistance.

Workwear tends to drop in late summer and early fall before cold-weather demand peaks. The best new price was $122.10 at All Seasons Uniforms as of November 8, 2026.
