Work Bibs

A bib overall covers the ground a jacket leaves open: chest, back, and legs in one piece, with no gap at the waist when you bend, kneel, or reach overhead. Overlook Boots stocks work bibs from Ariat, Timberland PRO, and Portwest, in insulated, unlined, and flame-resistant builds.

Insulated or Unlined

Insulated bibs are the cold-weather answer. Ariat's Rebar DuraCanvas Stretch bibs carry 110 grams of insulation and Timberland PRO's Gritman carries 100 grams, enough for winter work without the bulk that makes climbing and kneeling awkward. Unlined bibs, including the Rebar DuraCanvas unlined and Ariat's unlined flame-resistant canvas, suit shoulder-season work and anyone who runs warm and wants the coverage without the added warmth.

Flame Resistant Bib Overalls

Much of this collection is flame resistant, which reflects where bibs actually get worn: oil and gas, utilities, and electrical work. Ariat's FR Insulated Overall 2.0 is water repellent, and there is an FR hi-vis waterproof bib for crews that need visibility and flame resistance at once. Portwest covers the same ground with the DuraDuck quilt-lined and Bizflame insulated FR bib overalls. As with any FR program, the whole layering system has to be rated, since a non-FR bib worn over an FR shirt undoes the protection.

Sizing and Layering

Bibs go on over your work clothes, so account for what you will be wearing underneath. An insulated bib over a heavy hoodie needs more room than an unlined bib over a t-shirt. Sizing runs differently between brands, so check the size chart on the individual product page rather than assuming your jeans size carries over.

Frequently Asked Questions

What is the difference between bib overalls and coveralls?

Bib overalls cover your legs and chest and are held up by shoulder straps, leaving your arms and upper back open. Coveralls are a full one-piece garment with sleeves that covers you from ankle to neck. Bibs run cooler and are far easier to get on and off over boots, which is why most people layer a bib with a jacket instead of wearing coveralls.

What does 110G insulation mean?

The number is the weight of the insulation in grams per square meter, so a higher number means more insulation and more warmth. The 100 to 110 gram range found on Ariat's Rebar bibs and the Timberland PRO Gritman is a working winter weight, warm enough for cold-weather job sites while staying flexible enough to kneel and climb in. Heavier weights add warmth but cost you mobility.

Do I need flame-resistant bibs?

You need them if your employer or site runs an FR program, which is standard in oil and gas, utility, and electrical work. When FR is required it applies to the whole layering system, so a non-FR bib worn over an FR shirt cancels out the protection underneath. Ariat and Portwest both make FR bibs in insulated and unlined versions.

Should I size up when buying work bibs?

Size for what you will wear underneath rather than for your body alone. An insulated bib worn over a hoodie and a work shirt needs noticeably more room than an unlined bib over a t-shirt. Brand sizing also varies, so check the size chart on the product page before you order.

Which bibs hold up in wet conditions?

Ariat's FR hi-vis waterproof bib is the pick when you need to stay dry, and the FR Insulated Overall 2.0 is water repellent for lighter exposure. Water repellent sheds a shower and wet snow, while waterproof is built for sustained rain and standing water. Match the level to how long you are actually out in it.

Can I wear a bib over insulated work pants?

You can, though most people find an insulated bib on its own is a better system than stacking an unlined bib over insulated pants. Two layers of heavy fabric at the thigh restricts movement where you need it most for climbing and kneeling. If you know you run cold, an insulated bib over a base layer usually wins on both warmth and mobility.
