Frequently Asked Questions

Is this a warm enough high-visibility winter coverall for extreme cold?

Yes. This hi-vis winter coverall is built with 10.5 oz (350 GSM) cotton duck and 6.5 oz (220 GSM) quilted insulation, giving it serious warmth for sub-zero conditions. It’s designed for outdoor winter work.

Is cotton duck better than polyester for workwear?

For many trades, yes. Cotton duck is more durable, abrasion-resistant, and holds up better against sparks, rough surfaces, tools, and heavy machinery. It’s a preferred fabric for heavy-duty insulated workwear used by construction, maintenance, and industrial crews.

Does it include a hood?

No, a hood is sold separately. The collar includes snap attachments compatible with Pioneer 539/538 hoods.

What makes this different from cheaper winter coveralls?

This model provides:

• Premium cotton duck (not thin polyester)
• Quilted insulation for better warmth retention
• Double-stitched reflective tape for longer durability
• Reinforced 2-way brass zippers
• Hip-to-ankle leg zippers for easy boot access
• 6 functional pockets for tools and gear

It’s built for professionals who rely on heavy-duty insulated coveralls for full-shift protection.

Can I wash this quilted cotton duck coverall in a machine?

Yes, but follow the care instructions to protect the insulation and reflective tape:

• Machine wash cold
• Use mild detergent
• Do not bleach
• Hang to dry (do not high-heat tumble dry)

Proper care extends the lifespan of the reflective safety tape and the cotton duck shell.

How does the sizing fit?

It has a regular-to-relaxed fit designed for layering over work clothes. Most users order their usual size, but if you wear thick winter layers underneath, consider sizing up.

Is this insulated coverall flame-resistant?

No. It is not FR-rated. It is built for warmth, visibility, and durability, but not for flash-fire or arc-flash environments. If you need FR-rated hi-vis workwear, Cleanflow carries Pioneer FR high visibility options as well.
