Carhartt Men's 106673 Loose Fit Firm Duck Insulated Active Jacket body

In this review of the Carhartt Men's 106673 Loose Fit Firm Duck Insulated Active Jacket, the bottom line is simple: this is a work-ready insulated jacket for anyone who spends long hours outdoors in cold, wet, or windy conditions. The jacket's rugged duck cotton shell and layered linings deliver serious warmth and durability without unnecessary bells. The most convincing reason to buy is its combination of a flannel-lined body and quilted-nylon sleeve lining, which together keep heat where it matters while resisting wind and light moisture.

Key Features

• Quilted-flannel body lining: Provides core warmth and a soft interior layer that traps heat during prolonged outdoor use.
• Quilted-nylon sleeve lining: Makes arm movement smoother and adds wind resistance without excessive bulk.
• Attached hood with draw-cord: A flannel-lined hood that seals out drafts and adds extra protection for the head and neck on cold days.
• Multiple pockets: Two large lower-front pockets and two inside pockets keep essentials secure and hands warm on the job.
• Rib-knit cuffs and waistband: Seal out cold air at the wrists and hem for better overall insulation retention.

Who It's For

This jacket is aimed at outdoors workers, landscapers, farmhands, and anyone who needs a durable, warm layer that stands up to daily wear in chillier weather. The loose fit accommodates layering over sweatshirts or mid-layers, making it practical for variable conditions.

Those who want a sleek, lightweight packable jacket or who need fully waterproof shelling for heavy rain should look elsewhere. The fabric sheds light moisture and resists wind but is not marketed as a fully waterproof raincoat.

Frequently Asked Questions

Is this jacket warm enough for very cold workdays?
The flannel-lined body and hood plus the quilted sleeve lining provide substantial warmth suitable for cold workdays, though extreme cold may require additional layering.

Does the jacket resist rain?
The cotton duck shell resists light moisture and wind but is not a fully waterproof shell, so heavy or sustained rain will require a waterproof outer layer.

How does the fit run?
Fit is generally loose to allow layering; some customers find it runs large so checking size guidance or sizing down if between sizes is advised.
