Carhartt Men's Storm Defender 104670 Loose Fit Heavyweight Jacket

In this review of the Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket, the bottom line is simple: this is a practical, heavy-duty rain jacket for men who work outdoors and need reliable protection without sacrificing breathability. The jacket's single biggest selling point is its Storm Defender waterproof, breathable technology, which keeps rain out while allowing sweat to escape so wearers can stay drier and more comfortable during active work. Cut with a loose fit to layer over a sweatshirt, it balances protection, durability, and everyday utility.

Key Features

• Storm Defender waterproof technology: Keeps rain from penetrating the shell while letting moisture move outward so you stay dry during physical work.
• 10K/10K waterproof/breathability rating: Provides a clear performance standard for wet-weather protection and vapor transfer under activity.
• Fully-taped seams and storm flaps: Seams are sealed and the jacket uses inner and outer storm flaps at the full-zip front to reduce water intrusion at closure points.
• Wind Fighter technology: Built to tame wind exposure so the jacket blocks chill while maintaining mobility during outdoor tasks.
• Polyester mesh body lining: Adds breathability against the skin and makes layering over a hoodie more comfortable without trapping sweat.
• Loose fit for layering: Generous cut allows a sweatshirt or midlayer underneath for added warmth in cooler months.

Who It's For

The 104670 is aimed at men who spend long hours outdoors in variable weather: contractors, landscapers, delivery drivers, and weekend DIYers who need a dependable rain jacket that stands up to daily wear. It is especially useful in spring and fall or milder winter days when wind and intermittent rain are the main challenges.

Those seeking a lightweight packable shell for occasional use or an insulated coat for cold, stationary jobs should look elsewhere. Also, if a slim, tailored silhouette is a priority, the loose fit designed for layering may feel too roomy for everyday casual wear.

Pros & Cons

Pros

• Waterproof and breathable construction that performs well against light to moderate rain.
• Durable materials and construction that hold up to regular outdoor work.
• Loose cut makes it easy to layer a hoodie or sweatshirt for added warmth.
• Sealed seams and storm flaps help keep water from entering critical points.

Cons

• The heavyweight shell is not as packable as ultralight rain shells and can feel bulky for travel.
• Not insulated, so additional layering is required for sustained cold-weather work.
