Carhartt Men's Storm Defender Loose Fit Heavyweight Jacket - Rain

In this review of the Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket, the bottom line is simple: this is a work-ready outer layer for men who need dependable weather protection and room to layer. Built with Storm Defender waterproof, breathable technology and a loose cut that fits over hoodies or sweatshirts, it targets tradespeople, outdoor workers, and anyone wanting a durable rain jacket that resists wind and light to moderate rain. The jacket replaces the earlier J162 and emphasizes practical construction over fashion-forward styling.

Key Features

• Waterproof breathability: Storm Defender technology offers a 10K/10K waterproof/breathability rating so rain stays out while sweat can escape during active work.
• Seam protection: Fully-taped waterproof seams keep water from entering stitched areas for consistent wet-weather performance.
• Wind control: Wind Fighter technology reduces wind chill and helps maintain body heat on blustery days.
• Layering fit: The loose fit is cut to allow a sweatshirt or hoodie underneath without feeling tight or restricted.
• Breathable lining: Polyester mesh lining in the body improves air circulation and prevents cling when layered.
• Storm flaps: Full-zip front with inner and outer storm flaps provides extra defense against driving rain at the zipper.

Who It's For

The jacket is best for men who work outdoors or spend time in variable spring and fall weather and want a reliable waterproof layer that stands up to light to moderate rain. It suits tradespeople, landscapers, delivery drivers, and weekend hands who need a durable outer shell that fits over midlayers.

Those seeking a fashion-focused coat, an ultralight packable rain shell, or extreme cold-weather insulation should look elsewhere; this jacket prioritizes durable weather protection and layering ability rather than thin packability or heavy insulation for arctic conditions.

Pros & Cons

Pros

• Durable construction and materials give the jacket a long service life for regular outdoor work.
• Reliable waterproofing with fully-taped seams and a 10K/10K Storm Defender membrane keeps most rain out.

• Wind Fighter technology adds meaningful protection on blustery job sites.

Cons
