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

Our review of the Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket finds it best suited for men who work outdoors and need a dependable, layerable outer shell. The single biggest reason to buy is the combination of true waterproof protection and breathability: the jacket uses Storm Defender technology with a 10K/10K waterproof/breathability rating and fully-taped seams, so it keeps rain out while letting sweat escape when the pace picks up. It wears comfortably over a sweatshirt thanks to the loose fit and stands up to wind and repeated use.

Key Features

• Storm Defender waterproof: Waterproof, breathable technology prevents rain from entering while moving moisture away from the body so you stay drier during active work.
• 10K/10K rating: A balanced 10K waterproof and 10K breathability rating provides year-round protection for light to moderate rain and steady airflow for comfort.
• Fully-taped seams: Seams are fully sealed to stop water intrusion at stitch lines, improving overall waterproof performance on wet days.
• Wind Fighter technology: Wind taming construction reduces chill from gusts, making the jacket useful in blustery conditions.
• Layerable loose fit: The loose fit accommodates sweatshirts or midlayers, so you can add insulation underneath without restricting movement.
• Practical closures and lining: Full-zip front with inner and outer storm flaps and a polyester mesh body lining give secure closure and added breathability.

Who It's For

The jacket is aimed at men who need a hard-wearing rain and wind shell for outdoor work or utility tasks, particularly in spring and fall. It suits tradespeople, landscapers, or anyone who spends hours outside and needs a jacket that sheds light to moderate rain while allowing sweat to escape.

Those who want a lightweight packable rain shell for occasional use or an insulated parka for winter extremes should look elsewhere; this model prioritizes waterproof breathability and layering capability rather than heavy insulation or minimal pack size.

Pros & Cons

Pros

• Reliable waterproof protection with fully-taped seams for wet-weather confidence.
• Balanced breathability so perspiration is less likely to accumulate during active work.
• Durable construction and a loose fit that accommodates midlayers for added warmth.
