Carhartt Men's 104670 Loose Fit Heavyweight Jacket - Waterproof

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 reliable, weatherproof layer that can be worn over a sweatshirt. The single biggest reason to buy is its Storm Defender waterproof, breathable technology, which keeps rain out while letting sweat escape, making it far more comfortable for active jobs than a non-breathable rain shell. This jacket replaces the J162 and is cut with a loose fit so it layers easily while remaining rugged enough for daily use.

Key Features

• Storm Defender waterproof breathable: Stops water from getting in while moving sweat away so the wearer stays drier during physical work.
• 10K/10K waterproof/breathability rating: Offers a balanced protection level against light to moderate rain while still allowing airflow for comfort.
• Wind Fighter technology: Tames wind chill so the jacket reduces the cold effect of gusts on exposed job sites.
• Fully-taped seams: Keep seams sealed against water intrusion for more reliable wet-weather protection.
• Polyester mesh lining: Adds internal breathability and comfort while making layering over a hoodie easier.
• Full-zip with storm flaps: Inner and outer flaps block driving rain at the front zipper for improved sealing.

Who It's For

This jacket is aimed at men in construction, landscaping, delivery, or other outdoor trades who need a durable rain jacket that can be layered over work sweatshirts and mid layers. Its loose fit and heavyweight build make it practical for colder spring and fall days when light insulation plus a waterproof shell is required.

Shoppers seeking an ultralight packable rain shell or a heavily insulated winter parka should look elsewhere; this model prioritizes waterproofing and rugged durability over packability and heavy thermal insulation.

Pros & Cons

• Waterproof and breathable Storm Defender fabric keeps rain out while reducing sweat buildup.

• Loose fit allows layering, so the jacket works well with hoodies and mid layers for added warmth.

• The heavyweight, loose construction is not ideal for those wanting a slim or easily packable rain shell.
