Carhartt Men's 104670 Storm Defender Heavyweight Jacket - Waterproof

In this review of the Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket, the bottom line is simple: this is a dependable, weather-ready outer layer for anyone who works outdoors and needs protection without sacrificing breathability. Built with Carhartt's Storm Defender waterproof, breathable membrane and a loose cut for layering, the jacket aims to stop rain and hold up to daily wear while allowing sweat to escape. The single biggest reason to buy is its combination of reliable waterproofing and practical workwear durability that performs well in light to moderate wet conditions.

Key Features

• Waterproof Breathability: Storm Defender technology with a 10K/10K rating keeps rain out while letting sweat escape so the wearer stays drier during active work.
• Seam Protection: Fully-taped waterproof seams add an extra barrier against water intrusion at vulnerable stitch lines for true on-the-job protection.
• Wind Control: Wind Fighter technology tames gusts to help retain warmth and reduce chill when working in exposed conditions.
• Breathable Lining: Polyester mesh-lining in the body improves air circulation and comfort when layering over a sweatshirt or hoodie.
• Secure Closure: Full-zip front with inner and outer storm flaps helps keep water out of the zipper area for dryer interior layers.
• Loose Fit for Layering: The loose cut is designed to fit over midweight layers so you can adapt the jacket to cooler temperatures.

Who It's For

The 104670 is aimed at tradespeople, landscapers, and anyone who spends long periods outdoors in variable weather and needs a durable, waterproof shell they can layer over sweatshirts. It suits users who value straightforward, no-frills performance fabrics that balance waterproofing with breathability.

Those who want an ultralight packable rain jacket or a heavily insulated winter parka should look elsewhere; this jacket is a heavyweight work shell meant for spring, fall, and mild winter layering rather than extreme cold alone.

Pros & Cons

Pros

• Reliable waterproofing with a 10K/10K Storm Defender membrane keeps moderate rain out.
• Durable construction and fully-taped seams stand up to daily work use and abrasion.
• Loose fit and mesh lining allow comfortable layering and improved breathability during active tasks.
• Wind Fighter technology reduces chill when working in windy conditions.

Cons

• Not a replacement for a heavy insulated parka in severe cold; best used with layers for warmth.
• Design and weight reflect workwear durability, so it is not as packable or lightweight as minimalist rain shells.
