Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket in

Our review of the Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket finds it best for anyone who works outdoors and needs a dependable, weatherproof outer layer. The single biggest reason to buy is the Storm Defender waterproof, breathable technology, which keeps rain out while allowing sweat to escape so the wearer stays drier during active work. Cut with a loose fit, it accommodates a sweatshirt or hoodie underneath, making it a practical choice for cooler, wet days on site or for routine outdoor tasks.

Key Features

• Waterproof/Breathable: Storm Defender technology delivers a 10K/10K waterproof and breathability rating so the jacket blocks rain while moving moisture away from the body.
• Seam Protection: Fully-taped waterproof seams prevent water intrusion at construction points, adding reliable protection in steady showers.
• Wind Resistance: Wind Fighter technology tames wind chill so cool breezes are less likely to compromise comfort on the job.
• Layering Fit: The loose cut provides room to layer a sweatshirt or hoodie for added warmth without restricting movement.
• Breathable Lining: Polyester mesh lining in the body improves airflow and prevents a clammy feel when working at moderate exertion.
• Secure Closure: A full-zip front with inner and outer storm flaps keeps water out of the zipper area for better overall protection.

Who It's For

This jacket suits outdoor workers, tradespeople, and anyone who spends time outside in light to moderate rain and wind. Its loose fit and breathable membrane make it a practical shell for layering over midweight garments, which is useful during spring and fall when conditions vary through the day.

It is not intended as an insulated winter parka; buyers seeking heavy insulation for extreme cold should look for a dedicated insulated coat. Also, those who need a very lightweight packable rain jacket for travel may prefer a less heavyweight option.
