Carhartt Men's Storm Defender Loose Fit Heavyweight (Style 5Z4M)

Our review of the Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket finds it best suited for outdoor workers and anyone who needs a rugged, weather-resistant layer for cool wet days. The single biggest reason to buy is its Storm Defender waterproof, breathable technology, which keeps rain out while allowing sweat to escape so the wearer stays drier during physical tasks. Cut in a loose fit to accommodate a sweatshirt or hoodie, this jacket balances durability and comfort without feeling overly bulky.

Key Features

• Storm Defender waterproof technology: Stops water from getting in while still letting sweat escape, making it practical for active outdoor work.
• 7.3-ounce 100% nylon oxford shell: Provides a durable outer layer that stands up to abrasion on job sites and in rough weather.
• Nylon taffeta sleeve lining: Lets the jacket slide on and off easily, useful when layering over work shirts or hoodies.
• Wind Fighter technology: Cuts wind chill so the jacket preserves body heat on blustery days without adding much weight.
• Polyester mesh body lining: Increases breathability inside the torso so the jacket does not trap overheating during activity.

Who It's For

This jacket is aimed at men who work outdoors in changing weather or anyone seeking a dependable rain and wind layer for spring and fall. The loose fit is ideal for those who need to wear insulating layers beneath, such as a sweatshirt or light fleece, and for people who value rugged construction and simple, functional features.

Those who want a lightweight packable shell for travel, an insulated coat for subfreezing temperatures, or a highly technical mountaineering shell should look elsewhere; this jacket is designed as a heavyweight, work-ready outer layer rather than a minimalist packable or extreme cold weather garment.
