Carhartt Men's Storm Defender Loose Fit Heavyweight Jacket

In this review of the Carhartt Men's 104670 Storm Defender Loose Fit Heavyweight Jacket the bottom line is simple: this is a rugged, functional outer layer for anyone who works outdoors and needs reliable wet-weather protection. Built around Carhartt's Storm Defender waterproof technology, the jacket keeps rain out while allowing sweat to escape, and its loose fit makes layering over a hoodie or sweatshirt straightforward. Reviewers praised its durability and comfort, making it a practical choice for spring and fall work days when wind and light to moderate rain are a concern.

Key Features

• Storm Defender waterproof: Waterproof, breathable technology blocks external moisture while moving internal dampness away so the wearer stays drier during active work.
• 10K/10K rating: The 10K/10K waterproof/breathability rating balances rain protection and ventilation for typical outdoor labor conditions.
• Fully-taped seams: Sealed seams provide an extra barrier at stitching lines to prevent water ingress in bad weather.
• Wind Fighter technology: Wind-taming construction reduces chill from gusts so the jacket performs well on blustery job sites.
• Mesh-lined body: A polyester mesh lining improves airflow and comfort when worn over layers for extended shifts outside.
• Storm flaps and full zip: Inner and outer storm flaps over the full-zip front add protection where most water would try to enter.

Who It's For

The jacket is aimed at tradespeople, landscapers, delivery drivers, and anyone who spends extended time outdoors and needs a durable, breathable rain shell. Its loose fit is ideal for those who want to layer a sweatshirt or hoodie underneath without restricting movement.

It is less aimed at technical outdoor athletes or mountaineers who need ultra-lightweight packs and highly compressible shells; those users should look for more performance-oriented, packable options. Likewise, if you need heavy insulation for subzero work, a jacket with a dedicated thermal fill would be a better match.

Pros & Cons

Pros

• Dependable waterproofing and breathability for light to moderate rain, supported by the 10K/10K rating.
• Durable construction and taped seams that hold up to regular outdoor use on job sites.
• Comfortable loose fit that accommodates layering and a polyester mesh lining that aids ventilation.
• Wind Fighter features reduce chill on windy days, making it versatile across seasons.

Cons

• Sizing runs toward a loose cut, so buyers seeking a trim or athletic fit may need to size down or try a different model.
• Not optimized as a packable, lightweight shell for backcountry activities where weight and compressibility matter most.

Frequently Asked Questions

Is this jacket warm enough for cold weather?
The jacket is designed as a heavyweight shell but is not heavily insulated; it performs best as an outer layer over warm base layers in cool to moderately cold conditions.

Can I wear this for heavy rain?
Storm Defender and fully-taped seams handle light to moderate rain reliably; for prolonged heavy downpours consider a fully waterproof coat rated for extreme conditions.

How does the sizing run?
Customers note the jacket runs loose to allow layering, so order your normal size if you want room or size down for a neater fit.
