Frequently Asked Questions
How durable is the denim?
A: The heavy cotton denim resists abrasion from tools and rough surfaces, and reinforced seams hold up to repeated hard use.
Is it quick-drying?
A: No. Denim is built for durability and structure, not fast drying. For hot, wet conditions, choose one of our quick-dry technical shirts.
Will it shrink after washing?
A: Denim can shrink slightly with heat. Wash cold and tumble dry low to minimize shrinkage.
Does it soften over time?
A: Yes. Heavy denim starts structured and breaks in to a more comfortable, personalized fit with wear and washing.
Can I wear it as an overshirt?
A: Yes. The structured cut works open over a tee as a light overshirt or buttoned on its own.
