"Light weight, strethcy, comfy, great value"
"A bit more olive green then the green shown but a really comfortable long sleeve shirt"
"Love Iron & Resin, but unfortunately, this shirt had a fray and a hole. THAT being said, I reached out to customer support and they issued a gift card as the item was not longer available to re-ship. GOOD CUSTOMER SERVICE goes a long way! I'll be ordering more from them!"
"Very nice. Happy to wear it whenever it's up in my shirt rotation. Feels nice. Fits loose which is more comfortable than good looking but I like it."
"Shirt is comfortable. Fits well"
Forged in Ventura, CA in a mass produced, disposable world, Iron & Resin is a product of "one-off" culture. Where men still build, by their own hands, the craft they ride, be it water or land.
