Size Recommender
We knew the second we slid the Sierra Shirt on that this wasn't going to be one of those flannels that just sat idly by in your closet... No, this is not that type of shirt. This is one of those pieces that makes you question what you did before. Made from a 100% cotton twill, and outfitted with our custom plaid flannel design, this is a piece that actually feels as good as it looks. The only problem is choosing which color to go with. Perhaps all of them?

HOW IT FITS
The Sierra Shirt runs true-to-size; however, if you tend to be between sizes or prefer a roomier fit, we would recommend ordering a size up.
Our goods are meant to be worn in, not out. With the correct care, we want our customers to be able to treat their gear with the tough love it was intended to take. Take a look at our Wash & Care Guide to keep your goods performing for a lifetime.
Good things never go out of style. And great things get better with the passage of time.

"Comfortable material I can wear all day - sleeves down or rolled up. Love the metal buttons too."
"This garment fits well and the material is always of good quality. Its durable fabric and colors give it a flawless look. The sizing is what you'd expect from Iron & Resin, and this t-shirt is no exception."
"I'm becoming a broken record because I have nothing new or innovative to say about Iron and Resin shirts - they are always well built, and the sizing is remarkably consistent. I'm 5'10", 175, and prefer a slightly larger-than-usual overshirt. . . and all the I&R shirts, from chambray to flannel, are excellent for me in an XL. I guess that would suggest one should consider sizing up in shirts. . . their jackets are pretty true to size but I find the shirts a little short, so I size up. . and I own nearly every one of their shirts. Love them, and YOU WILL TOO"
"Instant compliments on wearing this shirt. Thick. Soft. Good length. Buy it. No regrets."
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.
