Iron and Resin Sierra Flannel Shirt

103637

See the Iron and Resin collection here

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 shirt.

This is one of those pieces that makes you question what you did before. Made from a 240g twisted cotton, and outfitted with our custom plaid flannel design, this is a piece that actually feels as good as it looks.

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.

High Quality

This is a high-quality, soft, thick cotton shirt with metal buttons. It fits true to size, is very comfortable, and washes well. I would definitely buy again from Natural Man, whose service was A1.

Iron and Resin

I'm so pleased to find this brand. I have a muscular body. Having lifted weights for 40plus years. And finding quality and nice looking clothes is not easy. I have worn the shirt and a duck canvas shirt from Iron and Resin today and it looked amazing. I even had a compliment from a young lady how smart I look!

Iron and Resin Sierra Flannel Shirt

The now usual excellent service from Mark and Natural Man. I’ve got most of the Stormy Kromer flannel shirts, so I thought I’d try one of these, Ye Gods! They are a quantum leap in quality and comfort. Time will tell how they bear up in terms of washing and long term use, but I’ve washed this a couple of times and it’s like new. If you’re dithering, don’t!
