Men's Flannel Shirt


We wanted to make a flannel shirt of the highest quality, with amazing tailoring, the perfect fit and a mediumweight flannel. Doing all that in organic cotton too, well, it was a mission. But here it is, Rapanui on shirts.

The flannel weight is perfect for spring and Autumn outdoors or an evening by the beach, with a chest pocket and minimum branding. Check the herringbone detail in the fabric too.

Product Specification

The Lumberjack style flannel shirt. A timeless classic that every thinking man has in his wardrobe, ideally cut right, simple but essentially high quality - with soft fabric, but not lightweight: This item has to be a robust companion from barbed-wire fence jumping in pursuit of a semi-secret surf break through to that smart-casual meeting in the office later on. And it has to carry you through a first date or a night at the beach bar as much as that cycle commute into work.

But more than that, we wanted to make it fit so well that it felt like your favourite shirt straight away. Shirts mean a lot, and carry more expectation. So when we decided to make one, it had to be perfect. And this new supply chain had to match Rapanui's ambitious values like our commitment to sustainability, quality tailoring and at accessible prices.

And we did it. Our shirt is made from the finest 100% organic cotton flannel in Europe and cut and sewn in Portugal by hand. The medium-weight fabric is perfect for Autumn outdoors or around the office, ideally layered with one of our organic cotton t-shirts underneath.

Simply put our organic cotton flannel shirt is the finest product we've ever made.

Available in 4 sizes and multiple colours for understated style in two shades of herringbone, or full lumberjack/huntsman pattern, with tailored cuffs, stylish branding and a handy pocket to keep your pencil in. Treat yourself to one today. But be warned, you'll probably end up wanting to buy all three.

Award-Winning Traceability

It is impossible to make an ethical choice if you don’t know where clothing comes from and how it is made. Very few people do these days, even high-street stores themselves. At Rapanui you can investigate the whole supply chain and find out the details about where this item was made, who made it, and how it got here, from Seed to shop. It is called traceability.

This is a beautifully made shirt, and very good value for money.

Best flannel shirt ever!

I've never left a review for a clothing product before but felt compelled to on this one. This is a pricey but incredible quality product when you consider the ethics behind its production. The flannel weight is perfect- not too light but not too heavy either. The stand out features though are the super softness of the flannel and the great, tailored fit. I highly recommend these shirts, they look and feel even better than the photos suggest.

New favourite shirt!

Bought the brown flannel from Rapanui - it just arrived and loving it. Looks even better than the photo ; a little less yellow and a little more brown, it fits perfectly and is super soft. Well worth the 50 squid! Delivery was super fast and I even received a little handwritten note which I really appreciated.

Go get one yourself!

Ecolabel Rating

Just as your crisps tell you they have high fat or salt content, or your light bulbs tell you if they're efficient or not, we think the high street should clearly, honestly tell you how clothing is made.

After all, it’s not that people don’t care about this stuff, it’s just they don’t know. And it’s hard to find out.

Eco Label B

Our Men's Flannel Shirt has an Ecolabel rating of B

Our ecolabels basically sum up the whole picture. So an organic t-shirt ethically made in a wind powered factory, where you can trace the origins too, gets an A. One that’s made from a less sustainable material, in a conventional factory with ok ethics but unclear origins, well, that’ll get a C or a D. Really, this is the job for governments, but since they’re not doing it, and we’re not prepared to wait, we launched our own. Turns out you guys care, and responded by buying loads of our A rated stuff. Unfortunately, we still have a few shelves full of D rated pants at the warehouse. But we can’t complain, that’s the whole point: To empower you to make a choice, to turn sustainability into a market force.
