The wool shirt is one of those pieces that has been around for centuries, and for a damn good reason. It has unparalleled insulating properties that make it the ultimate transitional piece and an even better layering piece under a rain-proof shell. We wanted to create our own take on this timeless masterpiece. Amping it up with a quilted polyester liner and our custom blend of a heavyweight wool & polyester blend, this one has become an immediate staple in our winter wardrobe.

Excellent Shirt jac

"This was my third purchase from InR and they continue to not disappoint. This feels like a lightweight version of my Makinaw cruiser with a few caveats. Lighter and easier to wear when it's not frigid, while maintaining very high quality just using a wool/polyester blend. Size chart is on point which makes their stuff easy to buy, I really appreciate that. Overall everything I've received from InR has restored my faith in quality clothing, highly recommended, I would just encourage them to continue exploring more items being made in the USA if possible although that certainly comes with price considerations."

"Great quality, feels soft yet very tough."

More like a jacket than a shirt

"This is definitely way thicker than I expected. I'm not mad about that as I bought this for the colder weather in the Northeastern US. Seens lie it'll be warm. The fit is slightly on the larger side, which I'm happy about because it'll allow for a hoodie or sweatshirt underneath for layering. The fit is kinda odd. . . . the shoulders look big and bulky and the arms/biceps feel kinda restricted. I feel like with a wool blend, this thing well break-in a bit and be more flexible over time. Overall I plan on wearing the heck outta this "shacket. " Quality seems top notch."

Peak Shirt

"I am 5'10" and weigh 235. I purchased a double X and it was not big enough for me. Now I have purchased the triple X and it is about the same exact size as the double x, which now I have 2 brand new shirts I have to lose some weight to fit into. I feel both of them should be larger in size. I'm not that big of a guy."

— Daniel Z. (5/5)

"This piece is awesome. It's a little too warm to wear right now, but the fit is great! Look is even better in person"

— Michael (5/5)
