Built to be lived in, the Slab Shirt carries the tradition of West Coast work ethic and laid-back grit. It’s the kind of flannel that’s seen morning fog roll off the Pacific, been tossed over a hoodie when the winds shift offshore, and draped over a passenger seat still sandy from the day before. This shirt is less of a garment and more of a uniform - for those who keep it local, keep it simple, and keep showing up.

"Another fantastic quality product. As with the other IR flannels I already own, super happy with purchase. Gen X so I remember when most things were manufactured to last, now referred to as “heritage” with quality footwear for example. IR flannels are heritage standard!"
"What a great shirt. It’s heavy and stiff, feels like armour. It will stand on a table like someone is wearing it. Wash it, wear it, break it in."
"The shirt looks even better in person!"
"It seems like a good-looking shirt with a sturdy, lived-in vibe rather than anything fussy."
"the Slab flannel shirt. . . handsome, heavy and ridiculously well made. I got the brown, kind of wish i'd gotten the black as well. Typically whatever you buy from I & R will make you very happy. 🔥⚡️💥"
"Straight up, these I&R flannels are everyday, anytime go to shirts."
