100% cotton. Flannel fabric. Full button fastening. Two patch chest pockets. One interior chest patch pocket. Buttoned cuffs. Curved hem. Regular fit. Adsum’s Workshirts are true things of beauty and this No Flap Flannel number is no different. There’s a bunch going on behind the scenes which really push this to wardrobe workhorse status (like the triple-stitching and bullet-proof buttons), but even if you’re not bothered about that stuff, you can’t deny that this is one eye-catching garment indeed.
