Goodfellow & Co Men’s Long Sleeve Flannel Shirt
We designed this flannel to be the shirt you reach for when the temperature drops and you need something that works from weekend errands to casual Friday. The brushed cotton fabric gets softer with every wash while maintaining the structure you need for a polished look. Our tailored fit strikes the balance between comfort and shape—relaxed through the shoulders and chest without feeling boxy.
The classic plaid patterns anchor your wardrobe rotation season after season. We chose colorways that layer under jackets in fall or stand on their own in spring. Button-down collar and chest pocket add functional details without overcomplicating the design.
Construction & fit details

Fabric & Construction
We start with mid-weight cotton flannel that’s been brushed on both sides to trap warmth without bulk. The weave density hits the sweet spot for fall and spring—substantial enough to block wind on cool mornings but breathable enough that you won’t overheat indoors. Each shirt goes through a pre-wash treatment before it ships, which means the fit you try on is the fit you keep.
The plaid pattern is woven, not printed, so the colors run through the entire fabric. Bar-tack stitching reinforces stress points at the pocket corners and underarm seams. Double-needle stitching on the hem and cuffs prevents fraying after repeated washes.

Sizing & Fit
Our tailored fit is cut closer to the body than a traditional flannel without feeling restrictive. Measure across the chest at the fullest part—if you’re between sizes, we recommend sizing up if you plan to layer over thicker base layers like henley shirts. The shoulders are set to follow your natural line rather than extending past it.
Length & Proportions
The shirt measures 29 inches from high point shoulder to hem in size medium, designed to hit mid-hip whether you tuck it in or leave it out. Sleeve length is sized for a clean break at the wrist when your arms are at your sides. The tail hem has a slight curve but no dramatic drop, which keeps it from bunching when you move.
Styling & Layering
Wear this flannel as an outer layer over our everyday crewneck tees during transitional weather or button it under a field jacket when temperatures drop further. The collar works open or buttoned to the top—both look intentional. Roll the sleeves to show contrast cuffs or leave them down with the button tabs fastened.
The color palette spans earth tones and cool grays that pair with denim, chinos, or joggers. We avoid overly bright or saturated plaids in favor of muted combinations that fit into a minimalist wardrobe. Each pattern includes at least one neutral tone so you can anchor it with black, navy, or olive pants.

Common Questions About This Flannel
The shirt is pre-washed before it ships, which minimizes shrinkage during regular care. We recommend washing in cold water and tumble drying on low heat to maintain the original fit. Some customers report minimal shrinkage in length if dried on high heat, so stick to low or hang dry if you’re between sizes.
The brushed cotton flannel provides moderate warmth suitable for fall and mild winter days. For colder weather, we recommend layering it over a thermal base layer or under a heavier jacket. The fabric traps heat close to your body without being heavy, so it works well as a mid-layer in a three-piece outfit.
Our tailored fit follows your natural body shape more closely than a traditional boxy flannel. It’s cut closer through the chest and waist without restricting movement. If you prefer a looser, more relaxed feel with extra room for layering, size up one size from your usual measurement.
Yes, the hem length is designed to look intentional whether you tuck it in or leave it out. The tail hem has a slight curve that prevents bunching at the sides, and the overall length hits mid-hip on most body types. The cut is clean enough for casual work settings and relaxed enough for weekends.
Turn the shirt inside out before washing and avoid washing it with rough fabrics like denim or items with zippers. Wash on a gentle cycle with cold water and tumble dry on low heat. Fabric softener can actually increase pilling by breaking down fibers, so skip it. After a few washes, any minor pilling can be removed with a fabric shaver.
We offer the Goodfellow & Co men’s long sleeve flannel shirt in several classic plaid combinations including navy and gray, burgundy and black, olive and cream, and charcoal and white. All patterns use muted earth tones or neutrals that coordinate with denim, chinos, and dark joggers. Seasonal colorways may be introduced during fall releases.
The button-down collar has enough structure to hold its shape under a jacket collar but isn’t stiff or uncomfortable. There’s no interfacing or heavy starch—just the natural weight of the cotton flannel. The collar softens further with washing but maintains enough body to look polished when you button it all the way up.
