Best Flannel-Lined Pants for Men, Reviewed by Style Editors

Bonobos’ flannel-lined offering is an exceptional winter-ready take on the brand’s classic chinos, which deliver optimal warmth without cramping your style. Arriving in a handful of neutral tones (green, khaki, navy, and gray), this pant is made with a sturdy—not stiff—cotton fabric and a hint of stretch, ensuring ease of movement as you’re commuting to work, sitting for long periods, or walking in cold temps. From the looks of things, it appears like a regular chino from the outside—no puffy insulation or obvious lining.

Our fashion editors prefer to dress it up with a sweater and derby shoes, but it’s versatile enough for a casual ensemble with a flannel and sneakers. The fit is pretty spot on and naturally contours to your body without feeling too tight. It’s also available in a few different fits: slim, tailored, or athletic.

We found the plaid interior feels super soft against the skin, from the moment you slip one leg in. It’s like you’re wrapping yourself in your favorite cozy blanket. Even after a long day, when you’re kicking back and winding down, you won’t be in a hurry to change into sweats—because honestly, they’re just that comfortable.

Carhartt has been churning out tough-as-nails workwear for over a century, and this utility pant follows suit. Crafted from washed cotton duck, it’s got that rugged durability with a broken-in feel right from the start. This pant is pre-softened, so we didn’t have to spend weeks breaking this bad boy in. It’s tough enough to handle construction sites, yard work, and everyday wear, while the inside feels comfortable and warm out the gate. We’ve tested this pair out in 30-degree weather, and it held up its end, keeping us from shivering.

In terms of fit, the loose cut maximizes breathability, so you never feel stuffy. Our testers noted that the generous cut in the hips and thigh gives you the freedom to squat, twist, and stretch without any kind of restriction. If you need to layer up in subzero temps, we found it’s easy to do so and not feel overheated like you’re piling lots of clothes on. Plus, the cuffs rests neatly over your work boots and the pockets can store handy tools.

If you need a work pant to handle the grind while keeping you comfortable around the clock, Wrangler has you covered. For starters, the ripstop fabric on this ranger pant is engineered to resist snags, tears, and wear—even on the most rigorous job sites. During our testing, we found it’s built to flex and move with you. The relaxed fit feels freeing and gives more wiggle room to climb ladders and crouch down.

With a lined interior, you get extra warmth and a cushioned feel that makes it perfect for chilly morning or long days spent outdoors. Reinforced seams, a roomy fit through the seat, and cargo pockets that run 13-inches deep mean you can stash your gear without sacrificing mobility. In fact, the smart design also features a hammer loop on the right side, keeping the important tools close.

We’re big fans of this pair from L.L.Bean, which we wear well into spring. Our testers have worn it with layers when the temps dip down to the teens as well as on the nights when the weather hovered around 50º F to 55º F. We also appreciate the roomy fit through the hip and thighs, which makes it a breeze to squat, bend, or simply stretch out comfortably after a long day.

While it only comes in two khaki tones, the plain front and straight leg offers a clean look that works for the office and easily transitions to a dinner date. You can pair it with a simple crewneck sweater or one with stripes to add some pizazz to your ensemble. This pair did require a longer break-in period than others, but once we really ran them in, they felt like a natural extension of our bodies.

While most flannel-lined pants lean toward casual workwear, the Hot Rydr is built to perform in the outdoors—whether you’re hiking, camping, or tackling tough terrain. Made with KUHL’s patented twill fabric, a touch of spandex, and a warm flannel lining, it locks in heat while giving you the liberty to move as you please. We found the flannel lining itself is thicker than others on the list, allowing us to stay outside for longer. Plus, the articulated knees and gusseted crotch make it actually functional for active wear, unlike some flannel-lined pants that feel super stiff and unbending.

The brand used a vintage patina dye to create a rich, weathered finish—like a pair of rugged favorites that have already put in the miles. Speaking of which, it’s a pant that has helped us survive several blizzards and cold fronts in the heart of winter. The Hot Rydr does have a full fit through the seat and thigh, so you’ve got room to move, but heads up—it does run a little small. If you’re between sizes or prefer a bit more breathing room, you might want to size up.
