Versatile Men’s Long-Sleeve Flannel Shirts

A great men’s flannel is versatile comfortable. Built to last season after season, our men’s flannel shirts are a year-round go-to. They also make great gifts or hand-me-downs.

Men’s Lightweight Flannel Shirts for Daily Wear

A men’s lightweight flannel will see you through the work day and weekend chores. This staple garment is all about versatility. Wear it on its own in hotter weather, over a long-sleeve or baselayer, or add a vest for extra warmth. For cooler temps, top things off with a lightweight jacket. Whether you wear one of our men’s casual flannel shirts as a work shirt to keep the sun off, a travel top or a midlayer for changing conditions.

Warm Up with an Insulated Men’s Flannel

Dressing for a cold-weather trip or just looking to stay warm on the daily when temperatures drop? Reach for an insulated men’s flannel or men’s flannel jacket. These pieces layer well over baselayers and under heavy-duty outerwear, and have pockets for essentials. Like most of our garments and gear, our warm men’s flannel shirts are made in Fair Trade Certified™ factories.

Garments to Go with Your Men’s Cotton Flannel Shirt

Once you’ve found the right men’s long-sleeve flannel shirt, take stock of your closet. If you really need more garments, layer up with our men’s outdoor clothing. We make sturdy button-down shirts in a range of materials and styles. Not picky about colorways? Shop our Worn Wear section for button-downs that still have plenty of wear left in them. It’s a great way to save on sturdy gear.
