Sherpa is a soft, textured synthetic fleece material with a pile surface that mimics the texture of sheep's wool; it is the lining used in many premium work shirts, jackets, and boots for cold weather insulation. A sherpa-lined flannel shirt has a layer of this soft fleece bonded to the interior of the flannel shell, adding substantial warmth beyond what the flannel alone provides. A standard heavyweight flannel handles approximately 40-55°F comfortably. A sherpa-lined version extends that range down to approximately 25-35°F depending on activity level. The sherpa lining makes this shirt function as a light jacket rather than simply a shirt.

Rothco's buffalo plaid uses this traditional heavy-duty workwear design. The extra heavyweight designation means this flannel uses a fabric weight above standard heavyweight flannels: 8 oz or heavier cotton flannel that provides noticeable substance and warmth beyond what commercial flannels typically offer.

Yes, and this is specifically noted in the product description. The sherpa-lined, extra-heavyweight construction is substantial enough to wear as an insulated overshirt or light jacket in cold, dry weather, eliminating the need for a separate jacket in many conditions. Button it over a T-shirt or base layer for a complete cold weather casual outfit. The sherpa lining facing outward when the shirt is unbuttoned and worn open adds visual texture that works well as outerwear styling.

The machine washes on a gentle cycle in cold or warm water. Tumble dry on low heat; high heat can cause the sherpa lining to pill or mat, and can shrink the 100% cotton flannel shell more than the lining accommodates. Do not iron the sherpa side. The flannel shell can be lightly ironed on a medium cotton setting. Pull the shirt gently into shape while still damp if the sherpa backing causes any distortion after washing. For heavy soiling on the cotton shell, pre-treating the stain before washing helps prevent the stain from setting into the thick fabric.
