What to look for when searching for the best flannel-lined jeans

Material

Clearly, you want the best flannel-lined jeans to be made of denim and soft flannel. As for composition, 100% cotton is great, but a blend with some spandex stretch or other innovative fabric composition will take your denim the extra mile in terms of movement. Believe it or not, cotton blended with a synthetic fiber like polyester adds tons of durability. 

Style

If you’re riding a motorcycle, chopping wood, or doing construction, then a slim style simply won’t do. Pay attention to how the pants fit in the seat and hug the leg for a broader range of movement. Regular, cowboy cut, and relaxed styles will give you a higher range of motion. Straight leg cuts will sit closer to the body and create one long line from the hip to the ankle. 

Fit

Like style, fit can depend on your personal preference. But overall, it determines how well the clothes hug or sit away from the body. Does the waist feel like it’s slipping or pinching on your natural waistline? Hint: those aren’t good signs. Overall, most guys prefer a relaxed fit that stands just away from the body but doesn’t bunch, hug, or sag.
