This, in our humble opinion, is the perfect pair of jeans, with an extra layer of flannel safeguard against the cold, exclusive-wash look for days, and the versatility to go from the indoor to the outdoor. Really, it's the pair of jeans that'll make you wonder why you ever settled for anything less than Bonobos's classic flannel-lined.

We tested the Fireside Jean on days when the temperatures plummeted and our bodies were kept toasty longer than expected. Offering a waist-to-toe warmth, the pair packs the right amount of flair and stretch for maximum comfort. Another bonus: they're made with soft fabric that's hypoallergenic, which is well suited for sensitive skin. Plus, you can select from multiple fits including tailored, slim taper, and athletic.

What Do Buyers Say? "Super comfortable! As soon as I put them on they were my new favorites," says one bonobos.com customer.
