15 Jeans That Will Actually Keep You Warm This Winter

We've officially reached that time of year when the simple act of stepping outside results in numb appendages and the threat of frostbite. While the standard hat, mittens, and scarf combination remains our first line of defense, we're pleased to report that we've found a surprisingly sleek source of undetectable armor for our legs: fleece-lined jeans.

Nestled somewhere between your standard denim and ski apparel, fleece-lined jeans offer an added layer of protection while appearing completely normal to the untrained eye—no bulky layers or heavy fabrics here. Most importantly, fleece-lined jeans are actually warm. You feel as if you're bundled up for the ski slopes, motivating you to brave your morning commute December through March.
