L4 ThermoBall Midlayer Jacket - Women's

The North Face Women's L4 ThermoBall Midlayer Jacket is an adept conductor in the orchestra of your adventure. Built for the route least traversed, the L4 Jacket caters to the kind of adventures that have little room for the anything less than sure footing—after all, the sum of your parts lay covertly between calculated, frantic scrambles, decisive moves, and your ability to read between the pixelated bands of life's convoluted grayscale.

An indispensable layering piece in the innovative Summit Series line, the L4 Jacket is equipped with a vast multitude of athlete tested and alpine tailored features, ranging from its unique bottleneck quilting construction to the helmet-compatible hood. Ultimately, the L4 performs at its peak when utilized as a secondary layer when temperatures begin to dip beyond a point of comfortably cool.

The highly durable mini-ripstop nylon is manipulated to create a bottleneck design, optimal for minimizing stitch-through cold pockets, and it stabilizes insulation for efficient usage of body heat. Crafted with the efficient PrimaLoft Thermoball insulation, the synthetic clusters mimic and resemble down filaments, in turn trapping circulated body heat within small bottleneck pockets to retain warmth. An articulated pattern and female-specific design is engineered specifically for encouraging maximum mobility and protection while conducting alpine endeavors.
