One of the most versatile jackets you'll ever add to your gear arsenal is the Arc'teryx Women's Atom LT Hooded Insulated Jacket. Wear it by itself from spring to fall on chilly adventures backpacking, climbing, or hiking, and then slide a waterproof shell over it for ski sessions in winter. When worn by itself, the Tyono shell balances wind protection with air permeable comfort so you don't overheat, and the DWR coating sheds light rainfall to help keep you dry. To keep you mobile for athletic movement, Polartec Power Stretch side panels provide a four-way stretch, plus they wick moisture, dry quickly, are durable, and breathe so you can tackle difficult summits without pulling layers off and on the whole time.
Arc'teryx also added Coreloft insulation that uses air permeable panels to ensure excellent thermal regulation. Coreloft will also still keep you warm even if it gets wet. A trim fit helps you layer over the Atom LT with ease if you need extra wind or rain protection. On days that require a little extra protection, but not a whole extra layer, throw on the adjustable, helmet-compatible StormHood to seal out the cold.
