As a midlayer or stand alone the Arc'teryx Delta Hybrid Women's Hoody is designed to keep you comfortable as you work up a sweat in the cold. Made from Polartec® Power Dry® fleece with a voided grid construction for an efficient warmth to weight ratio, heat trapping pockets, and efficient moisture movement this quick dry fabric has a smooth face that glides easily under a shell when you need added weather protection. Thumbhole cuffs keep the sleeves in place when you’re sliding them into another layer, the low profile adjustable hood fits under a helmet: bike, snow, or climbing, and the off-seam shoulders make this pack strap comfortable. The piece to choose if you’re looking for a versatile layer for cross country skiing, running, climbing, and fast hikes in cold weather this gives you wind resistance in the front and plenty of breathability on the back so you can do your best work when the weather starts kicking up cold.
