Arc'teryx Nuclei Hoody -

The Arcteryx Women's Nuclei Hoody is a cozy mid-layer with strategically mapped insulation to maximize warmth while minimizing weight. The synthetic Coreloft™ is more dense throughout the core and less dense in the sleeves and side panels. The end result is a lightweight, mobile jacket that is so trim it'll feel like wearing a comfy old sweatshirt. I know you've been out in the woods or out on the wall when temperatures dropped and you longed for some effortless warmth. With the included mini stuff sack you can easily keep the Nuclei Hoody at arms length for just this situation. Or to use as a pillow. Or to dress a snowman in a pinch.

Arc'teryx redefined climbing jackets with its Women's Nuclei Hooded Insulated Jacket. Airetica fabric is tightly woven in the Nuclei to give you a super durable jacket that doesn't add much weight to your gear. Arc'teryx added 80g insulation in the body for core warmth that's breathable and thermally efficient, and 60g insulation in the sleeves and side panels for less bulk when you send pitch after pitch.
The Nuclei has a trim fit that keeps your freedom of movement in mind while lowering bulk at the same time. Its hood cinches across your head tightly so you can strap a helmet to your noggin comfortably. The interior stow pocket lets you stuff the jacket in itself and clip it to your harness, and Arc'teryx included a mini stuff sack for your backpacking days. An adjustable drawcord allows you to tighten the jacket down when winds try to get between you and your jacket. You can barely notice the hand pockets because the zippers are tiny and hidden from plain view.
