The Arc'teryx Aestas Crew is the fleece every female climber needs in her kit – a technical mid-layer that moves with you from gym sessions to granite walls without missing a beat. Built with Polartec Power Air Hardface fleece, this women's climbing fleece combines the warmth you crave with a smooth exterior face that layers seamlessly under your shell while resisting the inevitable scrapes that come with sending your project. The articulated patterning and strategically placed shoulder seams mean your range of motion stays unrestricted whether you're reaching for that next hold or shouldering a pack for the approach, while the 73% recycled polyester construction proves you don't have to choose between performance and protecting the places you love to climb. At 350g, it's light enough for long alpine days but substantial enough to keep you comfortable during those post-climb hangouts when the sun dips behind the crag.
