When the mountains demand everything you've got, the Arc'teryx Beta Insulated Jacket delivers uncompromising protection for women who push boundaries in alpine environments. This all-mountain shell combines PFAS-free GORE-TEX ePE technology with strategically mapped Coreloft Continuous insulation, creating a fortress against cold, wet conditions that won't quit when you won't either. The helmet-compatible StormHood and integrated RECCO reflector system show Arc'teryx understands that serious mountain adventures require serious safety features, while pit zips let you dump heat during those grueling ascents. Whether you're navigating technical alpine routes, winter hiking through unpredictable weather, or ski touring into the backcountry, this jacket's regular fit gives you room to layer without sacrificing mobility—because the last thing you need is gear that holds you back when the summit's calling.
