The Arc'teryx Beta AR Jacket is the toughest shell in the Beta lineup, built for sideways rain and summit pushes where bail isn't an option. This all-mountain hardshell uses a smart hybrid of GORE-TEX PRO ePE fabrics with beefier 100D material at the shoulders (where your pack sits) and lighter 80D through the body to keep weight in check without sacrificing protection.
