The Arc’teryx Beta SL Jacket is the kind of outerwear that flips bad forecasts into adventure invites, your go‑to shelter against wind, rain, and unpredictable skies. As the lightest in the Arc’teryx Beta line, this Arc’teryx Beta SL jacket may feel featherweight, but its PFC free GORE‑TEX e PE membrane delivers serious strength. Add in C‑KNIT backer tech for comfort and breathability, plus a helmet‑compatible Storm Hood and RECCO reflector, and you’ve got an Arc'teryx jacket Beta SL style designed to thrive in the elements. 100% Nylon 3L GORE-TEX e PE with C-KNIT™ Backer Waterproof & Windproof Adjustable Velcro® Cuffs RECCO® Reflector Helmet Compatible Storm Hood™ Pit Zippers Internal Chest Pocket 2 Zip Hand Pockets Style Code: X000009684-002291
