Arc’teryx Alpha SV vs Beta AR: women’s jackets compared
Choose the women’s Alpha SV for climbing-focused chest storage and its StormHood. Choose the women’s Beta AR if hand pockets and a DropHood better suit your mountain use. Both current jackets have a regular cut, GORE-TEX PRO ePE construction and pit zips.
Based on 243 included owner reviews. Owner evidence spans multiple revisions; current specifications do not describe every reviewed jacket.
The differences that matter
The Alpha SV places two main pockets on the chest and adds internal dump pockets and a bicep pocket. The Beta AR uses two hand pockets. A harness or pack waistbelt can change which layout is convenient, so compare pocket access with that equipment on.
Arc’teryx lists the women’s Alpha SV at 420 g and Beta AR at 395 g. The Alpha uses a 100-denier face, while the AR combines 80- and 100-denier fabrics. Those specifications describe the constructions, without establishing the lifespan of either finished jacket. The hood and storage are stronger reasons to choose than the small listed weight gap.

Which should you choose?
Choose Alpha SV when accessible chest storage and the StormHood suit your climbing setup. Choose Beta AR when hand pockets and its separate-collar DropHood work better with your layers. Try the hood with your helmet and check arm movement. The women’s owner findings below should guide that fit check; the men’s jackets do not supply the missing answer.
