Arc'teryx has a whole series of Beta Jackets ranging from the SV (severe weather) to the SL (superlight). The Beta AR Jacket is Arc'teryx's All-Round model made for the versatile mountaineer who climbs alpine all summer and skis the backcountry all winter. Its three-layer construction includes a Gore-Tex Pro laminate for incredible waterproofing when you're skiing powder and enhanced breathability when you're on the ascent. Although not the lightest Beta, that belongs to the Beta SL, this jacket best suits those who get after it everyday and every season whether they're climbing, skiing, or exploring the great outdoors even when things get wet.
