Throughout all my testing the Beta SL proved to be highly waterproof and kept me dry during some wet and windy days in the hills. I really appreciated the big adjustable StormHood which helped keep the rain and wind off my face. Arc’teryx markets the hood as helmet compatible and while I didn’t get a chance to test it while out climbing, I did try a helmet on in the house and can confirm it fits well.
I can see myself using the Beta SL a lot due to it being highly waterproof but also being lightweight with the ability to pack down small. A technique I use for a lot of my waterproofs is to roll them up into their hood and use the hood adjustments to cinch it down into a nice compact package. When this is done with the Beta SL, the jacket becomes a really compact package that doesn’t take up much space in your bag, which is a big pro for me.
While waterproof jackets are not really known for their breathability the Beta SL did a decent job due to its lighter construction and pit zips which really help with airflow. Despite this jacket being on the lighter side, it does still feel durable and I would have confidence in its resistance to abrasion.
While RECCO isn’t something I’d pick a jacket specifically for, it’s a nice thing to have. If I get lost in the mountains it’s nice to know it could help me be found.
