In excellent condition No signs of wear, like new Bomber waterproof jacket Arc’teryx’s Beta SL Hybrid isn’t your typical rain shell. As its name suggests, the hybrid construction blends two Gore-Tex fabrics of different thicknesses to maximize weatherproofing, minimize weight, and boost durability in wear-prone areas. Using both 2-layer Gore-Tex with Paclite Plus and 3-layer Gore-Tex with C-Knit, the Arc’teryx Beta SL Hybrid is a formidable barrier against the elements. The 3-layer Gore-Tex on the front and shoulders is designed to boost protection in critical areas: when hiking or biking, and particularly with a pack, the front of the body and shoulders tend to take the brunt of the precipitation and wind. Using 2-layer Gore-Tex on the rest of the design allowed Arc’teryx to shave ounces without sacrificing wet-weather performance. I’ve worn the Beta SL Hybrid in torrential rainstorms and it has shown no signs of leaking or wetting out. I’ve also thrown it on while traversing windy mountain passes and it has done an admirable job at sealing out strong gusts. I haven’t yet gotten to test the Beta SL Hybrid in rough winter conditions, but I’m confident enough in its performance thus far to throw it in my backcountry ski pack this coming season.
