Arc'teryx Beta LT vs Rab Kinetic 2.0

However, if you care about every ounce and packability, go for something with down. I like the Uniqlo packable down hoody. It's a few ounces lighter than the Arc'teryx and packs down smaller.

But for $500, it’s definitely a souped-up option: The design is decidedly fashionable (as we’ve come to expect from Sweden-based Fjallraven), considerably more durable with a 60-denier polyester fabric, and heavier at 1 pound 0.6 ounces. Notably, the Eco-Shell also proved to be a lot more waterproof throughout our testing (Fjallraven gives it a 30K waterproof rating, which towers over the Rab's 10K rating). In the end, the lightweight and streamlined Rab is a better option for weight-conscious alpine climbers looking for a decently waterproof hybrid, but we’re big fans of the Fjallraven for shoulder-season hiking, skiing, and around-town use
