Is this any warmer than the Hyllus?

Polartec's website says that Powershield O2 blocks 96% of wind (that's the Hercules and his son, Hyllus) and Powershield blocks 98% of wind (this jacket) Neither are waterproof. Powershield Pro is a third textile, which might be waterproof, but, at this point in time, Arc'teryx is not usimg. I'm sure they will soon, though.

BCizzle, I've used both, and the Firee isn't waterproof (super resistant, not a rain jacket), nor the Hyllus windproof (but it blocks most of it up to about 40mph gusts). I will say I wear my Hyllus more than any other jacket I own.

Hey Brandon, According to the information listed, the Firee is constructed with Polartec Power Shield and when bouncing that information off Polartec's website that fabric is supposed to be waterproof - wouldn't that make this hoody windproof? Also, according to information the Hyllus is composed of Polartec Power Shield O2, taking a look at that part of Polartec's website the O2 is supposed to be 96% windproof. Where's the disconnect? Thanks for any info as I'm looking at the Hyllus myself.

The new Arc'teryx Firee is more weather resistant than the Hyllus (Firee blocks 90% of wind, Hyllus 50%) and designed to be worn as a very weather resistant, super breathable outer layer, while the Hyllus is cut more trim to do double duty: outer, and layered. Insulation wise, they both use the same high-loft fleece inside.
