Ed P.wrote a review of Arc'teryx Hyllus Hooded Fleece Jacket - Men's on December 14, 2011
The pictures online make it hard to tell about the build of this jacket. There is no storm flap and the powershield O2 seems pretty weak, this is very much a layering piece, and not that warm without a shell to go on top. Go look at this in a store before you buy it. I found the seams and other minor quality details a bit sub-par for the Arc'teryx price. Doesn't seem to make a lot of sense to me to buy this jacket, go get a windproof fleece which is really all this is. The Hyllus is only really great for mild to cool weather or being highly active in cold temps with low wind. For a super warm winter softshell for bumming around town and belay-bitching in the frigid mornings try the Firee, that jacket is bomber. If you want a sick alpine softshell that's not gonna sweat out look at the Venta instead of the Hyllus. No room for the Hyllus on my coat rack - there are better options out there.
