I ended up ordering the Houdini in the new Brown. Not bad and kinda matches the brown of my Granite Gear Blaze A.C. 60. I also ordered the "Paintbrush Red" to compare...but good lord is that a bright red. Borderline neon.
I'm very happy with the design on the Houdini. The hood can be made to essentially lock onto your head and I really appreciate the cinch-able bottom/back. At 5'9"ish 130lbs., the size small I felt fit me the best. I'm pretty much between a small or medium.
I actually chose the small because I could still squeeze my Marmot Zeus (S) jacket under it without smooshing the down (though the Zeus actually has a bigger torso diameter than the Houdini in Small). The Medium fit better over the Zeus jacket, but left more of a gap under my chin with the hood up and also left "wing outs" of the hood at my ears. Additionally, the cinch at the bottom of the jacket required a LOT of cord to be pulled to get it tight.
It kinda dawned on my that should I be in a weather situation where I would be wearing the Zeus jacket...it's probably too cold for skeeters. So, I sided on the Small for it's tighter fit to better keep me protected from the wind and skeeters due to the tighter fit...also less loose jacket to flap in the wind.
For those that are wondering, the size Small Houdini weighed in at exactly 3.5oz.
