The Black Rock Hat is made with ultralight ripstop fabric, 900 fill canadian white goose down, and lined with soft wicking dryline so it molds to your head and stays comfortably in place. This is the hat if weight and warmth matter. It weighs less than one ounce and compresses small enough to fit in a pocket so you can take it anywhere.
The hat is well made with clean stitching and no lose threads. The hat is very light – .9 ounces. This is an 1-½ ounces less than the lightest weight fleece hat. It balls up to just a bit larger that a golf ball, so it takes up almost no space. The hat could be just a little longer, as it did tends to ride up a little with movement.
