They discontinued it. It was my favorite as well. Should have stocked up when i had the chance. It was also nylon instead of polyester which resists stink quite a but more and is more comfortable to sleep inBlack Diamond AlpenGlow Pro is the best sun hoody I've tried (and have a bunch of them). The mesh armpits makes a significant differance. You have to get the Pro model to get that feature.
I haven't tried Kuiu's Tiburon sun hoody yet, but it looks promising.
