As much as I love Backcountry.com, the pictures are not always dead on! It's happened to me a few times form them that I have got a siff color then what it was or looked like. Or key details missing like the PURPLE liner of the SB Utility jacket in Black. This looked "tan" on the pictures!
I would trust Sierra's picture more. Just Google it to death or check the manufacturers site if it's still up!
