Here's a pic from an Amazon page.
$36.30 I think the color is brown, but it looks sort'a purple on my screen. Mine is a dark green.
They will separate and can be used as 2 individual backpacks. They are quite large.
I think they're a good deal for the price but of course, they aren't like the $300-400 fancy ones.
I think they are available in brown, green, blue, and maybe a bright safety orange.
