Snow camo is probably some of the most effective in the world. When you're in a snowy environment, it can be difficult to conceal yourself, until you grab a set of this stuff. If it's good enough for the Austrian Bundesheer, it's good enough for anyone in any snowy environment anywhere.
NOTE: These are used surplus items, so please allow for small tears, stains, and other minor imperfections. That being said, you won't receive a derelict set of crap that you can't use.
