+7 pts“Used the mt900 (on trekking poles) hospital white tent, you could see it even in the darkest night, not to mention the interior which didn't require any headlamp at all, too bright for me. I'd go for some green/brown, even gray probably because I like how it blends in while not being too bright inside through a full moon night above the treeline and for the ability to keep it cleanish easier. Those being said, if I get a 15%+ discount, sign me up for the weirdest color that you have on stock.”
