I guess it all depends on why and how you're carrying it. Certainly it's not an EDC or something you'd put in your pocket, however it's not any larger than a 2D Maglite and I don't think that's an unreasonable form factor.
It's a large and heavy flashlight that's less convenient than a pocket light so with something that size and that powerful I was just curious what people use it for and how they'd normally travel with it. It doesn't look like a light I'd go walking with because it's bulky and heavy. I wouldn't likely carry around a 2D Maglite either but maybe you or other's do.
