Harrumph! I'm 6'1", Vibrantly Masculine, and found it perfect. One bag full of 30 rd SLR mags slung under left armpit, one bag full of WP hand grenades under right, shell dressings taped to straps, bayonet between teeth, proceed! Young people these days, I don't know...(wanders off, shaking head ruefully and muttering to self)
Always used to be the claymore bag or an old WW2 respirator bag. Nowadays though seems that they are as much a fashion accessory as a practical item.
BoB's are big business in the USA. After the flooding they had in New Orleans a few of the States have actively started encouraging residents in flood and hurricane prone locations to put together BoB's. Therefore bag manufacturers have started making 'Special BoBs' and this has. I think, spilled into the military when you see companies that used to make civvy gear suddenly offering exactly the same bags in Coyote tan and ACU pattern.
