I may not have the quote quite right, but I think it was Churchill who said the Bjorn is the worst baby carrier we have, except for all the rest.
If you're wedded to the Bjorn, but you have real issues with the original, solid navy blue fabric, check out Baby Bella Maya's "Designer Front Pack Covers."
BBM makes fitted fabric slipcovers for most front-worn carriers, including the Bjorn and the Snugli. Most of the fabrics are a total chickfest, with satiny brocades and floral prints. But there's also one token cover for dads--and of course, it's camo. If you want a solid fabric, all you have to do is reverse the BBM cover. Or take it off.
