I've got the Schwinn version of a fanny pack that I've got on the front of my mtb, but it's heavy. It does carry all my fix-it tools, though, plus my phone, keys, First Aid kit, and tissues (my nose runs a lot while riding). D*H thinks it's pretty ridiculous, and I agree with him, so I just ordered a seat bag and a bento box from TE here.

Somehow carrying all the same stuff in two smaller bags makes more sense than the one big bag on the front of my handlebars. Go figure.
