There are many long-trousered meshes for males, fat, fit and skinny; and most of them don't have ankles.
BAK1 is the male equivalent of B002FAFit. The standard B002 meshes were done in a disorganized way: the three male versions have no ankles, neither does the fat female, the fit female has narrow-legged jeans showing ankles, Maxis hasn't included a skinny female version (but a fan-made version is available from Jack Wolfsim) and the child version has wider trouser legs, but still shows ankles. The BAK1 meshes, made by combining the male B002 meshes with B005MAFit (the closest thing to B002FAFit in trouser shape), were used to make the male BAG1 "flares" meshes, and can take BAG1MA textures. They're nothing special by themselves, but can be useful as bases for other meshes.
Update 10-12-2006/12-01-2007: after letting them sit for two years, I
finally removed the 50+ duplicate vertices from the feet, legs and arms.
The mesh shapes haven't changed, but the files are slightly smaller now.
Update 15-07-2007: well well, the Mac crashes over the Unix linefeeds
left by the undoubling. Better correct that.
Update 12-04-2008: Fixed some UV niggles. Added MABBS, MCSMA mesh.
