You can also use football wide receiver gloves, but be warned that for this community they may be a bit extreme -- no padding in the palm, very thin leather, and extremely sticky (made to grab and hold a football as you run with it -- get it?). They're superb for racing, but not necessarily for any other riding. There was a thread on them recently on FixedGearFever.com, which everyone on this forum might check on -- very nicely done albeit race oriented.
On the Tanabes there are a whole array of keirin gloves available: some thin simple white ones (look like golfing gloves), some very nice black ones with soft kevlar reinforced knuckle pads (my personal favorite, and the choice of the French national team), the ones with the hard kevlar knuckle covers (they make BMX gloves look tame; you can get them in red/white and red/black, but they look pretty extreme and are a bit overkill), the ones with the hard kevlar knuckle covers plus air vents in the kevlar (extremely wicked looking, but you start feeling stupid for wearing them), and then the heavily padded white ones (which were what Pearl Izumi imitated). They all are in the $110-125 a pair range and generally last well in racing but won't do well with continuous road fixed gear use.
