"The mysterious engineering problem causing F-22 Raptor pilots to choke in their cockpits has been solved, the Pentagon says. And it’s not the nearly $400 million aircraft’s fault after all.
The problem lies with a valve in the pressurized vest pilots wear as they fly the jet at high altitudes, Pentagon spokesman George Little said. The valve inflated the vest, limiting the pilots’ oxygen supply. It does not appear that the vest was affecting quality of the oxygen in the Raptor. The valve will be replaced; the garment’s use will be “suspended,” Little said.
Additionally, the Air Force has decided to remove a filter it placed in the jet to test the oxygen quality. Ironically, the filter ended up limiting the oxygen supply to the pilots. But the charcoal filter resulted in “no oxygen contamination,” Little told reporters at the Pentagon on Tuesday."

(commentary)
I'm calling shenanigans on allegations that the vests were the root of the problem. These vests are likely worn in other aircraft without fault. If the choking problem is indeed fixed, it's likely due to the additional oxygen filter which is being replaced.

Aviation Pilot Supplies is the basic thing which pilot should have all the time. Thanks for this such a great informative blog.
