For sale is a set of the U.S. Air Force fighter pilot helmet HGU-68P and high-G oxygen mask MBU-20P. These are new and imported from the U.S. Of course, I have not worn them. I only opened the top and zipper of the bag upon delivery, then stored them in the box. I'm the type who is satisfied with the purchase itself. The helmet color is matte brown. The size is large. The helmet bag and clear visor are also included. How about it, aviation enthusiasts? By the way, there is currently only one listed on Sekaimon. The final total payment was 499,413 yen, and that was without the high-G oxygen mask. Due to recent reports of returns and other issues, I would like to decline returns or complaints. The last photo is of a current Japan Air Self-Defense Force helmet. Although the color is different, don't you think they look similar? I bought this thinking it was a similar helmet after researching it. Thank you.
