I just watched the movie Guardians of the Galaxy: Vol. 2 last night. The end of the movie is a bit hazy so maybe there is some detail that I don't remember.
In the first movie, they showed that Peter can use his suit in the vacuum of space and survive. He used it to exit the prison and again to save Gamora at Knowhere.
I'm wondering why Peter couldn't use his suit/mask at the end of the 2nd movie
instead of Yondu giving him the only space suit left.
