In Avengers: Infinity War, Spider-Man gets a new suit from Iron Man during their way up to space. The suit was also seen in the ending of Spider-Man: Homecoming.
Iron Man used a nano tech suit in the movie. Is the suit given to Spider-Man also nano tech? Is there any reference to this?
It's not explicity stated but the indications are that it is.
We see the suit arrive (by jetpack) and as it deploys on Spider-man it does so by flowing across his body as does the Iron Man armour for Stark.
In addition, the Spider-armour deploys legs, effectively from nowhere (certainly there is no space on Spider-Man's back for them to be stored) a further indication that the armor is nano-tech.
