Fett and Djarin basically don the same Mandalorian armor, with the only differences being the color of the armor and a few other subtle differences.
The only major difference between the two characters’ armor was that Fett’s included a jetpack from the jump and Djarin didn’t get one until the The Mandalorian Season 1 finale.
Look past those differences and you’re left with essentially the same type of armor.
Now that this little difference was fixed, the two look even more similar than they did before.
