Didn't Gai also use them when he, Kakashi and Naruto were fighting Obito earlier in this fight?
Anyway, there's still plenty of time left for them to do it.
If Naruto hadn't given Team Gai cloaks this episode, you'd almost have forgotten they were even here.
Speaking of which, that was disappointing. I saw him give him those cloaks in the intro, and I thought maybe they'd use that power to bust out crazy awesome techniques they didn't have the power to use before. Instead, they just carried some Rasengans for Naruto.
