^ Because in B&R, it was so obvious that the only reason for Batman, Robin and Batgirl to take time out from going to fight Freeze and change outfits was so that the studio could sell more action figures. 'Batman - snow suit'. 'Robin - snow suit.' 'Batgirl - snow suit.'
This isn't at all comparable to Bale's Batman and Lucius Fox discussing quite logical upgrades to his outfit; especially in a series which has spend some time trying to show how Batman and his technology would work in the real world.
