That's not quite accurate. The 32oz Gatorade bottle's max diameter is a bit larger than that of the 1L Nalgene. So cups like the popular GSI Outdoors Glacier Cup fit very closely to the Nalgene but won't accept the Gatorade bottle.

That's one of the reasons I like the 750-800ml Toaks pots so much, they offer a very close no-rattle fit to the Gatorade bottle. The Snow Peak Trek 700 accepts both the Gatorade and the Nalgene but it is a sloppy fit with wasted space.
