Are the bottle holders large enough to fit Nalgene brand bottles?
RAPHAEL K To answer your question, I don't own the Nalgene water bottles you're talking about, but if you mean the 32 oz. bottles, then NO, it won't fit. The pouch is so snug that it can only fit standard size bottles like the ones you put on the water bottle rack of your bicycle. Hope this helps.
TRAVIS N I have this pack and would say anything larger than 0.5 L (~16 oz) would not fit well. I don't believe the 1 L Nalgenes would fit; however, I did not try one. Hope this helps.
