I get a kick out of how Sarbar says that - expecting someone to poke fun at her. LOL Now we get to continually remind you of the 5oz of savings that you are missing out on. Yes, nalgenes weigh more, but if you prefer them - then go for it. HYOH... and I mean it.

I always premeasure known liquids at home, then make marks on containers - like other have said. I generally use my SnowPeak mug that has stamped marks in the cup... easy!

Someone please use the term "meniscus" in their response.
