Nalgene Splash Guards

Nina founds these Splash Guard inserts for wide mouth Nalgene bottles at EMS last weekend. I was at a church retreat a few months ago, when I caught a glimpse of someone's Nalgene bottle, it looked like there was a nifty insert that reduced the wide mouth to a more manageable size preventing water splashing all over her face. The best of both worlds, easy cleaning and easy drinking. I felt it might be rude to accost her about her bottle in the middle of a conference. Since I didn't get a good look at the insert and I couldn’t find it on the Nalgene website, I considered chalking it up as a figment of my overactive imagination. However, thanks to Nina, mystery solved.
