Review on Nalgene Easy Sipper - Designed Specifically For Your NALGENE 32 Oz Wide Mouth Bottle by Bryan Aleman

I got this product to replace the humangear capcap gen 2 I ordered a couple of years ago. I didn't like how the silicone o-ring design would often house mildew.This definitely fit the bill.Clocking at about $6 if you choose a not-bulk pack this insert is snug enough in the wide mouth. Fit was my main concern as i was concerned that if I attempted a "Chug" the water might cascade through attachment, dislodging it thoroughly and pour the contents of my 32 oz Nalgene on my lower face and chest.There is not fitment issues. It sits snugly in the mouth, and cannot be easily removed unless you stick your finger into the hole and pull out with some intention, at which point it will "pop" out with some authority.The texture of the attachment is a matte. I have rinsed it, but if it required committed cleaning, it will surely be easy to do.See attached photos for detail.The attachment will fit in the 48 oz widemouth nalgene as well. Second photo from a oblique angle shows 48 oz.Also, Pink!
