  • Snaps inside neck of wide-mouth Nalgenes
  • Slows the flow of water
  • Controls unexpected splashes and spills on the go
  • Easier pouring
  • 60% lighter than silicone splash guards


When drinking on the go (walking or in a car), wide-mouth Nalgenes sometimes surprise you by splashing water all over your face and often soaking your shirt. The Easy Sipper snaps securely inside the neck of a wide-mouth Nalgene to slow the flow of water and help curb unexpected splashes and spills for more controlled drinking. It's stiffer, lighter, simple to install, and won't easily push through like some of the flexible silicone splash guards. And it's easy to pop out to add water or ice and for regular cleaning. As an added bonus, the smaller hole makes pouring easier into a cooking pot or cup.

Easy Sipper fits ONLY 32 oz (1 L) and 48 oz (1.4 L) wide-mouth Nalgenes. Will NOT fit 16 oz (0.5 L) or any narrow-mouth Nalgenes.
