Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


A simple system for getting clean water. Simply drop the intake hose into your water source, squeeze the handle, and drink. The TrailShot Filter lets you drink straight from the water source, but you also have the option to fill bottles by simply squeezing the handle to pump water.

  • Water quality will significantly affect the filter's life
  • Mouthpiece has a debris cover to keep things clean
