CNOC ThruBottle 1l

CNOC ThruBottle 1l - the perfect Smartwater bottle replacement.

ThruBottle 1l is the game-changing reusable water bottle that ultralight hikers and thru-hikers have been waiting for. After years of relying on disposable Smartwater bottles, there's finally a durable, reusable alternative that doesn't sacrifice the slim profile and filter compatibility that made Smartwater the trail favorite.

The ThruBottle is the result of multiple years of design, testing, and refinement by CNOC Outdoors, a B-Corp certified company known for their innovative hydration solutions. This patent-pending, one-liter bottle delivers the lightweight performance ultralight backpackers demand, with the durability and safety features needed for long-distance hiking.

The Problem with Disposable Bottles

For years, ultralight hikers have relied on disposable Smartwater bottles because they're cheap, light, and work perfectly with squeeze filters. But there's a catch: they're single-use plastics being repurposed for long-term use, they bend and crinkle over time after repeated squeezing, and get covered in creases and dents after just weeks on trail. Plus, concerns about microplastic shedding and environmental impact have made many hikers uncomfortable with this system.

The ThruBottle Solution

CNOC designed the ThruBottle to keep everything hikers love about the Smartwater system while addressing its shortcomings. You get the same slim profile, the same 28mm filter compatibility, and the same pack-friendly design - but in a durable HDPE plastic that doesn't bend and crinkle over time and essentially looks brand new even after a month of hard use.
