CNOC 1L ThruBottle HDPE

CNOC ThruBottle 1L

A purpose-built, reusable 1-liter bottle designed specifically for long-distance hiking and thru-hiking where durability, safety through extended sun exposure, and direct filter compatibility all matter more than saving a few grams with a disposable smartwater bottle. The ThruBottle is the result of years of design and testing for ultralight backpackers who want a bottle built to last a full trail season.

Why We Carry It
It's the bottle we recommend for thru-hikers who want a dedicated, reusable squeeze filter bottle that holds up through months of hard use rather than replacing disposable bottles every few weeks.

Highlights

• Purpose-built for long-term thru-hike use — Designed and tested specifically for the demands of extended hiking including prolonged sun exposure, rough handling, and repeated filter attachment and detachment over thousands of miles. A meaningful durability upgrade over repurposed disposable bottles.
• 28mm thread for direct filter attachment — Connects directly to Sawyer Squeeze, Mini, Micro, LifeStraw Flex, and HydroBlu Versa Flow filters without adapters. Fill, attach, squeeze, and drink without an intermediate vessel.
• BPA, BPS, and BPF free HDPE construction — Clean material standard free of common plastic additives across all three bisphenol variants. Safe for long-term water contact through an entire hiking season without chemical taste or material degradation concerns.
• Slim profile that fits backpack side pockets — A narrow 2.9-inch diameter designed to slide cleanly into standard backpack side pockets without forcing or leaving the bottle partially exposed. A practical dimension that shows up every time you reach for water on the move.
• Nylon pull string near the cap — Makes retrieving the bottle from a side pocket easy with one hand without stopping or removing your pack. A small detail that adds up over thousands of side pocket access points on a long trail.
• Ounce and milliliter measurement lines — Track water intake and monitor consumption on waterless stretches without a separate measuring vessel.
• Tethered cap — Stays attached to the bottle so you never lose the cap at a water source or in a dark camp shelter.
• Wide operational temperature range from -18°F to 175°F — Handles cold weather camping and can hold boiled liquids for hot drinks and food preparation at camp. Use below 176°F to avoid material fatigue and burn risk.
• Assembled in USA — Domestic assembly from domestic and global components.

Best for

Thru-hikers and ultralight backpackers who want a dedicated, reusable filter bottle built to last a full trail season with direct 28mm filter thread compatibility and a slim profile that works with standard pack side pockets. A strong upgrade from disposable smartwater bottles for anyone committed to a long trail who wants a bottle purpose-built for the job.

Compatibility Note

28mm thread fits Sawyer Squeeze, Mini, Micro, LifeStraw Flex, and HydroBlu Versa Flow filters. Can hold boiled liquids but recommended maximum temperature is 176°F to avoid burns and material fatigue.
