Cnoc ThruBottle Review
The Ultimate Reusable Smartwater Bottle Replacement Just Got Lighter (V2 Upgrades!)
The Cnoc Outdoors ThruBottle is a durable, reusable water bottle designed specifically for thru-hikers and backpackers utilizing 28mm water filters. Think of it as everything you already love about using a classic Smartwater bottle as a filter vessel, the slim profile, the perfect side-pocket fit, and the seamless 28mm threading. However, reusing disposable Smartwater bottles long-term isn’t just bad for the environment; they aren’t safe for continuous reuse because the plastic degrades, leaches microplastics, and traps bacteria in the creases.
Cnoc recently dropped the ThruBottle 1000 V2, addressing the biggest critiques of the original version. The new model is significantly lighter, incredibly easy to squeeze, and manufactured right here in the US to lower its carbon footprint.
If you want to eliminate single-use plastic waste from your backcountry kit without altering your filtration workflow, this is the most practical sustainability swap you can make.
Cnoc ThruBottle vs. Smartwater Bottles: The Real Comparison
Most backpackers rely on disposable 1L Smartwater bottles paired with a Sawyer filter. While cheap and lightweight, they crack, crush, and require constant replacement. The original ThruBottle V1 solved the durability issue but introduced a noticeable weight penalty and a stiff body.
The ThruBottle 1000 V2 changes the game entirely. Here is how the specs stack up:
| Feature | Disposable 1L Smartwater | Cnoc ThruBottle V1 | Cnoc ThruBottle V2 (New) |
| Weight | ~36g–38g | 90g (83g without cord) | 63g (2.2 oz) |
| Squeezability | High (but creases/cracks) | Low (stiff hard-sided body) | High (re-engineered flexible body) |
| Durability | Low (Single-use plastic) | High | High (Long-term UV/rough use) |
| Origin | Mass-produced | Imported components | Made & Assembled in the USA |
| Measurement Lines | Printed (rubs off quickly) | Printed | Deeply Embossed (permanent) |
Size and Fit
The V2 retains the exact slim profile of the original and a standard 1L Smartwater bottle. It slides effortlessly into backpack side pockets, mesh exterior pockets, and shoulder strap water bottle sleeves without requiring any adjustments to your packing system.
Filter Compatibility
Featuring standard 28mm threading, the ThruBottle V2 connects flawlessly to your Sawyer filter setup and other popular backpacking water filters.
Weight Breakdown
For ultralight hikers counting every single gram, the original V1 weight was a tough sell. However, Cnoc shaved off 27 grams for V2, bringing the bottle down to a lean 63g. While it still carries a minor ~25g penalty over a flimsy, disposable gas station bottle, the massive jump in durability and structural integrity easily justifies the weight.
My Honest Cnoc ThruBottle Review
I’ve been using the original V1 ThruBottle for several months. By keeping it fresh with regular bottle cleaning tabs, it has held up really well. But it is hard to squeeze. Since it’s not that heavy, and still pretty new too, I’m going to keep using it as my clean water bottle.The V2 is 27g lighter (63g total) and way more squeezable, making it a true reusable Smartwater bottle replacement that makes pushing water through my Sawyer filter a lot easier on my hands. Carrying the V1 clean bottle adds about 25g over a standard Smartwater, but that isn’t going to break my back, and the combo works perfectly for my setup until I eventually pick up a second V2.
Temperature Note: The V2 is rated for operational temperatures from -58°F up to 175°F, and can handle liquids up to 212°F. Keep hot liquid exposure times short, however, to prevent material fatigue over time.
Pros and Cons
Pros
- Direct Smartwater Drop-in Replacement: Matches the exact size, 28mm threading, and pocket fit of standard disposable bottles.
- Incredibly Squeezable: V2 fixes the stiffness of the original, making filtration fast and easy on the wrists.
- Ultralight Upgrade: At 63g, it cuts 27g of weight from the previous iteration.
- Permanent Embossed Markings: Deeply stamped milliliter and ounce lines won’t rub off over time, making camp meal prep easy.
- Sustainable & Eco-Friendly: Shrunk carbon footprint via US assembly; curbside recyclable (just remove the nylon pull string).
- Smart Details: Updated tie loop and a high-visibility toggle make it incredibly easy to yank out of tight pack pockets.
Cons
- Still carries a minimal weight penalty: Weighs roughly 25g more than a fragile, single-use plastic bottle.
- No included sports cap: The bottle ships with a standard tethered cap. If you prefer a pull-top sports cap for on-the-fly drinking, you’ll need to purchase it separately.

Frequently Asked Questions about the Cnoc ThruBottle
Is the Cnoc ThruBottle compatible with the Sawyer Squeeze?
Yes. It uses the exact same 28mm universal thread size as standard disposable bottles, spinning directly onto the Sawyer Squeeze, Sawyer Mini, Sawyer Micro, LifeStraw Flex, and HydroBlu VersaFlow without leaking.
How much lighter is the ThruBottle V2 compared to the V1?
The V2 weighs 63 grams, making it 27 grams lighter than the original V1 model.
Can the ThruBottle handle boiling water?
Yes, it can temporarily handle liquids up to 212°F (100°C). However, the manufacturer recommends keeping exposure times brief to avoid material fatigue over time.
Does it come in different sizes?
Currently, the ThruBottle is available in a 1-liter capacity, but Cnoc has announced that 500ml and 700ml variations will be launching soon.
Can you buy the Cnoc ThruBottle in Canada?
Yes, Cnoc Outdoors and Amazon both ship the Cnoc ThruBottle directly to Canada
Should I upgrade to the V2 or buy the Cnoc ThruBottle V1 on sale?
It depends on your setup, but you can absolutely use both. Because clean water doesn’t need to be squeezed, the stiffer, original V1 makes a perfect, durable clean water bottle, especially if you can find it at a discounted closeout price. You can then pair it with the new ThruBottle V2 as your dirty water bottle, taking full advantage of its lighter weight and much more squeezable body where it matters most for filtration.
