CNOC VectoX 3L Review

Overview

The VectoX is CNOC Outdoors’ reinforced take on the Vecto, the wide-mouth collapsible water bag that’s become the default “dirty bag” for Sawyer Squeeze users on the PCT, CDT, and just about every other long trail. It’s built for hikers who want to scoop water fast from a shallow source, filter it without fuss, and pack the whole system down to almost nothing when it’s empty. If you’ve been nursing pinhole leaks in an original Vecto, the VectoX is the fix CNOC built specifically for you.

Performance

The core design hasn’t changed from the original Vecto, and that’s a good thing — it’s still the easiest bag on the market to fill from an ankle-deep puddle or a trickling seep. The dual-opening design gives you a slider-sealed wide opening plus a standard soda bottle-style screw neck, so you scoop water in through the wide top, then thread a Sawyer or similar filter onto the 28mm neck and squeeze or hang it as a gravity feed. The slider mechanism itself is a nice touch over older designs — it’s much easier to open and close using the bottom slider when scooping from a flowing stream compared to older, stiffer versions.

Where the VectoX earns its name and its extra few grams is durability. The X refers to “eXtra durability” — it’s built with a thicker TPU body for an additional half ounce of weight, which increases puncture and abrasion resistance. That matters because the standard Vecto has a real, documented failure mode: one long-term reviewer found the Vecto pretty durable through heavy use, but had two of them develop a tiny pinprick hole that only leaked under pressure, though the bag remained usable for the rest of the trip. CNOC’s response was the VectoX, and the thicker, tougher material seems to be a direct answer to that pinhole leak problem. CleverHiker’s testing backs up the durability claim on paper: CNOC claims the Vecto has a breaking point of 220 pounds, while the VectoX withstands up to 450 pounds, and in their testing they hadn’t noticed any leaks. That said, this is still a young product relative to the original Vecto’s track record, so long-term pinhole resistance over a full thru-hike season is more promising than proven at this point.

On weight and packability, the VectoX gives up very little for the durability gain. CleverHiker measured it at 3.32 ounces, the third lightest bladder they tested, only behind the Hydrapak Seeker and the Platypus Platy, with the regular Vecto shaving off a bit more weight at 2.8 ounces for the two-liter size. Packed down, they measured it at 6.5 by 2.25 by 1.5 inches, second only to the Platypus Platy for packability — plenty small enough to stuff into a hip belt pocket or the bottom of your food bag. The one minor ding on the design: the plastic slider makes it somewhat bulkier than some competing ultralight bladders, though it significantly improves ease of cleaning, which is a trade-off I’ll happily take given how much I hate trying to scrub mold out of a narrow-necked bladder at 2 a.m.

Taste and heat tolerance round out the practical picture. CleverHiker also noted water from the VectoX tasted better than many of the other hydration bladders they tested, which lines up with the general reputation TPU has over PVC or vinyl bladders for not imparting a plastic taste. It’s also rated to handle boiling water, though CNOC itself is cautious here: while the container can technically hold liquid up to 212°F, they recommend staying at or below 176°F to avoid burns and material fatigue. Worth remembering if you’re using it to store hot water for a Nalgene-bottle sleeping-bag warmer trick.

One thing to know before you buy: TPU is a porous material, so the bag isn’t completely odor-free right out of the box. A rinse or two with diluted vinegar or baking soda before first use takes care of it, but don’t be alarmed if it smells a bit “new” on arrival.

Pros & Cons

Pros:

• Meaningfully more puncture- and abrasion-resistant than the standard Vecto, addressing a known complaint
• Among the lightest and most packable bladders on the market despite the reinforcement
• Wide-mouth slider makes scooping from shallow sources fast and easy
• Dual 28mm/screw-neck opening plays nicely with Sawyer filters and most other 28mm threads
• Wide opening makes cleaning and drying far easier than narrow-neck bladders
• Can handle near-boiling water if needed

Cons:

• No hose or bite valve — this is a storage/filtering bag, not a sipping reservoir
• Slider adds a bit of bulk versus simpler bladder designs
• Slightly heavier and pricier than the standard Vecto, though for most people that trade-off is worth it
• Fresh-out-of-the-package TPU smell that needs a rinse or two before use

Who Should Buy This

This is the right call for thru-hikers and backpackers running a Sawyer Squeeze (or similar 28mm filter) gravity or squeeze setup who’ve either had durability issues with the original Vecto or simply want peace of mind before committing to a multi-month trail. It’s also a smart pick for anyone doing dry camping who needs to haul several liters over a mile or more of trail without worrying about a pinhole leak soaking their pack. If you just want a sip-while-you-walk hydration bladder for day hikes, look elsewhere — this bag has no hose.

Verdict

The VectoX takes an already-excellent water storage system and fixes its one real weakness — durability — for a trivial weight penalty. It’s not flashy, but it does exactly what it’s supposed to do, and does it a little more reliably than its predecessor. I’d rate it an 8.5/10 and consider it the default choice over the standard Vecto for anyone heading out on a trip longer than a weekend.
