Learn how to fill, carry, and care for the Vecto 3L water container. Get practical steps for using the dual-opening system and keeping it clean on the trail.
Quick answer
The Vecto 3L water container works best when you use its wide opening for filling from streams or taps, then close it and carry it using the narrow 28mm mouthpiece for drinking or attaching a filter. Clean it by rinsing with warm water and mild soap after each trip, and dry it fully before storage to prevent mold. Always check the threading for a secure seal before you rely on it.
Filling your Vecto without the mess
Start by locating the wide opening—it's the side with the larger cap. Unscrew it and scoop or pour water directly from a source. Because the Vecto is soft and collapsible, you can squeeze the body to create a funnel shape that makes filling from shallow pools easier. Once filled, screw the wide cap back on tightly. The narrow 28mm mouthpiece stays closed during this step, so you don't have to worry about spills from the drinking side.
A common mistake is overfilling the container. Leave a small air gap so the Vecto can flex when you squeeze it or when it's compressed in your pack. Overfilling can stress the seams over time. Also, avoid filling from sources with heavy sediment; if you must, let the water settle and decant it before drinking.
Carrying and using the Vecto on the trail
The Vecto 3L weighs just 2.9 oz (84 g) and collapses to a small bundle when empty, so it's easy to stash in a side pocket or pack lid. When full, it fits in most backpack side pockets, but because it's soft, it may bulge. For a balanced carry, place it in the center of your pack or use a hydration sleeve if your pack has one. The narrow 28mm opening is compatible with many standard water filters and hoses, so you can drink directly or set up a gravity system.
If you're using the Vecto with a gravity filter, hang it from a tree or trekking pole using the handle or a loop of cord. The wide opening makes it simple to fill from a stream without removing your pack. Just remember to close both caps before you hang it—gravity will find any loose threads. For drinking on the go, the narrow mouthpiece is easy to open and close, even with one hand.
Cleaning and storing your Vecto
After each trip, empty any remaining water and rinse the Vecto with warm water and a few drops of mild dish soap. Use a soft bottle brush to scrub the inside, especially around the threads and the narrow mouthpiece. Avoid harsh chemicals or bleach, which can degrade the TPU material over time. Rinse thoroughly until no soapy taste remains.
To dry, open both caps and hang the Vecto upside down in a well-ventilated area away from direct sunlight. Make sure the interior is completely dry before you store it; trapped moisture can lead to mold or a musty smell. Once dry, store it loosely folded in a cool, dark place. Don't compress it tightly or leave it in a hot car—heat can weaken the material.
Step-by-step: Using and caring for your Vecto
- Fill from the wide opening: Unscrew the large cap and scoop or pour water in. Squeeze the Vecto to create a funnel if the source is shallow. Checkpoint: Don't overfill—leave a small air gap so the container can flex.
- Close both caps securely: Tighten the wide cap and make sure the narrow 28mm mouthpiece is closed before carrying or hanging. Checkpoint: A loose cap will leak in your pack; test by squeezing gently over a sink.
- Carry it comfortably: Place the filled Vecto in a side pocket or centered in your pack. Use the handle to hang it for gravity filtering. Checkpoint: If your pack feels unbalanced, move the Vecto closer to your back.
- Drink or filter from the narrow opening: The 28mm threads fit many standard filters and hoses. Open the mouthpiece to drink directly or attach a filter. Checkpoint: After attaching a filter, test the connection for leaks before you rely on it.
- Clean after every trip: Rinse with warm water and mild soap, scrub the inside and threads with a soft brush, then rinse thoroughly. Checkpoint: Avoid bleach or harsh chemicals that can damage the TPU material.
- Dry and store properly: Hang upside down with both caps open until completely dry. Store folded loosely in a cool, dark place. Checkpoint: Never store damp—mold will ruin the taste and may be unsafe.
