    • BeFree filter compatible

    Vesica is a reusable, lightweight water bottle that behaves much like a standard water bottle yet collapses down when empty for easy stashing. Vesica 42 mm has a wide-mouth screw-on cap, making it easier fill from shallow and low-flow water sources. The cap is tethered to the bottle so it can’t be lost. A cord loop near the top aids in pulling the bottle from a pack side pocket. And this slim bottle fits in many backpack strap bottle sleeves or bike water bottle cages.

    The bottle is soft in the middle, yet stiff in the neck and bottom. The tough TPU material is a little thicker than the Vecto Water Bladders. It’s easy to squeeze but stands on its own when full. And it’s much easier to squeeze than Smartwater bottles. When full, with the cap off, you do have to be careful of accidentally squeezing water out while gripping the bottle, so we recommend holding it from the top. The stiff top and bottom make it easier to pull from pack side pockets and put back in. TPU is FDA approved and BPA free.


    Filter Compatibility

    Manufacturer Model 28 mm Narrow Mouth 42 mm Wide Mouth 
       Sawyer Squeeze

    Vesica 42 mm is compatible only with the popular BeFree water filter by Katadyn (not compatible with Sawyer filters). Just fill the bottle with dirty water, screw on the filter, squeeze the bottle, and drink clean water right from the filter. Or filter into another bottle for drinking. Unlike a Smartwater bottle, you can squeeze all the water out without having to stop to unscrew the filter to allow more air into the bottle. With Vesica, just keep squeezing. That’s its superpower. You can also set up a BeFree gravity feed filter using a Vecto/Vesica 42 mm for dirty water and a Vesica 28 mm for clean. Screw a Coupling to the BeFree to attach the 28 mm bottle.

    So stop using disposable water bottles and take a reusable, lightweight Vesica water bottle instead. TPU is safer for drinking than PET, which can degrade with reuse and potentially leach into the water. You may just find this becomes your favorite EDC water bottle to stay hydrated. And it takes ice cubes too.

    1. A solid collapsible bottle  star rating

      Posted by Unknown on 3rd Jun 2023

      No leaking. Feels solid, if that's not an oxymoron. I bought this to replace my well-used Platypus collapsible, and I like the softness of this bottle's material better.

      Also, I was having some trouble getting the order to go through, and Litesmith was terrific at helping me. Prompt and effective.
