The Sovereign Bottle

64 oz

Half-gallon. Full day of hydration in one fill. Collapsed flat fits in a jacket pocket.

120 oz

The expedition size. Hike, travel, long shifts. One fill lasts the entire day at high output.

Flatter Than Anything Out There

Collapsible bottles have been around a while — but they still look and feel bulky. The Sovereign Bottle collapses to under 1cm and looks completely smooth doing it. No ridges showing. No puffy rings. Just flat.

Invisible Collapse — No Bulky Look

The old collapsibles looked like the pants from Back to the Future — that puffy accordion aesthetic nobody asked for. The Sovereign Bottle's fold geometry is built into the wall material itself, invisible from the outside. Full, it looks like a normal bottle. Flat, it looks like a disc.

Three Collapse Styles

Smooth flat — no visible seam, the wall just disappears. Zipper-edge flat — a single clean fold line down one side, like a sealed pouch. Structured flat — rigid disc with walls recessed flush. You choose the look.

Rigid-Base Architecture

The base disc is solid — polished stainless or carbon composite. It never collapses. The walls fold down flush around it. Flat, it's a stable disc you can set on a table or clip to a bag without it flopping around.

Sovereign Seal Cap

Leak-proof twist-lock cap with integrated carry loop. When collapsed, the cap locks the flat stack closed — a rigid puck, not a floppy bag. Cap and base match diameter when flat.

Built for the Sovereign Kit

Collapses flat into the jumpsuit's interior pocket. On a ride, at a game, traveling — you don't leave it behind because it takes zero space empty. Full kit: helmet, suit, bottle.
