Purist
Keeper 14oz
Our most premium bottle yet.
Crafted with a solid stainless‑steel handle and open, sculpted ergonomics, it rests naturally in your hand. The open handle is shaped to encourage control, intention, and ease—principles familiar to those who value balance in every movement. Seamless welding creates a smooth, uninterrupted form that feels as refined as it looks.
Limited colorways.

Purist Technology
Our bottle lining is made entirely from silicon dioxide—the same naturally occurring compound found in quartz and in the amorphous form we know as glass.
Unlike traditional glass, which blends silicon dioxide with additional materials, our lining uses only the pure material. The result is a smooth, hydrophobic surface that resists flavor transfer and preserves what’s inside.
Applied in an ultra‑thin layer, the lining delivers a durable, shatter‑resistant interior — ensuring every sip tastes clean and true, free from stainless‑steel interference.
The result is a bottle that tastes as pure as drinking from glass, paired with the insulation, strength, and sustainability of stainless steel. The best of both worlds.
