Five colors

Five colors. Three of them limited to 1,000.

Night and Ocean have 2,000 bottles each. Pale, Moss and Lava are limited to 1,000 pieces each, and there is no second run before spring. Waitlist members pick their color 24 hours before everyone else.

Designed end to end

"We build products people reach for without thinking. That means the lid has to open one-handed, the lock has to hold in a full bag, and the finish has to survive years of use."

Off-the-shelf bottles get you close. They never get you all the way, because nobody drew them around the way our customers actually use them. So for the Signature we started with a blank sheet and drew every part ourselves: the lid, the lock, the handle, the shape, the finish.

The result is a bottle only we can offer, and every detail in it has a reason.
