Why it's on the list
The wide-mouth bottle is the water you drink from. This is the cup you carry between camps: coffee in the morning, a cold drink in the shade, something in your hand on the bike that does not become a splash. A stainless mug, insulated, with a lid that actually seals and a handle you can hook on a finger. Sixteen to twenty ounces is the size people still have at the next art piece. A beautiful open cup left on a table is the same as no cup.
How we use it
Write your name on the bottom. Dust in the slider is how it stops closing, so rinse the lid. A carabiner through the handle keeps it on the basket. If the listing is a lidless enamel camp mug, it is the kitchen, not the day bag.
Heads up
It is not your gallon count, and it is not a weapon. A huge tumbler on the bars is how a brake lever disappears.
