Absolutely. The 18/8 stainless steel body is dishwasher safe. For engraved bottles, we recommend hand washing to preserve the finish.

📏 What sizes are available?

Four sizes: 350ml, 500ml, 750ml and a generous 1 litre. The 350ml is the pocket size for the gym, the 1 litre covers a full day without refilling.
