Both 25oz + 35oz Resa sizes are compatible with cold beverages and iced carbonated beverages.

To open the Ü-Turn™ Lid for sipping, align the mode indicator with the 'open' position indicated by the raised notch. To lock, turn + line up the mode indicator on the lid with the 'closed' position on the opposite side.

Resa can keep your beverages cold for 24+ hours. Your Resa should also keep ice for 24+ hours depending on how much ice you use and the starting temperature of the beverage you pour into the tumbler. It is recommended to use at least 50% ice for maximum temperature retention.

The silicone sleeve is removable for easy, deep cleaning. Simply pull the sleeve past the groove on the Resa and slide it off. The sleeves are all top-rack dishwasher safe. To put it back on, align the sleeve on the base of the product and slowly push upward from the base of the sleeve until the top of the sleeve slips past the groove.

To remove the ColdKey™ Straw for cleaning, twist the straw halfway between the open and close positions and pull up on the straw.

The Resa lid does not fit other Resa sizes or other BrüMate products.

Yes, both Resa sizes are compatible with our Magnetic Straw Covers to protect your straw when you're on the move.

Sure is. Resa lids are made from the equivalent of 4+ recycled water bottles, most finishes are dishwasher safe to reduce water usage, and the tumbler itself is inherently sustainable as it's reusable for life and eliminates the need for single-use plastics.
