Key Materials Overview

18/8 Professional-Grade Stainless Steel

The body uses 18/8 stainless steel, containing approximately 18% chromium and 8% nickel, providing durability and resistance to corrosion.

Double-Wall Vacuum Insulation

The space between the inner and outer walls is evacuated to minimize heat transfer, helping beverages maintain their temperature for longer.

BPA-Free Lid Components

The lid and accent components use BPA-free plastic polymers, with clear components such as the top potentially made from Tritan™.

Silicone Rubber Gaskets

Silicone gaskets create a tight seal around the lid to help prevent leaks during transportation.

Griptec™ Non-Slip Base

The rubberized Griptec™ base provides additional traction and helps keep the tumbler stable on surfaces.
