Temperature retention is commonly described using terms like "double-wall" or "double-walled" insulation to keep drinks hot or cold longer. Reviews often note improved heat retention compared with some other mugs.
Common features include textured, non-slip grips, silicone sleeves or boots, and other non-slip surface treatments designed to improve grip and reduce the chance of slipping while carrying.
Lid materials commonly listed include general plastic materials, polypropylene, and HDPE (high-density polyethylene), depending on the model.
