HOT AND COLD FOR ON THE GO! The double-layered SIGG Hot & Cold bottles keep drinks hot or cold for around 24 hours thanks to vacuum insulation. The Hot & Cold bottles’ special insulation as well as their slim shape and leak protection make them a practical and reliable companion. The drinking cup can be attached to the top or bottom of the bottle. The collection made from high-quality stainless steel 18/8 is vacuum insulated and keeps drinks hot or cold for many hours. As is also the case with the classic SIGG aluminum bottles, trendy design, sustainability, functionality and Swiss quality standards enjoy top priority. H&C 0.75 L & 1 L do not have a tea filter.
