Thermos Bottle Sigg Gemstone Cup Selenite 1.1 L — Sigg 8789.00

The Sigg Gemstone Cup Selenite thermos bottle, 1.1 L, is an insulated container designed to keep hot and cold beverages for extended periods while on the move. Constructed and finished by Sigg, this model combines a large-capacity stainless interior with a screw-top closure and an exterior finish inspired by the selenite gemstone. The 1.1-litre volume accommodates multiple servings for hiking, travel, commuting or daily use, providing practical portable drink storage with reliable temperature retention.

Advantages

The thermos offers long-lasting thermal insulation suitable for both hot and cold drinks and a wide-mouth opening that simplifies filling, pouring and cleaning. Its durable exterior finish resists wear from regular outdoor and daily use, while the secure lid prevents leaks during transport. The 1.1 L capacity reduces the need for frequent refills and supports sharing or extended outings.

How to use

Preheat or precool the thermos by filling it briefly with hot or cold water, then emptying before adding the beverage to improve temperature retention.
