STYLISH & ROBUST
LIKE AN ACTUAL GEM
DOUBLE-WALLED 18/8 STAINLESS STEEL
Like all other SIGG vacuum products, the Gemstone collection is double-walled with both inside and outside bodies as well as a vacuum space between them. Gemstone products are copper coated on the inside. This guarantees insulation that is among the best you can get in an insulated bottle.
30% LIGHTER THAN STANDARD BOTTLES
The flasks and food jars have an ultra-thin inside body which is made using a special spinning technology which is why it weighs 30% less. Thanks to high-precision welding, the vacuum gap inside the bottle has been reduced to a minimum. This results in a smaller bottle size compared to standard bottles with identical content.
