STYLISH & ROBUST
LIKE AN ACTUAL GEM
DOUBLE-WALLED 18/8 STAINLESS STEEL
Like all other SIGG vacuum products, the bottles of the Gemstone collection are 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.
GROOVES FOR ENHANCED STABILITY
The embossed lines increase the structural strength of the products, making the already solid outer wall even more resistant to deformation.
