Hiking, mountain biking, canoeing... No matter what, Sigg's double-walled stainless steel thermo bottle from the Gemstone collection will be your reliable companion. It keeps your drink hot or cold for hours due to it's vacuum insulation. The cap can also be used as a cup, which makes drinking even easier. The 0.75-liter Obsidian bottle is as resistant and durable as stone and timeless like a gem.
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.
The embossed lines increase the structural strength of the products, making the already solid outer wall even more resistant to deformation.
