MANUFACTURER
Rab
The beginning of the story in 1981 in Sheffield (Great Britain) - Rabbi Carrington made the first sleeping bag that bore his name.
Sewn by hand and designed by his own genius eye, his designs were created with years of mountain experience, and demand soon emerged from both friends and the growing local climbing community.
Now, decades later, these durable structures can be found all over the world, wherever adventurers face the elements. 
Today, the brand's developers relentlessly adhere to Rab's strict standards, ingenuity and innovative spirit.
Under the Rab brand, durable, high-performance clothing and equipment are made that give you absolute protection, comfort and freedom in the mountains.
The production uses the most modern materials, as well as time-tested ones, such as the European premium tumor.
