It is pronounced "Osso".

Ossososo's legend comes from the Himalayas: Longer than two thousand years ago there was a young yaks shepherd who was so in love with the mountains that left everything behind to live at the Snow Kingdom. He never came back.

Eversince, nomads who live at Butan, Tibet and Nepal belive that the young Ossososo became a god, and they thank him for allowing them to climb up his domains by throwing colored papers in the wind and proclaiming his name from tops and hills:

¡LHA GYAL-OSSOSOSO! (OSSOSOSO, you have triumphed!)

From OSSOSOSO our name went to OSSO so it would be easier and shorter, and finally, OS2O. A symmetric and international brand since we started selling abroad.

OS2O genetics come from the Pyrenees, but as a brand, it was born at the Himalayas, in Nepal.

Here you can read our founder's story.

Our mission is to make light and functional clothing for mountain use. The objective of the OS2O design team, is to enhance the characteristics of the technical fabrics that we develop by adding only the minimum, yet necessary, extras to make our clothes as functional as possible during the activity for which they were designed.

We produce our clothes at different spots worldwide. Currently, the main ones are placed in China, Spain, Nepal and Portugal, depending on the product. We are proud to say that the European production ratio is growing more than a 10% per year.

No, in any way. We frequently visit (sometimes by surprise) the factories in which we manufacture and we have never had any doubt about it. In addition, we work with companies with the BSCI certificate, which guarantees, among other things, the use of qualified adult labor and that complies with the labor laws of the country.

We try to design extremely durable garments that in most cases, are easy to repair so you won't have to buy a new one. Also, we have been using recycled polyester or coffee fabrics, and our DRW treatments do not pollute water. We do everything we can to keep our mountains clean.

Part of our business strategy is keeping our prices as low as possible during the whole year, that is one of the reasons why we do not sell to external stores to avoid intermediaries. On the other hand, we respect our customers who buy during any time of the year and who do not want to see how the products they just bought get cheaper just a few days later.
So, besides some sporadic promo (Black Friday), in OS2O we do not make sales. Prices are the same today as in 5 months. The only exception is when we have a last units product, so we place them in the Outlet / Sizes section until we run out of stock.

Although some shops have shown interest in offering our products in their catalogs, be do not sell to external stores. The reason is to avoid a price increase due to the added intermediaries. So we only sell online or in our own stores.

The OS2O Team has three sections: The Alpine, Skimo and Trail Teams. If you are interested in being part of it, you can send us your sports CV along with a mail of interests and objectives calendar at comunidad@os2o.com. Our Team Manager tries to answer all the candidacies.
