FAST&LIGHT, is the concept that defines how we understand mountain activity and OS2O´s philosophy of design.


The feeling of moving light and free in the mountains, reaching further and faster, enjoying your own physical performance is something we find irresistible. Depart from a village, ascend light and in autonomy, progress by the summit ridge and descend at full speed. No vivac. Pure harmony with the mountain. A fair and pure game.




On the design side, our job is clear: improving functionality of our garments and reducing weight, maximizing the athlete´s performance in the mountain. With that objective in mind, we develop in the most specialized factories in the world fabrics and membranes extremely functional in a minimum weight. We test daily prototypes reaching for the perfect balance for garments to be worn from the beginning to the end of an activity. We optimize patterns that fit without limiting freedom of movements under high intensity efforts. We guarantee compatibility with external elements like helmets, harnesses or crampons, vital support elements in high altitude situations. We innovate continuously to optimizing the FAST&LIGHT technology.


That is how we conceive our products which is also our own philosophy of life indeed: live light, leave no trace, adapt to the external circumstances quickly, taking firm decisions, advancing through life in a FAST&LIGHT manner.
