Kailas is a climbing apparel and equipment company founded in 2003. We are committed to providing outdoor enthusiasts with ultralight products. Many of our products have won important awards, such as the ISPO Award and the European Outdoor Industry Award.

Sharing a passion for the outdoors, Kailas proudly partners with the IFSC, Tokyo Mountaineering Federation, Sport Climbing Australia, and the Chinese Mountaineering Association to engage with climbing communities worldwide.

Our mission at KAILAS is to promote and develop climbing and adventure sports globally. In pursuit of this, our R&D philosophy focuses on designing and manufacturing professional garments and equipment with a singular aim: to provide security and comfort in the most extreme environments.

Our achievements include being granted 71 awards both domestically and internationally, obtaining 29 unique product patents, reaching the summits of 43 unclimbed peaks, developing 1,391 sport climbing routes, partnering with 107 athletes, and participating in over 200 races each year.

The Kailas 5L, 8L, and 11/13L Running Vests embody our commitment to innovation and performance. Featuring a lightweight design, the backpacks weigh only 230g (medium size), making them suitable for trail running, marathons, and light hiking. Equipped with two 500ml TPU soft bottles, each weighing 38g, the rotating spout allows for convenient hydration, and the collapsible bottle design ensures stability during movement.

The 3D cutting technique used in the vest-style design positions the center of gravity higher on the torso, effectively distributing the weight across the shoulders, chest, and back. This balanced load transfer reduces stress on the hips and lower limbs, enabling dynamic balance, comfortable twisting, and free stretching during running.

The All-round Dial Fit (ADF) system allows for one-button, all-dimensional adjustments, enabling athletes to quickly and precisely customize the fit according to their body shape. This flexible and snug design promotes free breathing and unrestricted movement.

The running vest's multiple independent storage compartments facilitate quick access to essential gear, while the layered, stacked back compartment with breathable mesh provides ample space for a 1.5L water bladder. Trekking poles can be easily attached using the provided system.

Additional features include reflective printing for enhanced nighttime visibility, zippered pockets for valuables and documents, and a high-transparency fabric construction that enhances breathability and heat dissipation during activities. An eco-friendly drawstring bag is also included to keep the backpack clean.
