Welcome to the world of OTSO, a brand born from a passion for endurance sports and a commitment to unparalleled performance. Standing for Think Sport, OTSO embodies the spirit of the wolf—strong, resilient, and relentless in the pursuit of excellence. At Runnerinn, we are proud to feature OTSO´s innovative range of products, meticulously designed for runners and triathletes who demand the best from their gear, from the starting line to the finish. While OTSO excels in creating technical apparel, socks, and headwear, their expertise truly shines in a critical area for every endurance athlete: hydration.

Master Your Hydration with OTSO Soft Flasks

For any serious runner or triathlete, hydration isn´t just about quenching thirst; it´s a fundamental component of performance, endurance, and recovery. OTSO understands this intimately, which is why their collection of soft flasks has become an essential tool for athletes worldwide. Say goodbye to the discomfort of bulky, sloshing hard bottles and embrace a smarter, more efficient way to carry your water, electrolytes, or gels.

OTSO soft flasks are engineered to be the perfect hydration solution for training and race day. Crafted from ultra-durable, flexible, and lightweight materials, these collapsible bottles are designed to shrink as you drink. This ingenious feature completely eliminates distracting water slosh, allowing you to focus on your pace and form. As the flask empties, it can be compressed and tucked away into a pocket, running vest, or belt, taking up virtually no space.

The design prioritizes functionality and ease of use when you´re on the move. Each OTSO soft flask is equipped with a high-flow bite valve that delivers a steady stream of fluid with minimal effort, ensuring you can hydrate quickly and efficiently without breaking your stride. The secure, leak-proof seal gives you the confidence to tackle technical trails and intense sprints without worrying about losing precious fluids.

Health and safety are paramount, which is why all OTSO soft flasks are 100% BPA-free and PVC-free. This guarantees that your water remains pure and taste-free, without any harmful chemicals leaching into your drink. Available in various sizes, from smaller 250ml flasks perfect for carrying concentrated energy gels to larger 500ml versions for longer runs, OTSO provides the versatility you need to customize your hydration and nutrition strategy. These flasks are designed to fit perfectly into the front pockets of most running hydration vests and belts, making them a seamless addition to your existing gear.

Whether you´re a marathoner chasing a new personal best, a triathlete managing complex nutritional needs across three disciplines, or a trail runner exploring remote peaks, OTSO provides the reliable, high-performance hydration system you need to push your limits. Equip yourself with an OTSO soft flask from Runnerinn and experience the freedom of lightweight, silent, and effortless hydration. Unleash your potential and let OTSO be your trusted companion on every run
