Flybubble Note: Ultra-light gear must be handled with care to extend its lifespan. Mechanical stresses and improper handling can cause faster wear and tear compared to standard-weight gear. Designed for hike and fly activities, ultra-light gear prioritizes weight savings over durability and other factors. To avoid damage, refrain from extreme activities or excessive ground handling. Gentle treatment is crucial for longevity and safe operation.
