Light weight makes it easier to keep the body in balance and increase swimming speed. 2. Upgrade soft bracket: the swimming snorkel is made of elastic material. The softer wide head cushion sits firmly on the head, adapts to the forehead and is comfortable to wear. The snap buckle allows easy adjustment of the strap and reduces pressure from the back of the head. 3.
