Selected Mask Strap Silicone Black.
The strap of the mask is usually made out of the same material as the skirt. The strap will attach via the buckles on the frame and loop around the back of the head. Straps have some give to them that help when fitting. The loosest fit possible while still maintaining a snug watertight seal is recommended. A mask that is adjusted too tight will often cause soreness on the bridge of one’s nose. The strap is also where the snorkel tube will be mounted.
