Head Tiger LSR+ Goggle The synergy of two different silicones ensures comfort & performance. The softer material, which is in contact with the skin, produces a better seal, whereas the more rigid silicone is used to create a stronger structure where the goggles are subject to mechanical stress. The exclusive RAS buckles are applied to the most rigid silicone, supporting the secure tension of the head strap & preventing deformation of the lens frame. The RAS buckles are positioned closer to the head, reducing water resistance & vibration. Colours: black/smoke, black/transparent, blue/transparent, magenta/transparent, orange/transparent
