The SX-40 and SX-41 both come in a sporty design and the photochromic lenses excellently adapt to changing light conditions. They both feature bendable temple ends to hold them snugly to the head. The SX-40 features tapering side windshields to protect the eyes from side reflection, spray and dust. Whereas the SX-41 has a specially designed temple which is ideal for use with helmets and an extra band provides additional hold.
