Interchangeable straps so you can match these with the rest of you look if you wanted! They feel very soft and comfy on the face with the triple layered foam with the microfleece facing contour. Super toric spherical lens on these gives you a good amount of vision in the periphery - pretty comparable to the ones below. They are a medium fit but where they stand out is the OTG feature so if you wear glasses, these are the ones you want!
