Oakley O-Frame 2.0 Pro MTB Goggle

Extra Small fit is designed to be smaller overall to fit kids and youth. If you are an adult you may want to look at the next size up unless you are used to shopping in the kids section.

Medium fit is considered average in terms of depth, width, and height. Medium-sized goggles tend to fit all sexes, along with growing teenagers.

Extra large fit is for those who tend to have issues finding the right size due to things being too small. XL-sized goggles not only have a wider fit but will have a much taller lens to provide that oversized look and the widest field of vision.

Small fit is designed to fit bigger kids, or adults with smaller faces. Generally, small-sized goggles are more narrow, shorter, and shallower than other frame sizes. If you wear a size Small helmet, then this should be the best size for you.

Large fit is designed to be a wider fit for those with bigger than average-sized heads. This size tends to fit large adult males the best. Do you wear a large size Helmet? Then this is the size to go with!

Asian fit goggles are designed to fit people with a more narrow nose bridge and higher cheekbones. The goggle offers more foam padding in the nasal portion of the goggle. In some instances, the goggles are less curved to minimize pressure on the cheeks.

Have you heard? SportRx makes prescription inserts to fit specifically inside of goggles. Not all prescriptions are compatible with the insert, so you may have to resort to OTG Goggles. OTG goggles have been designed to make wearing glasses underneath your goggles a little more comfortable. The foam padding typically has cut outs where the temples/arms of your glasses sit to minimize the pressure points of the goggles pushing the frames against your face.

Just about every goggle is now helmet-compatible but be sure to check for compatibility issues when opting for a more oversized spherical style. A great fitting goggle should have a seamless bond between the brim of the helmet to the top of the goggle to eliminate any extra space that will create a “gaper”. A gap that exposes your forehead to the sun, wind, snow, or dirt that can cause undesirable outcomes.
