Grip the goggles by the edges of the eyecups. Press the goggles against your eyes. Guide the backstrap up and over your head. Adjust the backstrap to get a comfortable and secure fit. Pull the backstrap over your head from the back to remove the goggles.
Hold the goggles so that the inside of the lenses are facing towards you. Place your thumbs at the bottom of the eyecups, then wrap your pointer fingers around the tops of the frames. Your right thumb should be resting on the right cup, with your left thumb on the left cup.  Flip the backstrap over to the front side of the goggles to keep it out of the way while you put them on. Alternatively, you can start with the backstrap around your neck and the goggles dangling in front of you. Bring the goggles up to your face, guiding the eyecups over your eyes. Press your fingers gently into the edges of the frames. You should feel a light suction as they form a seal on the skin around your eyes.  Only the soft rubber around the inside of the eyecups should come into contact with your face. Make sure the eyecups don’t pinch or tug at your skin. If they do, you may need to remove and reposition them until they feel comfortable. Avoid touching the lenses themselves. Doing so could leave behind smudges and obstruct your vision underwater. Keeping the goggles pressed to your eyes with one hand, use your other hand to position the strap until it rests against the back of your head at around eye level. When viewed from the side, the strap and the eyepieces should form a straight horizontal line. If the strap doesn’t feel comfortable where it is, slide it up rather than down. The lower it is, the more likely your goggles will be to slip while you’re swimming. Pull the loose end of the rubber strap  through the buckle slot on the side of the frame to tighten your goggles. If you want to loosen them instead, lift up on the buckle lever and pull the strap out to put a little slack in it. Your goggles should be snug, but not tight. Before you dive in, double-check that the goggles fit securely all the way around your eye sockets and that you can see clearly out of both lenses. When you’re ready to take off your goggles, simply reverse the motion you used to put them on. Reach behind your ears and slide your thumbs underneath the sides of the backstrap, then lift it over your crown until the goggles come free. Don’t try to remove your goggles by pulling on the eyecups. If you’re not careful, they could snap back and hit you in the face!
