How to measure your height:
1
Body height
To determine your exact height, stand on a flat surface without shoes, preferably with your back against a straight wall. Ensure that your head, shoulders and bottom are lightly touching the wall. Use a tape measure or folding rule and measure vertically from the highest point of your head (crown) to the sole of your foot. A second person can help you hold the tape measure straight and read the exact height.
2
Chest circumference
To measure your chest size correctly, place the measuring tape horizontally around your upper body at the fullest part of your chest. Ensure that the tape measure is not too tight and runs parallel to the floor. Breathe in and out normally to obtain a realistic measurement. It may be helpful to take the measurement in front of a mirror or ask a second person for assistance.
3
Waist circumference
The waist circumference is measured at the narrowest point of your torso – usually just above the navel. Ensure that the tape measure is horizontal and fits snugly, but does not cut into the skin. Breathe calmly and maintain a natural posture to obtain an accurate result.
4
Hip circumference
To measure your hip circumference, stand upright and wrap the tape measure horizontally around the widest part of your hips and buttocks. Ensure that the tape measure is flat and parallel to the floor. A second person or a mirror can help to take an accurate measurement.
5
Inside leg length
The inside leg length is measured along the inside of the leg from the crotch to the sole of the foot. Stand up straight, preferably barefoot. If possible, ask someone else to help you to obtain a more accurate measurement. A practical method is to measure a pair of trousers that fit well: Lay them flat and measure the inside leg length from the crotch to the bottom hem.

Buena relación calidad precio
Es muy bonito y cómodo. Su peso es liviano , ahora a ver la duración con el paso de los años de almohadillas y demás. Tiene unos gráficos super chulos. Y si lo compras en buena oferta de fcmoto merece la pena. Hace poco ruido a altas velocidades

Too much noise
Excellent helmet but the noise is killing me. Thus 4 stars. Let me explain.
I ride a 2007 Honda CBR1000RR. I was looking for a second helmet with inside sun visor. My primary helmet is Shoei NXR 2 Fortress.
I have this helmet 1 month. I don't know how it will be during the summer (I'm in Greece).
Pros:
1. Very light, same as my Shoei (both size S).
2. Big visor with excellent visibility, looking left or right and good when your chin touches the tank.
3. Quality product, well done made, awsome helmet.
Cons:
1. It makes noise to my left ear, noticeable above 80 km. I don't know what's fault. As the speed increases the noise increases too. Not recommended for long travel or without ear buds.
2. Difficult to tie or untie the strap with gloves.
