Very pleased with it

I bought 2 pairs for my boys. They are 9 and 11, relatively skinny and short around 135cm each of them. Their legs have some muscle as they do football training and we cycle. We got the small size of the junior and they fir just fine. The straps could have enlarged sticky area for better adjustment.

Lightweight and well constructed

Just ordered 2 pairs S/M from the website for my 9 and 11yrs old boys. My boys are relatively short and tiny for their age and the straps of the knee protectors are too tight even on the loosest end. I believe they would stretch with the time, but would be a good option to have greater sticky area for proper fitment. The protector shell is good size and comfortable.

Не стоит своих денег

И лучше не брать для взрослого человека, Размер L/XL совсем не подходит когда сидишь согнутым коленом. Предназначен для совсем аалых детей до 10 лет. Вот для них возможно отличный вариант. Качество пластика: На месте накидки дырка начинает расширяться. Пробег 50км.
