Description

Bio-Flex is a creation of Alpinestars itself and that is of course a certain guarantee that this is a perfect fit. In this case literally, which in the case of knee protectors is not always obvious.

Bio-Flex are mainly thin, lightweight protectors which do their job discreetly. The ergonomic design does not bother you at all and you wear them almost inconspicuously, while they are still very efficient with their flexible cell structure and thin design. Protection level 1 is not bad for something you hardly notice.

Alpinestars obviously knows what it's doing. The Italian motorcycle clothing manufacturer is a familiar name on and around the race track, and since they've been venturing more regularly into urban or casual style, they've been showing some very handsome stuff.

They come in pairs: left and right have a specific shape.
