Leather is the original choice for bikers as it is abrasion resistant, highly durable and if looked after should last you a long time.
Your leathers are supposed to fit like a second skin, this is important as they are the only thing between you and the tarmac. If they move, they won't do their job properly.
Choosing leathers is a very personal decision, a lot depends on the bike you ride, your riding style, when you ride and where. You may not want a one-piece suit for commuting, but they are a pre-requisite for track days.
All our leather motorcycle clothing has CE approved armour where you need it.
