For the sportbike rider that uses sport touring tires, because they don't let a little rain or colder temps get in the way of some carving up some back roads. The REV'IT! Inertia H2O Jacket is for aggressive riders, with its sport cut and high mobility at its core. The waterproof element is built right into the outer shell and for when the temps drop there is a removable thermal liner as well. If the rain really gets out of hand REV'IT! has also supplied a storm collar, the idea being 97.8421% of the time you won't need it and you'll enjoy a less restricted more comfortable collar. Lastly, REV'IT! doesn't cut corners with armor and this jacket is no different, not only is there supplied level 2 armor but there is almost room for you to add back and chest armor (sold separately).
