First Leather jacket - last week I purchased the Indy jacket after deliberating for a few weeks..(Ok maybe a month or two) and I could not be happier. I looked at a few options, RST......etc but narrowed it down to the Daniese Air, the Alpine Stars GP Plus and the Indy. Previously I have used my touring Textile ( Teknic Freeway)and another Textile that was given to me, both more winter than summer jackets. The hesitation was do I go vented or not? Will I regret it on the colder mornings? How will a vented jacket compare to non vented upon impact...... In the end, the Indy jacket was the best fit, so I went with it. So...On colder mornings I layer up and this works to keep the wind chill out, and today was the first really hot day that I have riden in and its fantastic!! The leather is certainly warmer that textile, no question, but the vented leather is so well - vented. It flows volumes of air. At the lights you certainly feel the heat rising from the bike and other cars around you but once on the move the air passes flows freely to cool you. The other plus is that its a little lighter that non vented jackets so it makes it easier to live with when not on the bike. The trade off will be in safety I guess. Zips, and general finish of the jacket is very good, not as good as some of the higher range jackets $(700 plus )so you do get what you pay for but for the money I felt it was slightly better that others in the price range of around 400.00 Cheers, hope that this may assist other newies like me decide one way or the other.
