The Alpinestars Troop-Air Pro Textile Jacket-Black / Fluo Red has the following specification I bought this to wear under a Tech Air 3 V2. it's comfortable and gives a lot of ventilation. I swapped out the back and chest armour from my old Alpinestars Andes jacket, it's great that Alpinestars don't keep changing the size and shape of armour on their products.
