I had the original A-4 Chest Protector but it was basically worn out (most foam lining deteriorated). I really like how the A-4 Max is built stronger - more protection. Still has easy to adjust straps on the shoulder. I am 6'2" 200 lbs and got the size XL/XXL and it fits great.

Great protection and comfort!
If you’re looking for solid protection on the trails or track, the Alpinestars A-4 Max Chest Protector is definitely worth checking out. It’s lightweight but tough, giving you peace of mind without feeling bulky. The straps adjust easily, so you can get a snug fit that won’t shift around, even when you’re riding hard.

Light and comfortable. Fit on the shoulder straps is a little loose. I like the look of it too!
