I bought this bag specifically for my Fly Trey Canard edition helmet. The helmet seems to be a little tight inside the bag, but overall it has a nice fit to it. It keeps the helmet snug. The material seems well padded and durable too. There are some other side pockets. I havent tried putting anything else in it besides the helmet. Im happy with the purchase.
I got this helmet bag last year when I purchased my Fly Helmet. It's got plenty of room for my helmet goggles and gloves inside the main compartment, though I generally put my goggles in my goggle case and my gloves in one of the zippered pockets. What I love about it are the vents so my helmet doesn't get stinky. Fly makes excellent products for a great value.
