Speed and Strength SS300 Moto Mercenary Helmet 5 5 2 2
This product has great features I like the quick clip for putting helmet on and removing. September 1, 2014
My new go-to helmet I received this helmet right before my trip to OBX Bike Week so I was able to get some good riding time in with it. I'll try to hit on all the major points... Looks: The looks alone are reason enough to buy this helmet. The flat black finish is awesome and the graphics have this "tattered" look to them, so the helmet already looks like it's seen the open road many times before. Features: The chin strap is my favorite part of this helmet, it latches and disconnects in seconds. It acts almost exactly like a seatbelt. Just pull the strap, slide the buckle into the slot, and you're done. It's so easy you can do it with your gloves on, for those of you who forget to put your helmet on before your gloves like myself. Like the description says, it does not come with the front vent. This wasn't a deal breaker for me but I did notice the helmet gets a little hot on long rides. Fit: My helmet size is between a medium and large so I opted for the large on this helmet. The sizing is perfect, it's a snug fit but not uncomfortable by any means. I also like that I didn't experience any "helmet lift" like I have with other half helmets. Overall I couldn't be happier with this helmet. It's become my new go-to helmet and at just over 60 bucks it's a no brainer. Get it. April 30, 2014
