This helmet works well with the behind the head headsets. The helmet is comfortable and the sizing guide seems close. I would recommend going with the smaller size if in between sizes as the helmet seem to run slightly big. The tails on the rear adjustable straps were a little long after getting the helmet set up with the headsets. I ended up cutting off approximately 6 inches of excess strap which left 2 inches of adjustment. The chin strap was adequate but was close to being a little short. The tinted portion of the visor can be removed for those not going for the RoboCop look. The helmet came with a cloth bag.
The helmet fits comfortably and works great with a behind the head headset.
