Product Details

It’s hard to imagine just how good the LS2 Stream II full-face motorcycle helmet is. Style, features and performance that surpass helmets costing literally twice the price, this helmet is an out-of-the-park home run. It starts with an aerodynamic, sport styled shell made from LS2’s proprietary Kinetic Polymer Alloy (KPA). This high-tech material uses nanotechnology to blend microscopic aramid fibers with a high-end polymer. This blend allows for amazing energy managing performance with managed flexibility that absorbs energy without the ricochet effect of inferior materials. The Stream II meets the ECE 22.06 rotational energy management specifications using Advanced Rotational Energy Management Technology (AREM), another LS2 proprietary process. The rear spoiler allows for dynamic flow-through ventilation. The 3D laser cut foam in the cheek pads, removeable, washable liner with special flex-crown comfort system is super comfortable and easy to keep fresh. 3 shells and 5 energy absorbing EPS liners make for a fit that is nothing short of amazing. The optically correct, Class A polycarbonate shield is Pinlock ready, for the ultimate in fog management (Pinlock sold separately). The overall finish and performance sets the Stream II at the forefront of full-face motorcycle helmets. Even those costing twice the price. Meets or exceeds ECE 22.06 and DOT FMVSS standards. Intermediate oval fit.

Sizing

Measuring your head for helmet fitment is the right place to start, but it is only a guideline. Different shapes of heads might require a slightly smaller or larger helmet in any given model. Trying on the model you are interested in is always recommended. A helmet should be as snug as possible, without being so tight that it will give you a headache. It’s best to be fitted by a professional.

1.Begin by measuring the circumference of your head with a tape measure or a lengthy string that you can line up with a ruler. Start above the ear and circle around completely, resting it in about a half inch above the eyebrows and at the fullest part in back. Measure multiple times to ensure you don't measure to small or large.

2.Compare your measurements with the size chart above. If your measurement falls between two sizes, opting for the larger size is recommended.
