LS2 Stream II America Helmet

The LS2 Stream II Helmet features an aerodynamic, sport styled shell made from LS2’s proprietary Kinetic Polymer Alloy (KPA). KPA uses nanotechnology to blend microscopic aramid fibers with a high-end polymer and 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, plus 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 overall finish and performance sets the Stream II at the forefront of full-face motorcycle helmets.

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.

A helmet should be as snug as possible without being so tight that it causes discomfort or headache.
