10 Best Motorcycle Back Protector Review Guide

Updated May 2022


REVIT Seesoft Back Protector Insert

The revolutionary REVIT See Soft CE-Level 2 back protector is designed to absorb multiple impacts without compromising on comfort, ventilation or freedom of movement. The highly impact-resistant blend of Nitrille and Polynorbornene rubber results in a memory foam that is multi-impact rated and CE Certified to the highest level of prEN 1621-2:2010 level 2.

In the case of severe angular impact, the individual Memory Foam layers will shift relative to one another, resulting in impact dispersion over a larger effective surface area and therefore minimizing the energy that is transmitted to the spine and back. The Seesoft back protector performs extremely consistently in all weather conditions and is unaffected by temperature ranges from -4° F to +104° F (-20° C to +40° C).

Most REV’IT jackets are designed to accommodate a Seesoft CE Level 2 back protector insert. Newer jackets will have a marking on the protector pocket that indicates the matching type and size of the protector.

Icon D30 Back Protector Insert

An advanced, patented polymer, CE-rated D3O impact protectors are the latest advancement in protective armor. D3O® impact protectors utilize intelligent molecules that lock together on impact. Because of this, the impact protector can be made thinner and lighter, making a jacket more comfortable and easier to wear. However, this decreased size does not come at the expense of impact protection.
