The KR-Cell back protector is a "stand alone" unit, meaning it has a waist strap and shoulder straps to hold it on your body without any connection to a jacket or suit. It is the lightest weight of the current selection of Alpinestars back protectors like this and is rated CE Level 1 protection.
This model has a flexible "3D" foam pad on the side that rests against your shirt which should be comfortable and allow a lot of air flow. The protective capability is provided by a molded honeycomb piece over that (the part you see in the photos). The honeycomb piece is much lighter than it looks.
I can see riders choosing this back protector for use under garments that don't have a pocket for a back pad or have a minimal/unrated back pad. This one could comfortably be worn for every day street use because is is lighter and more "breezy" against the skin as compared to the CE Level 2 back pads which would appeal more to racers and sport riders who want more serious protection.
*Accessories:* You can beef up the protection of this back protector by adding either a Nucleon Chest Protector Harness and/or a Tailbone Protector (see those links below). :: Paul, 11-13-17
