ALPINESTARS MX ROAD BACK PROTECTOR SIZING CHART

The extremely lightweight Level 2 CE and UKCA certified Nucleon Flex Proi Full Back Protector Insert features a highly ventilated hybrid of Nucleon Cell and Nucleon Flex protectors for the optimum balance of force dispersion and flexibility, with a soft-touch 3D mesh liner for enhanced rider comfort. The back protector insert is a full-length back protector, about 22% longer than regular back protector inserts. The Nucleon Flex Proi is compatible with all Alpinestars’ sport and touring jackets that have released since Spring 2022, as all jackets have a double pocket to insert either a regular or longer back protector insert. The goal of the Nucleon Flex Proi is to deliver full-length coverage in terms of protection like a fixed back protector does, but with the practicality of an insert.

1. In terms of construction, the hybrid technology blends the best properties of Cell and Flex technologies to create an ultra-protective solution that delivers premium,  breathable performance, and maximum flexibility.

2. The protector has an ergonomically contoured dual zone outer shell constructed from an advanced polymeric blend with a solid Cell structure core framed by a moreflexible 3D Cell structure as the first line of defense; this is reinforced even further with the Nucleon Flex technology layer on the central back zone.

3. The protector is backed with a breathable soft-touch 3D mesh liner for maximum airflow and optimum rider comfort.

      Plush rug that’s super soft. WOW!
      Color: Natural (Yellow-white Ivory), Size: 6' x 7' (Natural)
      Beautiful and super plush! I use it as an outer blanket when cold weather camping. Like a modern day cave man. One of my favorite purchases. I avoid kneeling on it while it’s on my mattress fearing it might split the hide, or damage the stitching. It fits my queen size camper bed. Cant say enough!

      Big Investment for a Lifetime of Quality
      Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
      Several reviews mentioned a smell lingering with the sheepskin even after being unpacked a few days. I did notice the smell when I unpacked it, but I would expect a slight odor from such an item. It was not overpowering and is completely gone after one month of having it laid out on a chest in our bedroom. It is very functional, can be sat on, knelt on, etc, but is easily brushed off and looks great! The quality is very good…someone in my family is on it every night, and we have experienced no shedding whatsoever. Although the price is a big investment initially, I believe the quality is worthy. We plan to enjoy this beautiful sheepskin for a lifetime!

      Love it, but terrible smell at first
      Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
      Really soft & my dog loves it. I used it as a throw over my couch for decor. The smell when I took it out of the package was probably one of the worst smells I’ve ever smelled. Like old broccoli or something. I left it outside to air out all day and that was gone.

      Not premium quality! I've seen actual authentic ones before.
      Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
      Despite all the positive reviews, I believe this product is subpar. There are genuine sheep skin Hydes but this product is NOT it. There is no leather embossing showing authenticity, and many signs of strong chemical treatment. Smell is lingering and I've aired them for over two days. Not very comfortable since the fur is very thick and coarse, you would expect it to be softer for the price as well. Not premium quality. I ordered this for my children to sleep on at long evening Church services but now I will look to more niche sellers for a higher quality product.
