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.

      If the set screws were white the shelves would be perfect.
      Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
      I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.

      Solid Floating Shelves 🛠️🏠
      Color: Black, Number Of Shelves: 4, Size: 15.7in
      I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

      Good looking shelves and easy install - skip the included drywall anchors
      Color: Black, Number Of Shelves: 2, Size: 22in
      I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
