Alpinestars - Bionic Pro Plasma Knee Protector

Anatomically profiled for all forms of off-road riding, the Bionic Pro PLASMA Knee Protector has been engineered to be lightweight, breathable, comfortable and protective, and features a removable Nucleon PLASMA knee protector embedded into a chassis that is abrasion resistant on the outer and highly breathable on the inner for maximum performance.

  • Two independent thermoplastic shells are strategically positioned over the patella for enhanced levels of abrasion resistance and sliding performance, while also delivering additional impact performance.

  • The innovative slip joint construction ensures high levels of articulation while simultaneously ensuring the protector remains snugly in position.

  • The wide elasticated top strap delivers superior comfort and a secure closure.

  • Nucleon PLASMA is a viscoelastic material engineered from bio-based polymers and formed into a structure that is pliable in all directions while maintaining the ability to dissipate impact energies. Lightweight and highly ventilated, this knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage area in all riding positions.

  • Engineered from thermoplastic shells that offer enhanced levels of abrasion resistance and sliding performance, as well as impact protection.

  • Innovative slip joint construction provides riders with high levels of articulation and comfortable, snug fit that keeps the protector in place while riding.

  • Constructed from USDA certified bio-based eco-friendly and sustainable impact absorbing material.

  • Constructed with a soft tactile inner padding for enhanced rider comfort.

  • Pre-shaped construction features soft touch perforated stretchable padding for enhanced comfort and superior airflow, with extra lower and side padding for extended coverage.

  • The anatomically sculpted upper calf and upper hem silicon strips keep the protector secured in position.

  • Nucleon PLASMA knee protector is removable for easy cleaning.

Nice personal item for travel
Color: Black
I recently used this bag on my cruise. It fits perfectly under the seat for a personal item. The quality is nice and the bag is spacious to back many items. The only thing I didn’t like is that I kept having to adjust the straps due to them coming loose.

Hidden Gem!
Color: Desert
Huge and suitcase like on the inside. The zipper is the same color as the backpack and looks luxurious. Very soft and cushy even with heavy stuff in it. Like a laptop. Which there is a specific place for it that is cushioned. But my favorite by far is the clear pockets on the inside. I like that you can see what your getting out of your bag and where to find what. Also the outside pockets are really useful! And kinda incognito which is great for if you want to put valuables there. You can use this for travel, school and work. It's very versatile. Very good for organization. Comgortable and easygoing. Quality is 5/5.

Lovely Bag
Absolutely love this bag. The strap is a little tricky to adjust but once you do it’s are perfect. The whole thing came in a duster bag with material to protect the interior and integrity of the shape. Great product.
