Alpinestars - SX-1 Plasma Knee Protector

The SX-1 Plasma Knee Protector are built to keep your knees and shins protected from hits, roost, and stray footpegs.

The SX-1 PLASMA Knee Protector features a PLASMA Knee Protector embedded into a highly ventilated semi-rigid frame construction for superior impact protection, while the integrated Dual Gear System (DGS) promotes the natural articulation of the knee. Key Features: Highly Comfortable: The Nucleon PLASMA knee protector is constructed from a USDA Certified Biobased viscoelastic material.

Why We Like It

We like how they manage to cover so much area without feeling like heavy, awkward armor.

Why It’ll Work for You

If your shins have already met pegs and rocks, adding this kind of protection is a smart move for future rides.

Variants / Options

Available in multiple sizes and sometimes youth versions to match different riders.

Key Features

  • Highly Comfortable: The Nucleon PLASMA knee protector is constructed from a USDA Certified Biobased viscoelastic material. Designed for multi-directional pliability, the protector molds to the knee for a close fit, effectively dissipating impact energy to deliver reliable protection.
  • Dual Density Co-Injected Frame for Support and Unrivalled Comfort: Engineered with a scooped lower extension made from a soft polymeric blend to avoid any pressure points associated with a hard edge from occurring as a result of the boot pushing against the protector. The same scooped design is also applied to the upper extension, preventing the protector from digging into the skin and causing discomfort while riding.
  • Controlled Natural Movement: Featuring the Dual Gear System (DGS) where both the upper and lower frames have integrated gear profiles that ensure a smooth hinge function to promote the natural articulation of the knee.
  • Ergonomic Frames with Versatile Sizing: The ergonomically sculpted frames of the SX-1 PLASMA Knee Protector feature strategically positioned rigid and flexible over-injected shells, providing a secure yet adaptive fit for a wide range of leg sizes.
  • Patella System Protection: The Patella System is engineered to offer full coverage of the knee cup regardless of the degree of extension while the rigid outer Patella System shell prevents injuries from handlebar strikes.
  • Lightweight knee protection with extensive protective coverage.
  • Upper and lower frames are constructed from a high-performance polymer for optimized levels of flexibility and strength as well as excellent weight-saving properties.
  • The upper and lower frames' integrated dual pivot hinge system follows the natural movement of the knee and keeps the protector well positioned while riding.
  • Frames feature a slim ergonomic design.
  • The dual strap closure system features a hook-and-loop closure with snap-fit buckles for easy in and out and a personalized, secure fit.
  • According to European statutory law, the CE mark is a conformity requirement for the marketing of this product. The following standards apply: Knee protector: EN 1621-1:2012 LEVEL 1

good experience so far
Size: 60 Count (Pack of 1)
I’ve been taking Qunol Brain Health for a little while now, and overall I’ve had a good experience with it. What stood out to me first was that it didn’t upset my stomach, which I’ve run into with other supplements. I feel like I’ve noticed a difference in my ability to stay focused during the day, especially when I’m working on tasks that usually make my mind wander. My energy levels also feel a bit steadier, without that late afternoon mental fog. The capsules are easy to swallow, and I like that it combines several ingredients aimed at supporting memory and concentration rather than having to take them separately. It’s obviously not an overnight miracle, but with consistent use I do feel sharper and more mentally “on.” The only downside for me is the price—it’s a little higher than some other brain supplements I’ve tried. But considering the quality and how it makes me feel, I think it’s worth it.

Definitely worth it!!
Size: 60 Count (Pack of 1)
After completing one bottle, I have to say that I have noticed a difference in not just my short term memory, but overall, how I can focus throughout the day. I'm on my second bottle now.

Memory Health
Size: 90 Count (Pack of 1)
I began Qunol Brain Health Memory Plus this year and am very pleased. I feel my memory is much better, although not perfect, I have more confidence while taking the product.
