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

Nice little travel solution for jewelry
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Pink
Cute travel box for my jewelry. The necklace hangers aren’t all that snug, causing my necklaces to fall and tangle some. But otherwise, works as expected.

Very nice little box.
This is a great little jewelry box. I don’t have tons of jewelry right now, so this fits everything well, and the leather-look material is very nice. I like the simple design and organization, and it is a nice size to travel with. It looks really pretty sitting on my dresser and goes with the aesthetic of my home well.
