Alpinestars - RK-1 Plasma Knee Brace

Anatomically profiled for all forms of off-road riding, the RK-1 PLASMA Knee Brace has been engineered to provide comfortable knee support while still being lightweight, breathable, and protective. This knee brace features a Nucleon PLASMA knee protector encased in an innovative hybrid frame construction, consisting of a flexible composite over-injected on a high-performance polymer blend to offer superb frame rigidity while still being flexible at the upper and lower strap areas.

  • This brace provides optimal structural integrity and support while being ultra-lightweight and adaptive, and thus reduces the risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus.

  • The replaceable triple segmented knee cups are constructed with a polyurethane outer shell backed with a Nucleon PLASMA protector for the optimum blend of impact protection, flexibility, and scratch resistance.

  • The self-centering knee cup and the strategically positioned upper and lower patella extensions ensure maximum coverage regardless of the flexion or extension angles.

  • The extremely stable, slim-design four-point hinge system perfectly follows the articulation of the knee while the extension stops, which are available in a range from 0 to 30 degrees, assist in setting the brace to the desired maximum opening angle.

  • The stainless-steel bushings in the four-point hinge system have an anti-oxidation treatment.

  • 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, the knee protector offers strong impact force dispersion and absorption while ensuring maximum coverage in all riding positions.

  • This knee brace features a Nucleon PLASMA knee protector encased in an innovative hybrid frame construction, consisting of a flexible composite over-injected on a high-performance polymer blend to offer superb frame rigidity while still being flexible at the upper and lower strap areas.

  • The replaceable triple segmented knee cups are constructed with a polyurethane outer shell backed with a Nucleon PLASMA protector for the optimum blend of impact protection, flexibility, and scratch resistance.

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

  • Soft-touch thermoformed padding ensures the highest levels of rider comfort while keeping the knee brace securely in position. Replaceable as a spare part.

  • Soft-touch thermoformed condyle padding comes in different thicknesses for a customized fit. Replaceable as a spare part.

  • Equipped with four individual straps backed with a non-slip material to ensure the knee brace remains securely in position while riding.

  • High tensile strength buckles are robust while still being flexible for easy strapping and adaptivity.

  • Central buckles are easily locked into the closed position by a keyhole snapping system.

  • Inner-knee central buckles are mounted internally inside the frames to avoid contact with the bike.

  • The CE-certified Level 1, RK-1 PLASMA Knee Brace provides optimal structural integrity and support while being ultra-lightweight and adaptive, and thus reduces the rider’s risk of sustaining injuries to the medial and lateral collateral ligament, the anterior and posterior cruciate ligament, and the lateral and medial meniscus.

Nice addition
Color: yellow
These aren’t the most gentle but a good gentle exfoliation. They are thick enough to keep the soap in. Fits a normal bar soap easily. With the quantity included you’ll be able to share as you’ll not need many yourself since they hold up to washing very well. The color is a nice off white- natural looking.

All natural alternative to loofas
Color: yellow, Color: yellow
I love that they are all natural, plant based, and exfoliating. Mine is already starting to stink a little, so I’ve started making sure that I’m squeezing all the water and soap out after using and it doesn’t smell anymore lol. I prefer these over using loofa with microplastics. They are effective, strong, thick, and size is for small or regular sized soaps. If u have a bigger soap just use the soap first and then lather with this. You will still have to switch out every once in a while (like a loofa). Amazing value for price ⭐️

Great exfoliation
Color: yellow
This does a beautiful job exfoliating, no more flakey legs. And it's gentle enough for the rest of my body. I'm on my 2nd bar of soap in my 1st bag and it's holding up well. I give it a good rinse after each use and hang it on a hook in my shower to dry. Well worth the money.

Extremely satisfied with my purchase.
Color: yellow
The ‘bag’ size is big enough to fit a LARGE (up to a 10 ounce bar of homemade/ handcut soap) bar or many tiny pieces. I am tired of using body wash (full of harmful chemicals) & a ‘pouf’ that may not be getting fully clean after throwing it in the washing machine periodically. The fabric quality is organic, natural & PREMIUM! It has little loops on the fabric which are great for lightly exfoliating & cleaning the skin, has a bead to keep opening closed and the string is long enough to fit around your wrist to hold it easily while bathing or showering. As far as effectiveness, it gets very bubbly if you get the fabric wet 1st & then make some traction (rub the wet bag back & forth onto the wet soap bar) between soap and the bag. For washing, use ‘wash bags’ (which are sold on Amazon & other retailers in many sizes) to keep them from being torn from buttons, zippers, etc on other items in the wash. With 8 in a pack, you should always have a clean one to use, while washing a previously used one. Rinse it out & Hang it after use to fully dry.
