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.

I can't put a pic of me with my eyes barely open and a big red note bigger than Rudolph's!!!!!
I tried this item because of the description given on the website, unfortunately, I had a bad reaction to one use of it and I ended up in the Emergency Room at my local hospital.....what a waste of $$$ for me, especially because it said it was all natural.....I have never had a reaction to anything I have put on my face before....I still have a big red nose and one side of my face/nostril is full.....

It feels refreshing
I applied the Dewyhour Eye Balm Cool Stick, and it instantly feels refreshing, almost like a menthol sensation. It’s very cooling and soothing on the skin. However, I recommend not applying it too close to your eyes, as the cooling effect can be a bit strong in that area. Overall, it works well to hydrate and refresh the under-eye area, and I love the silky texture it leaves behind!

Desde que lo uso, he notado una gran diferencia: mis ojos lucen más despiertos y luminosos.
Esta maravilla es perfecta para esos días en los que las ojeras parecen más pronunciadas. Su fórmula ligera y fría proporciona un alivio inmediato, dejando la piel alrededor de mis ojos fresca y revitalizada. Lo mejor de todo es que su aplicación es súper sencilla: solo desliza la barra suavemente y siente cómo se derrite en la piel, brindando una sensación de frescura instantánea. 🙌 Además, es ideal para llevar en el bolso y usar en cualquier momento del día. Desde que lo uso, he notado una gran diferencia: mis ojos lucen más despiertos y luminosos. Sin duda, es un must-have en mi rutina de belleza.

It brightens before your eyes!
You know how some products need time before you see the difference, this one doesn’t. As soon as you apply it you can visibly see how light your under eye is. The formula is very rich, not too moist it just makes my under eyes look sooo vibrant!
