Fly Racing Prizm Knee Guard Adult MTB Body Armor (Used)
Introducing the Prizm CE Level 1 approved knee protection system featuring Reaktiv Prizm Foam (RPF) technology. Working with a European protective foam developer the FLY Racing design team was able to produce heat activated foam that molds to the knee through body heat to make a perfect comfortable fit. RPF is high-density memory foam that has been sliced with a prismatic pattern to allow the pad to mold to the shape of the user. Once the foam conforms to the leg the guard stays put and is comfortable to wear all day. RPF foam is also body temperature sensitive, which means the knee guard becomes suppler as you ride for increased comfort while pedaling.
Not all CE markings are equal. The FLY Prizm Knee Guard is proper CE Level 1 certified to EN1621 / 2012 for knee protection. The Prizm knee guard has an internal tension pull that keeps the guard from sliding down the leg. Best of all the guard stays in place so you can count on it when it's needed, while being comfortable to wear mile after mile.
- RPF = Reaktiv Prizm Foam. Fly Racing has developed their own CE Approved protection. It is a high density memory foam that has been sliced with a prismatic pattern to allow the pad to mould to the shape of the user. The foam is also body temperature sensitive meaning it becomes more supple when you put the pad on increasing comfort when pedaling
- Kevlar front panels - heavy duty front panels with high abrasion resistance to increase durability of the pad
- Side knee protection
- Moisture wicking, antibacterial lycra pad liner
- 'Floating' neoprene patella cup with silicon printing to centralise the pad and prevent it from slipping down
- Strategically placed elastic banding with silicon printing to help prevent the pad from slipping down
- Open back design means you don't get material bunching up at the back of the knee when pedaling greatly increasing both comfort and breathability
- Asymmetric design to have left and right specific for improved fit and function
- Extensive use of flatlock stitching for increased strength, durability and comfort
- Innovative lacing system around the upper calf. Positioned above the widest point of the calf this helps prevent the pads from slipping down in use. Easy to use even with gloves on this system allows you to achieve perfect tension every time

HELMET
Sizing: Using a tape-measure, measure the circumference of your head just above the ears and across the forehead. Refer to the chart for proper helmet size.
Fitting: Open the chin straps and slide the helmet onto your head starting at the forehead. A helmet should feel snug. If it slides on easily it is too big. It should feel tight to pull down. Make sure the inner padding fits snug all around. You should feel the padding pressing against your cheeks and head. The last check for a proper fit is to test if it moves while wearing, there should be no movement if you shake your head. Place your hands on the helmet and move it front to back and side-to-side. If there is a lot of movement, try a size down.
