    Airflex Pro Knee Guard

    Sure, scars look cool, but only to a point. So, strap into the Leatt Airflex Pro Knee Guard before you head out to crush (or crash) the next local enduro. Designed to split the difference between hard-shell and barely-there pads, the Airflex Pro uses low-profile soft-shell foam to protect the front, top, and sides of your knees without restricting your pedaling prowess. The 6mm foam is perforated to improve cooling and moisture-wicking airflow, and it’s stuck to a sleeve made of Airmesh and Moisture Cool fabrics, the better to keep the pads secure and your knee pits dry. There’s also silicone printing in key areas of the sleeve, so your pads stay where they belong and not around your ankles.

    • Quality knee protection in an ergonomic, comfortable design
    • Hybrid design blends reliable protection with soft comfort
    • 6mm foam is perforated for a well-ventilated fit and feel
    • Moisture-wicking, temp-regulating fabrics keep you cool
    • Silicone printing locks down a secure fit
    • Item #LBR004Z

    Comfy and good fit

    • Familiarity: I've used it several times
    • Fit: True to size

    I tried on 4 kneepads in total before settling on these. They had the best combination of protection, fit, and knee movement. I still notice them more than I'd like when pedaling, but don't think there would be much point to less protective kneepads.

    Produce quality and 'feel'

    • Fit: True to size
    • Size Bought: Large
    • Height: 5'8"
    • Weight: 160lbs

    I ordered both the elbow and the knee guard. I'll review the elbow in a separate post. My go to local ride has about a 1 hour plus uphill and after about an hour or so there's another 45 minute climb out. I usually dont put on my pads until after that first climb and remove them before that final climb out. Since I wanted to really test these guys out I put them on at the begining of the ride until th end of the ride....about 3 hours....really wanted to see if they would slip or be uncomfortable. Really didnt know they were there until I looked down at them. They are very comfortable! Now to be fair, on warm to hot know you'll feel the heat from them on a long climb but with the cooler days they are perfect. The material used feels beefier than my GFORMs. If I were a DH rider for sure I'd opt for a more serious product but I got this for my regular rides... Id recommend this product to my friends!

    Saved my knees!

    • Familiarity: I've put it through the wringer

    I went down hard and these pads saved my body. They stayed in place, protected the side of my knees as well as the front and top of the knees. I also use the corresponding elbow pads, I hardly notice them, comfortable, secure and protective.

    Quality Product

    • Familiarity: I've put it through the wringer

    I love these pads. However they would be better if there were thin wrap around velcro bands to help retain the pads in place better. The fit is good but they could be a bit tighter without constricting movement. if there were thin velcro adjustment straps this would be perfect. I might adapt my pair with my some aftermarket velcro straps.

    Finally a knee pad for a rowers quad!!!

    • Familiarity: I've used it several times

    I absolutely LOVE these!!!! I normally have a hard time finding knee pads that don’t squeeze the living bajeezes out of my upper legs. Normally I would wear them around my ankles until I rode downhill because they were too uncomfortable to wear while pedaling. I’m not overweight I just have large muscler quads from being a D1 college rower and they continue to stay large/muscler because I participate in figure competions. These are fantastic for when I do everything but downhill lift services at Deer Valley or Targhee. Barely notice them now.

    More Protection than G-Form

    • Familiarity: I've put it through the wringer

    These are my new favorite knee pads. I also have the G-Form Pro-X knee and elbow pads which I love for their comfort and breathability. These are almost as comfortable and breathable but offer a good amount more protection if you slam hard. I still wear the G-Forms on a lot of trail rides but when going to the bike park I'll wear these for the added protection.

    Best trail riding pads I've used

    • Familiarity: I've put it through the wringer

    Plenty of knee pads offer protection, but for trail riding the real keys are comfort and getting the pads to stay where they are put for the whole ride. These Leatt pads are very comfortable, provide ample protection (they've saved my knee more than once this season!), and stay in place even during long rugged rides. I don't notice them at all while pedaling. Yep, another great Leatt product, was, as always, easy to deal with and delivered the goods promptly and professionally.

    These are what I knee pads should be

    • Familiarity: I've used it several times

    I purchased these after using a popular knee pad for the last few years. After initially putting them on I thought they would be a bit much for all day rides. But after my first ride in them I was hooked. All day comfort and if I do end up taking a spill I feel like they will actually protect me anywhere throughout the knee area. Stoked to be riding with these for the rest of the season and it has the quality were I think I'll be using them for years to come

    Good all-day pad

    • Familiarity: I've used it once or twice and have initial impressions
    • Size Bought: Small
    • Height: 5'11"
    • Weight: 155lbs

    I like these because they're all-elastic, no Velcro. They're as padded as I would want a pad to be for pedaling in/wearing all day, and they have padding on the side of the knee, which is something too many similar pads lack. I'm pretty skinny, so I bought a Small - they're a little snug around the calf, but perfect around the thigh - do I just need to pedal more often?.. I like how high the upper part comes up, too: no gaper-gap on the chair lift.

    Best protection to comfort ratio

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'3"
    • Weight: 185lbs

    Wanted something light, but protective that stayed in place. I tried a couple of the zipper knee pads and while supper convenient for putting on and taking off, they didn't fit well at all. These fit great and I love that in addition to the main pad in the front, it has pads to the side and above this main pad to give in more protection in the case of the fall.

    Heavy Hittin' Knee Pads That Pedal Well

    • Familiarity: I've put it through the wringer

    For a frame of reference; I have a 21" thigh and 14" calf and run the size mediums, which fit relatively well, best of a bunch that I tried on. I ride everything from XC to DH, generally riding somewhere inbetween the two ends of the spectrum. I wanted a pad that could do it all and be comfortable for it all. I would say these are best suited for trail riding. I tried on a variety of pads on (G-Forms, Fox Launch Pros, Troy Lee Design Raids, Leatt Airflex, a few POC pads, didn't get a chance to try Dakine Hellion/Slayers though) and these fit the best.

    The knee foam is protective, but relatively so. Its definitely not going to compare with some more heavy duty pads out there, but for how well they fit and move with you when you pedal, they're pretty solid. There's also pretty good side and lower thigh protection.

    I like that they are stretch to fit - they don't have any straps, but don't need them. The closest style is going to be G-Forms, but I would say they feel more protective. They breath decently well - I've put in a few days in in 90+ degree weather and they're fine.

    If you're looking for a heavy hitting trail knee pad that pedals pretty well, look no further! Let me know if you have any questions on them or would like to put an order on in - my direct line is 801.204.4547 or email

    Excellent pads

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    Used the Leatt measuring guide and bought per their sizing. Used on two somewhat short rides so far. Fits very well and stayed in place. Did not have to adjust at all. Did not notice the pads at all. They did not inhibit pedaling and weren't hot (one ride was in upper 70s). One modest crash; landed square on one knee. Not super rocky area, but pad worked - didn't really notice hit and no bruises after. Very pleased with purchase so far.


    • Familiarity: I've used it several times

    I love these knee pads! For starters, the size small fits perfectly on my smaller legs. For reference, I am a size XS female, so finding mtb knee pads that fit is tricky! Secondly, they have a higher rise, so they extend up about 4 or 5 inches above my knee cap, for ultimate coverage, and to avoid the dreaded "gaper gap". I've only fallen once on them so far, and no issues yet! Great for trail/desert riding, but probably not the best for downhill. The one thing I am worried about is the lack of breathability on warmer days. So far, the warmest temps I have worn them in are high 60s and they have been good.

    Leatt airflex pro knee guard

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'1"
    • Weight: 180lbs

    These knee guards seem a bit sturdier than my pair of G-Form knee pads. If you are like me, and you're looking for some lighter knee pads to wear the entire ride...these are ok for shorter rides. I did find them to be a bit uncomfortable after a few hours. Other than that they are comfy, and stay in place! I've yet crash test them but, I'm sure that will be soon enough. I'll update my review once I do.
