Middle ground.

Situated in the middle of Leatt's product line, the Airflex Pro Knee Guard provides more protection than its lighter sibling, the Airflex, and less than the brand's range of hard shell options, presenting itself as a versatile knee shield that won't weigh you down on your trail, enduro, or all-mountain rides.

As part of Leatt's lightest, most flexible line, the Airflex Pro uses low-profile soft shell foam to guard the top, front, and sides of your knobby knees against damaging trail furniture. Protection comes in the form of 6mm perforated foam that's designed to be breathable and light, and it's attached to a MoistureCool and Airmesh sleeve responsible for moving with you as you ride and pulling moisture away from your skin to keep you cool. To keep the Airflex Pro secure, Leatt includes a silicone-printed knee grip and cuff so you aren't stopping trailside to tug a wandering knee guard back in place every few minutes.

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 cojohnson@backcountry.com.

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.

LOVE

  • 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

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.
