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.

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.
