“I wasn’t sure I needed elbow pads. But tried them out anyway. They fit great, I didn’t notice them at all during my ride. And then I fell! Did a sort of roll and hit my elbow on a rock! Didn’t feel a thing.”
“As someone who has expensive pads I never use because they don’t fit well, are too bulky and are uncomfortable… Finally, a lightweight pad for everyday use that I (literally) forget I have on. I love these pads so much I just purchased the elbow pads.”
“These are by far the best knee pads I have ever owned. They stay in place and have a lot of protection. I even ride XC trails with these! 10 out of 10.”
“Comfort and confidence, you forget you are wearing them but you know they are there… EXACTLY what you want in your pads/protection! I have an extensive ‘collection’ of knee and elbow pads, these are now my go-to pads.”
