There are days for the full on body armor, but pedal-heavy trail days are not them. For the days when pedaling to the top sends you up thousands of feet, but you want some protection on the descent, reach for the Ion K-Sleeve. Super-lightweight, the K-Sleeve is made from 3D shaped mesh, with lighter weight mesh on the back, and slightly heavier weight mesh on the front, so your knees can breathe from all angles. The pad is made from high-density 3D molded memory foam that is perforated for keeping sweat moving away from your skin. This pad does not use a heavy-duty hardcap, since lightweight is the goal, but it provides excellent protection from scrapes and cuts if a loose berm sends you flying off the trail.
