We all could use a little peace of mind on the trail, but that shouldn't mean packing on massive layers of body armor when we're heading out for endurance trail miles, or cross-country laps. Sweet Protection builds the Knee Guard to offer light, thin protection that elevates your confidence, without restricting movement or breathability. These guards use a thin layer of Sweet's proprietary SAS-TEC padding, which offers shock-absorbing properties, but still keeps things streamlined so you can easily toss them on under your shorts, even if they aren't super baggy. SAS-TEC has a knack for flexing to comfortably fit against your skin, and in this particular application, it's constructed with an articulated shape that is designed for your body position when you're in the saddle. Lightweight elastic fabric makes up the rest of the guard, allowing your skin to breathe easily, while keeping the pads locked in place so they stay secure, even when you're pedal mashing.
