Built for all-day trail missions and rowdy descents, the Summit Knee Guards offer pedal-friendly protection without the bulk. Designed to stay in place and stay comfortable, these mountain bike knee guards feature a low-profile design that moves with you, so you can focus on the ride, not your gear.

At the core is a CE level 1 certified D3O® dual-density pad that absorbs impact while maintaining flexibility, making these ideal for riders who pedal as hard as they descend. The abrasion-resistant 4-way stretch CORDURA® fabric at the front shields against brush and trail hits, while breathable mesh panels on the back enhance airflow during climbs and hot laps. The extended sleeve design ensures a stay-put fit without straps, even through aggressive movement and variable terrain.

If you're looking for just the right balance of comfort, coverage, and confidence, the Summit Knee Guards are your go-to for everyday trail protection.

Pair with the Summit Elbow Guards and explore more men's mountain bike gear to complete your dirt-ready kit.

USE SIMPLE DETERGENTS WITH NO ADDITIVES Never use detergents with fabric softeners, perfumes or any additive type product. The general rule of thumb is the simpler the better. Many detergents with additives leave "surfactants" behind on a fabric's fibers that inhibit the technical performance. Typically the best detergents to use will have "Clear" or "Free" in their names. Don't pour the detergent directly onto the clothing, put it in the washer first, when you start the water. If something is not functionally working, but is not dirty, try rinsing it twice in warm to hot water. This will help get rid of the harmful surfactants. READ THE CONTENT CARE LABEL: On the inside of your garment, or on the hangcard, there are instructions for the care of that individual piece. On garments this will be on a side seam or back seam label. Follow those directions. On finer fabrics, use a "Gentle" cycle. Close all zippers, attach "hook and loop" closures on gloves YOU CAN USE THE DRYER, CAREFULLY: If you use a dryer be sure to use a lower / warm heat setting (Do NOT use a commercial dryer or a "Hot" setting). This will often restore the fabric and help the water and wind repellent qualities. If in doubt, hang the clothing to dry.

Reviews

Safety First for the knees

"Product is light, airy and comfortable. For size reference, I normally wear size medium in PI knee warmers, pants large (32" waist, 31" length). I ordered down a size from medium to small, due to my skinny legs. I'd consider extra-small to increase snugness, if Pearl Izumi offered that size. I wore them up climbs of 3,000+ ft and they weren't an issue on eMTB riding in Zone 2 (60% breathing capacity). Felt pretty good. My friends wore their other brands at their ankles climbing. I rode steep downhills of Oakridge, OR, where my butt hit rear tire, and felt no uncomfortableness or slipping down despite the sharp bend in knees. However, the top gripper on the thigh did pull away from under my chamois under-short's gripper. Most likely due to my skinny thighs. I rated this product a 5 star despite that last issue, because it wasn't a big deal and I could reposition the gripper. I like this product, and would like to try extra-small."

small

"This item ran very small. I chose the size after careful measuring and it was still very small."

— Gena C. (3/5)

Awesome

"Awesome fit, great protection in a streamlined package that easily fits under pants. Perfect level of protection for everyday riding. On sizing, the chart showed my calves as ‘large’ and my thighs as ‘medium’ so I went with medium and it’s great."

— Steve k. (5/5)

Very comfortable

"Very comfortable to wear and easy to use when pedaling. The slim profile provides protection for scrapes but would probably not prevent breaks. Good for intermediate blue trails and steeper black trails. Sizing consistent with Peal Izumi shorts."

— Brent C. (5/5)

Good fit

"Wore these on two rides so far. I ordered a size medium. Measurements for sizing seem accurate with these. Comfortable, still getting use to the more stiffness of the actual padding. Different than my last Fox pads, but so far I like them. I’ve learned to pay close attention to sizing with PI gear."

— Steve N. (4/5)

Barely noticeable on two rides so far.

"I'm 60+ and chose a size L. These knee pads (bought for an upcoming 56mi gravel ride) fit at the calf, but are loose at the thigh. I'm working to build up my quads, but it's a slow process. I would check the box that reads (snug below, and loose above my knee)."

— Andy M. (5/5)

Summit Knee Guards - Stop pestering me to post a review

"Summit Knee Guards - Stop pestering me to post a review. They are knee gaurds"

— Alex G. (5/5)

Great!

"Great!"

— Giovanni P. (5/5)

No wounded Knee

"So far no incidents fortunately but they are comfortable and I’m barely aware I’m wearing them."

— Mike G. (5/5)

Light and comfortable

"Lightweight protection for all day riding. These don't have the most robust protection but sure take the edge off a knee to the stem or slower speed crashes. These are my choice for "gravel" rides that might include some singletrack and janky doubletrack."

— Brent H. (5/5)
