Mountain bikes are becoming ever more capable, and advancements in geometry and suspension have us gliding through rowdy terrain on short-travel full suspension mountain bikes that would push the DH bikes of yesteryear to their limit.

Even with these rock-and-root gobbling sleds, crashing is still very much a part of the ride, and quite often the first part of your body that meets the ground is your knees. Just like our bikes and helmets, knee pads have come a long way — gone are the days of the sweaty hard shells that were better suited to a sword fight than riding a mountain bike.

Knee pads have become nearly as essential as helmets, with everyone from enduro and downhill riders to even some XC guys and gals sporting joint protection. Below we've put together a selection of our favorite light-duty and heavy-duty knee pads.

Best knee pads for XC and trail

Best knee pads for mountain biking: Leatt AirFlex Pro knee pads

Leatt AirFlex Pro

Second skin fit with sweat-busting airflow

Removable protector: No | Velcro strap: No | Side padding: Yes

Super breathable
Low profile
Impressively priced 
Padding is pretty light
Lack of velcro closure may shorten life 

With a pre-curved design, Leatt's AirFlex Pro is made using 3D-moulded soft padding, which is heavily perforated for max airflow. Beyond the chief protector the side pads do well to fend off abrasions and, even though they are strapless, the AirFlex Pro stays put almost like a second skin. 

While the pad does well to fend off light impacts, when you get walloped you're still going to feel it. 

Best knee pads for mountain biking: Alpinestars Paragon knee pads

Alpinestars Paragon

Cross-country friendly knee pads

Removable protector: No | Velcro strap: No | Side padding: No

CE certified protector
Ventilation
Available in seven sizes
Value for money 
No adjustment or velcro closure 

Some of the lightest of the bunch, you might even be able to coax gram-conscious XC riders into padding up with the Alpinestars Paragon. With no straps, the Paragon features plenty of elasticated mesh and silicone detailing to keep everything in the right place.

The padding itself isn't a high-tech non-newtonian material like some of the others listed here but the polyurethane cup offers CE-certified impact protection and features a few ventilation holes, too. 

Best knee pads for mountain biking: Fox Launch Enduro knee pads

Fox Launch Enduro

Light and flexible but not quite enduro friendly

Removable protector: No | Velcro strap: No | Side padding: No

Super flexible
Abrasion-resistant material on the protector
Padding extends down over the top of the shin 
Can creep down your leg 

While the Launch has 'Enduro' in the name, they are a bit under-gunned for that particular style of riding. The Launch Enduros are lightweight, soft pads that allow for a full range of motion and the tube-style knee sleeve feels a bit like a heavy knee warmer at times. The chassis of the pad is made from a perforated neoprene with a lycra panel on the back of the knee to prevent pinching. The interior features plenty of silicon detailing to hold it in place.

The padding is asymmetrical; putting the padding where you need it on each leg and the light density soft foam is not only perforated but also articulated to cradle your kneecap extending a few centimeters down onto your shin.

Best knee pads for mountain biking: G-Form Elite knee pads

G-Form Elite

They look a little odd but will leave your knees bruise- and scrape free

Removable protector: No | Velcro strap: No | Side padding: Yes

Non-Newtonian padding
Flexible and pedal-friendly
Coverage 
Aesthetic likely to turn many off
Sizing runs small 

With the protector on the exterior of the pad, G-Form's Elite offers a unique aesthetic. G-Form uses what it calls RPT mapping to put the padding in the right places. The flexible non-newtonian armor offers decent coverage around the bony protrusions of your knee and dramatically dulls the force for rocks doing their best to bruise your joints.  

The lycra tube is strapless and features silicon bands designed to grip your skin, even when you get sweaty. We didn't have issues with them sliding down even on long rides because they are so tight and easy to position.

Best knee pads for mountain biking: Sweet Protection Light Knee Pads

Sweet Protection Light Knee Pad

A slim but tough knee pad option

Removable protector: Yes | Velcro strap: Top | Side padding: Yes

Plenty of protection but still lightweight, removable viscoelastic knee protector 
A bit warm 

Compact and lightweight, Sweet Protection has packed a surprising amount of protection into its Light Knee Pads. The single strap at the top holds the pads securely in place as you pedal, and the removable SAS-TEC protector offers plenty of impact protection.

The SP knee pads offer noticeably more protection than many trail-specific offerings but are slim enough not to get in the way of pedaling. Where they do fall a bit short is in the ventilation department, as the protector is not perforated and makes them a touch warm at times but the level of protection and fit more than make up for it. 

IXS Flow Evo+ knee guards

IXS Flow Evo+ knee guards

Lightweight pads that can take a beating

Removable protector: No | Velcro strap: Bottom | Side padding: No

Excellent knee coverage
Lightweight yet still tough 
Can creep up the leg
No side protection

Developed by mountain bike legend Hans 'No Way' Ray, these IXS pads use a integrated Xmatter foam to add an excellent level of protection for knee caps. There isn't any side padding but this lightweight pad packs away easily into a backpack if your a rider who has long climbs that they want to do with their knees out. 

We have been riding these pads for a number of years on all sorts of terrain and durability has been superb. They can creep a little on long pedalling sections however the bottom velcro strap keeps the pads locked in place on rowdy descents.

Best knee pads for mountain biking: Ion K-Pact Zip knee pads

Ion K-Pact Zip

Best for the quadzillas among us

Removable protector: Yes | Velcro strap: Top and bottom + zip | Side padding: Yes

Zip makes for easy on and off without sacrificing any comfort 
Large thigh opening may cause fit troubles for those with chicken legs 

The Ion K-Pact pads have been around for a while, and the SAS-Tech padding and ample secondary padding keep your knees safe and sound when you take an unplanned digger. 

With top and bottom velcro straps, they stay in place even when pedaling and there is plenty of flexibility on offer, too. A bit warm out on the trail, the built-in zipper makes the Ion pads a jiffy to put on or take off on-the-fly — even better, once they're on you'd never know there is a zipper there. K-Pact pads offer excellent protection, arguably the best closure of the bunch and, to top it off, they aren't as expensive as some of the options listed here.

Best knee pads for mountain biking: 661 DBO KNEE

661 DBO knee pad

Heavy-wearing, heavy-duty knee pads

Removable protector: No | Velcro strap: Top | Side padding: Yes

Top-notch side protection and abrasion resistance
D30 protector 
Single strap gives limited adjustability

661 has been protecting mountain bikers for years and their DBO kneepad continues where the venerable and very popular EVO kneepad left off. 661 took the Evo design and remodeled it to offer equal levels of protection but at a lower price.

The main protection is still handled by a D3O T5 Evo insert which remains flexible until met with an impact causing it to become firm, this has allowed the DBO pad to be rated to provide EN 1621:1 level 1 protection. There are side pads as well that add a little extra coverage from knocks too. A single top strap keeps the pads in place whilst keeping the overall bulk down and limiting areas of possible discomfort. 661's Padlock system allows you to connect the pads to the Evo shorts to prevent them from going anywhere in the event of a crash.

Best knee pads for mountain biking: Troy Lee Designs Raid knee pads

Troy Lee Designs Raid

Ready for rowdyness

Removable protector: Yes | Velcro strap: Top | Side padding: Yes

Good balance of pedalling comfort and protection 
Expensive
Ventilation not great 

Troy Lee Design's Raid is pitched towards the rowdier end of the spectrum with plenty of D30 padding and foam encasing your knee. The individual protectors are anatomically placed to match the bony outcrops on each knee and extend well down the shin. Keeping everything in place is a single velcro strap along with silicone grippers, which articulate and flex quite well with your leg.

The rear of the pad features lightweight mesh for ventilation but they are still quite warm. For this level of protection expect to fork out as the Raid's are anything but cheap.

Best knee pads for mountain biking: Race Face Ambush knee pads

Race Face Ambush

Likely to survive a nuclear blast

Removable protector: Yes | Velcro strap: Top and bottom | Side padding: Yes

Pads can be slid over shoes 
Inner knee coverage is slightly lacking 

One of the burlier sets of knee pads on offer from Race Face the Ambush are likely to survive anything you throw at them and keep your knees abrasion and bruise-free. With a D30 pad looking after your kneecap, there is a decent amount of polyurethane padding on the outside of the knee; however, the Ambush leaves the inside of your knee susceptible to knocks from the top tube. 

With double velcro straps (one above the knee and one below) they are not going anywhere. The sleeve is made from perforated neoprene lined with terry cloth. Despite the protection on offer, the pads still retain quite a bit of flex, and pedal well, but they tend to get pretty sweaty on longer climbs and long pedaling sections of trail.

Best knee pads for mountain biking: 7iDp Sam Hill knee pads

7iDp Sam Hill

So good, Sam Hill put his name on them

Removable protector: Yes | Velcro strap: No | Side padding: Yes

Fit: stays in place like a seized bolt 
Extra length might not suit everyone 

Designed by three-time Enduro World Champ Sam Hill, his pro model pad from 7iDP is an evolution of the Transition pad — he wanted more protection without sacrificing comfort. The result is a soft knee pad built around a breathable lycra sock complete with a mesh back. SAS-Tec makes the removable protector, a non-newtonian material that is soft and malleable but hardens upon impact.

There's a bit of added foam protection around the side, and the lycra sleeve and protector are noticeably longer than most. This not only plays a role in helping them stay in place while pedaling, it also prevents a gap between the bottom of your shorts and the top of your kneepads. Instead of a velcro strap at the top or bottom, the Sam Hill pads feature silicon grippers.

How to pick the best knee pads for mountain biking

Fit and comfort

Even if a knee pad uses new-fangled materials, has fantastic ventilation, weighs almost nothing and also has a built-in force field that prevents sharp rocks from stabbing your knees, if they are uncomfortable you probably won't wear them. The latest crop of knee pads are pre-bent with ergonomic cupped protectors to help them stay in the right spot. Most rely on a combination of silicone grippers and velcro straps to prevent the pad from sliding around, though there are a few strapless designs — these models require a particularly snug fit which may get progressively looser over time as the elastic loses some of its spring.

Beyond looking for a pad that matches the shape of your legs, the combination of length, circumference, fasteners, silicone grippers, cutouts, seams, and zips will all play a role in overall comfort. If any of these factors aren't quite right, they may pinch or chafe.

Protection

Knee pads are available in all different levels of protection from lightweight lycra sleeves with a bit of foam padding sewn in, to those that feature removable viscoelastic or non-newtonian protectors designed to blunt and disperse heavy slams. While these modern materials are more efficient and often lighter weight than standard polyurethane foam, they also come with a significant price tag. 

Each pad will also offer different amounts of coverage but at the very least should extend well beyond just the knee cap itself. Burlier options will also feature secondary padding to protect other boney outcrops on the sides of the knee. 

Ventilation

As a general rule, the more padding on offer, the warmer it will be. Most feature moisture-wicking fabrics and are perforated to allow some airflow, but there is only so much heat these features can disperse. In this regard, it's about finding a balance between how much protection you need and how sweaty you're going to get. 

Durability

Given that the whole idea of a knee pad is to protect your limbs from dirt, rocks and roots when things go pear-shaped, the materials used throughout the pad need to be robust. Quite often, canvas, kevlar or similarly tough materials will be used over the cap to prevent rips and tears. Quite a few of the knee pads below also feature a removable protector that can be pulled out for washing or even replaced if damaged.
