Protection doesn't always come to mind until you need it the most, but by then it's too late! Wearing the best mountain bike knee pads you can afford, though, can be the difference between riding whenever you fancy or having to sit out days, weeks or even months. 

Kneepads can do a lot to protect against bloody scrapes, cracked bones, swollen bruises or damaged ligaments.

With more riders tackling fast trails and big, technical descents on the best enduro mountain bikes, knee pads have become as essential as wearing the best mountain bike helmets. And that's because these days, wearing pads doesn't mean you have to settle for being sweaty and uncomfortable.

Nothing really!

At the heart of these lies a cup made of SAS-TEC SCL 2 viscoelastic foam – aka memory foam – that offers impressive levels of shock impact and absorption. This cup is removable so you can easily wash the fabric sleeve, and we found the lack of additional padding to the sides acceptable in light of the comfort it gains you. They're almost unrivaled for that among the best mountain bike knee pads, in fact.

The SAS-TEC pad warms up as you ride, too, which only makes it more malleable, and we've taken a number of falls in them and were pleased with the protection they gave. While these are our favorite pads for nearly any type of riding, the cheaper Knee Guard versions are worth looking at for comfortable pedaling too.

Find out why these Sweet Protection Knee Pads have become one of our go-to choice in our full review.  

Endura MT500 Lite knee pads

Excellent impact protection with super flexible and breathable performance

Colors: Black
Sizes: S, M, L

Reasons to buy

Ultra-flexible

Excellent ventilation

Light and low bulk
+
Rollable for storage

No penetration protection

Endura looked to impact protection specialist D30 and its Ghost protection for protection in the Lite knee pads. According to D30, Ghost is the 'thinnest and most flexible' protection it offers, yet it still exceeds EN 1621-1:2012 (Level 1) impact standards. 

The removable pad has an open grid structure with excellent ventilation, which stops these pads from feeling sweaty even when wearing them under riding pants. Also, the slimline construction means they're less prone to snagging and or dragging on those pants as you move. 

Another neat feature is that they roll up easily for stashing in a pocket or pack during a long climb. 

Like other softshell pads though, the MT500s offer no sharp-object penetration protection; really though, that's about the only flaw or trade-off when choosing a pad like this.

Leaning towards trail protection rather than full enduro

Rapha's move to add a set of knee pads to its blossoming MTB range is quite a departure for a brand that is best known for its road wear. Despite being the brand's first try at any protection, they have managed to develop one of our favorite knee pads on the market.

The Trail knee pads use a sleeve design to hold the pads in place and house an 'active polymer' insert from Rheon Labs. This insert has non-Newtonian properties which means it's flexible when pedaling but stiffens upon impact.

The combination of the comfortable and secure sleeve with flexible knee protection makes the Rapha Trail knee pads fit and forget even on long trail days. We never needed to hike them up after a big climb and a good flow of air through the insert helps keep them comfortable on the hottest of days. The pads are very slimline so there are no problems fitting them under the tightest race pants, yet the thin Rheon Labs insert has offered plenty of protection when we have needed it.

So good, Sam Hill put his name on them

Specifications

Removable protector: Yes
Colors: Black
Sizes: S, M, L, XL

Reasons to buy

+
Maximum coverage feels super reassuring on the trail
+
Super secure 100 percent of the time
+
All-day comfort

Reasons to avoid

-
Can be slightly stiff at the start of a cold ride

Designed by multi-time Enduro World Champ and downhill legend Sam Hill, his pro model pad from 7 Protection meets the protection and comfort sweet spot for enduro riding. 

Like the Sweet Protection pads listed above, the Sam Hill knee pads feature the same impact-absorbing SAS-TEC foam cup that stays flexible for pedaling comfort but hardens up upon impact. The removable pad provides plenty of protection over the knee and upper shin, and this pad is definitely one of the longest we've tested. 

Overall, the design is stretchy and lightweight, and a mesh backing is used to encourage airflow and ventilation. The sleeve uses silicone grippers on both the top and bottom openings, which have kept our pads in place 100 percent of the time. 

7 Protection has created a pad that almost exceeds the gravity riding knee pad dream list. We have a full review of the 7 Protection Sam Hill knee pads where we break down why the protection and comfort are deserving of the Sam Hill name.

Sizes: S, M, L, XL

Reasons to buy

+
Slide and slam protection
+
Impressive impact absorption
+
Secure fit in four sizes

The IXS Carve Race knee pads feature a 3D-molded piece of ‘Xmatter’ flexible material at its core, wrapping around the knee and extending down the shin. Additional padding is located on outer-knee and above-kneecap locations. An abrasion-resistant sleeve holds everything together and features silicone grippers to keep the pad from slipping. 

The Carve Race pads offer a large amount of protection and combine that with a relatively lightweight package that stays comfortable all day. They do get sweaty quickly on hotter days, but that is true with almost any knee pad that offers similar levels of protection.

POC VPD Air Legs

Low-level protection and weight but not light on your wallet

Specifications

Removable protector: No
Colors: Black only
Sizes: XS- XL

Reasons to buy

+
Incredibly lightweight
+
Easy to pull on and sold in five individual sizes
+
Fully packable and easy to carry
+
Low profile – can be worn under jeans/trousers
+
Contains smart technology insert

Reasons to avoid

-
Low level protection and can move under impacts
-
Silicone leaves a reverse POC logo on your skin
-
Some bunching at the back of the knee

According to POC, the VPD Air Legs is a pull-on knee pad aimed at riders looking for minimal padding and protection, but with high-level comfort and breathability. To achieve this, the knee pad combines a lightweight material body but with a high-tech VPD protective insert. 

VPD stands for ‘visco-elastic polymer dough’ a patented substance that is soft and pliable when you’re riding along but then stiffens under impact. The other trait of VPD is that it’s heat moldable, so put this pad on, ride for a bit and it’ll fit better. 

To keep the weight low, the back of the VPD Air is made from a fine Lycra mesh, which is naturally four-way stretch, meaning it fits all those curves and imperfections.  On the front is a slightly thicker material with a tighter weave and less stretch; the idea being that it keeps the insert centered on your knee. There’s also a seam across the middle of the knee that creates a small amount of articulation, so the pad moves with you. 

The smart insert adds around 30 percent to the cost, but the great fit of the VPD Air Legs – albeit with a gripper that's slightly too tight – makes that much easier to live with. So if you want lightweight trail protection and POC’s fabled build quality, this is the pad for you.

IXS Flow Evo+ Knee Guard review

(Image credit: Jim Bland)
A great option for near invisible protection and comfort in sweatier climates

Specifications

Removable protector: Yes
Colors: Grey, light brown
Sizes: XS, S, M, L, XL and XXL

Reasons to buy

+
Comfortable fit
+
Low weight and efficient wicking make them a dream to wear all-day
+
Superb levels of mobility

Reasons to avoid

-
The short overall design feels more exposed and you're more prone to the dreaded skin showing between the top of the pad and the shorts
-
Hardcore riders may want slightly more protection

The IXS Flow EVO+ knee guards are a soft-shell pad designed for all-around use, whether you are on a downcountry bike or a long-travel rig. The soft-shell nature of it means that full protection is traded for lightweight comfort. 

This set of knee pads from IXS uses an X-Matter 3D-molded viscoelastic pad that's designed to get firm upon impact and direct crash forces away from the knee joint. The pad's sleeve features a perforated mesh back panel along with silicone grippers to keep it in place. There is also a rear-mounted velcro strap on the lower portion of the sleeve. 

While hardcore riders may want to look elsewhere for the most protective knee pads, these ones offer a good blend of protection and pedal ability. However, the length can lead to a gap between the top of the sleeve and the bottom of some riders' shorts.

Leatt AirFlex Pro Knee Guard

(opens in new tab)
Extra venting creates a breathable pad with reasonable amount of protection

Specifications

Removable protector: No
Colors: Black, green
Sizes: S-XXL

Reasons to buy

+
Useful ventilation
+
CE-certified protection
+
Light weight
+
Five different sizes
+
Reasonable price

Reasons to avoid

-
Can stick rather than slide
-
No straps
-
Accurate sizing crucial
-
Slightly awkward to pull on

With a pre-curved design, Leatt's AirFlex Pro is made using 3D-molded soft padding, which is heavily perforated for max airflow. The primary protection comes from a highly flexible triangular segmented geodesic AirFlex Gel in that knee piece. Additionally, there is padding at the top of the knee and on either side. 

The additional perforation leads to a breezy pad that can be ridden all day long. The CE impact certification provides good peace of mind in the event of harder falls, too. In our testing experience, the pads did well to protect against lower-speed crashes. There are no straps so the pads rely on silicone grippers to stay in place, therefore we'd recommend checking sizing before buying. 

If the sizing suits you, though, they are a great option. Read about our experiences riding in the Leatt AirFlex Pro in our full review.

7 Protection Sam Hill Lite knee pad

Minimal weight and superb breathability but only low-to-medium protection

Specifications

Removable insert: Yes
Colors: Black
Sizes: S, M, L, XL

Reasons to buy

+
Incredibly lightweight
+
Available in five sizes
+
SAS-TEC insert stiffens under impact force
+
Low profile – can be worn under pants
+
Takes up minimal space in a pack

Reasons to avoid

-
Bunches up at the back of the knee
-
SAS-TEC pad needs removing to wash
-
Low level protection
-
Smart tech does bump up the price

Quite a few pads in the 7 Protection range feature top downhill rider Sam Hill's signature, and the Lite is sort of the baby bear of the family – in the sense that it has the lowest protection level and the lightest weight. Like the regular Sam Hill pad reviewed above, the Lite features an SAS-TEC protector and similar Lycra construction (albeit with less lateral protection), coupled with slimmer design and a lower price point.

The Lite uses a stretchy Lycra for the main body, which has a slight grid pattern in the surface to help wicking and it’s also Rip Stop. This literally does what it says on the tin – if you get a little nick or rip in the material, it won’t get any worse. 

Inside each pad is a branded SAS-TEC protector, a smart polymer that exhibits a viscoelastic behavior, which means if you introduce an impact force it stiffens significantly. SAS-TEC also molds to your body shape via a process called ‘heat contouring’, which is why the protector can feel quite hard in really cold weather. Pad stability is pretty good too due to silicone grippers on the top and bottom but the gripper on the top is quite harsh.

In theory, the 7 Protection Sam Hill Lite is made for riders who recognize the benefits of wearing a knee pad, but don’t really want to wear one. This pad weighs next to nothing (72g per knee), is easy to pull on, and even take off during a ride, but the flimsy construction is not as stable as the regular Sam Hill knee pad. It's not as comfy, either.

Fox Launch D30 Knee Guard

A secure knee pad with good protection

Specifications

Removable protector: No
Colors: Black
Sizes: S, M, L

Reasons to buy

+
Two straps for secure fit 
+
Good coverage 
+
D30 insert

Reasons to avoid

-
Limited ventilation

Fox's Launch D30 Knee Guard uses a D30 insert which gives it some top-in-class protection, similar to others on this list. The knee guards also successfully meet the EN1621-1 level 1 CE Certification. The Launch also features padding on the left and right of the D30 pad. 

The Launch D30 has a few features that make them a good option for riders looking for a pad with a secure fit. Unlike many pads that only have one strap or fastener, the Launch D30 has two, placed at the top and bottom of the sleeve. It also has a pre-curved, ergonomic fit. 

While the included hook and loop straps may mean increased stability, we appreciate that they may irritate some riders depending on the shape of their leg or knee.

Ion K-Pact Zip

Best for the quadzillas among us, featuring neoprene and a zipper

Zipper makes for easy on and off 

Reasons to avoid

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 main padding in the K-pact is manufactured by SAS-Tech. Secondary padding is located on the sides as well to keep your knees safe and sound when you take an unplanned digger. 

The sleeve is made from neoprene, which is an interesting addition not found on other knee pads. The brand says that it is Super Perforator neoprene and that while it doesn't breathe as well as some other materials, it is the most breathable neoprene that they've tried out. 

The K-Pact also features a side zipper for easy gearing up and when it's time to take them off. The zipper and two straps may bother some riders looking for a sleek pad, but those looking for a locked-in fit will appreciate it.

The best mountain bike knee pads: what you need to know

Should I wear knee pads mountain biking?

In short, if you are riding any sort of technical descents in which there is a risk that you could fall off it is worth investing in some of the best mountain bike knee pads. If you are going out on a light trail ride you obviously don't want to wear a heavy-duty pair of downhill  pads. Luckily, however, many brands offer a diverse range of products so you can pick the best mountain bike knee pads for your style of riding.

Protection comes down to two things: coverage and the protective padding itself. The protective padding should encapsulate the entire knee cap, as that's why you are wearing the pads in the first place. The sleeves of the pads should also cover the areas both above and below the actual knee cap. 

Protective paddings come in several forms, the most common of which are hard-shells and soft-shells. Hard-shells offer the most protection from sharp objects and hard impacts, but they are often not as comfortable. Soft-shells use technology that allows for a flexible pad that hardens on impact. This seems to be quickly taking over as the industry standard. 

Some pads only have protective padding over the knee cap, and others will also feature padding on the sides and in other locations. It's up to you as to what you prefer. 

How do you fit the best mountain bike knee pads?

All of the best mountain bike knee pads use a sleeve design with the protective padding stitched inside or on top. Many of the fabrics used to make the sleeves are designed to be breathable and stretchy in order to enhance comfort. Another measure to enhance comfort is pre-bent pads. In theory, this is done to help the pad better form to a rider's body, but everyone's knees and legs are different. 

Other factors such as straps and zippers could impact comfort and fit. Some riders prefer knee pads with straps, while others may prefer minimalistic pads that rely on silicone grippers to stay over the knee area. 

If possible it's best to try on a knee pad before buying to make sure the fit and comfort are okay. Mountain bike knee pads should be snug and secure, and you should also have full freedom of movement without the pad bunching, digging into the back of your knee or slipping out of place when you move.

Another thing that impacts comfort is breathability and ventilation, which will be discussed later. 

Do you get hot wearing mountain bike knee pads?

The hard truth is that wearing a pair of knee pads is always going to be hotter than having bare knees. If you have decided to buy a pair of the best mountain bike knee pads, however, you have probably decided that the safety benefits of pads outweigh the drawbacks of a hotter ride. 

It all comes down to both the material of the sleeve and whether it features any perforation or other ventilation. Pads with more ventilation features will generally be more breathable, and therefore comfortable.  

If you don't want to ride with mountain knee pads on but still want the protection, some pads offer neat features such as the ability to roll up and stash in a pack or pocket. Some riders also simply slide the pads down to rest just above their shoes when climbing or doing a lot of pedaling.
