Key Considerations To Buy Mountain Bike Pants

Waterproof or Non Waterproof

Mountain biking is a strenuous sport and involves a lot of sweating along with bearing with the external moisture. In pants, there is a distinct difference between waterproof and non-waterproof pants.

While the truly waterproof garments are ideal for wet weather and keep most of the water outside, it gets in the way of breathability and makes the rider uncomfortable. The moisture-proof membranes are bad at a disadvantage when it comes to breathability. They usually don’t have a built-in stretch, and the pants feel “crunchy.”

If you live in a region where it rains a lot, and it is cold most of the time, you should go for waterproof MTB pants. If you don’t, then go for softshell pants since they are substantially more comfortable, and they are treated with DWR so that the rain, splashes, and moisture can stay out.


The fabric of the pants you are wearing is important to keep the stretchability of the material in mind. Using the right textile in the right place can make or break pants. Getting pants with a good amount of stretch will help you feel comfortable and fit right into your body. It will also allow the materials to move with you as you ride.

Pants made of non-stretchable material will bunch, bind, pinch, and chafe which is not ideal for riding for long periods of time.


If you are someone who is not a fan of skinny-fitted jeans, usually, you need to change your preference when it comes to mountain bike pants. When you are riding a bike, you want your trousers to be form-fitting so that you can keep your knee pads in place and prevent the pants from flapping annoyingly with the wind and displacing the knee pads.

Moreover, flappy pants also carry the risk of catching on your saddle, which is a dangerous incident.

Picking pants that have articulated knees can help your pants fit better in the riding position so that your knee pads stay in place and your trousers don’t flap with the wind. Form-fitting trousers that are aerodynamic provide muscle support and a tight fit.


The fitness of a pant depends on the adjustability of the pants. To get a good fit, you need additional features such as look and hoop adjustment at the waist, allowing you to adjust your pants around the waist. Other options include Velcro, zips, or snaps around the ankle. This ensures that the lower cuff is fitting comfortably around your leg.

Mesh Lining

Special mesh linings or mesh panels on the sides of the garment are a good way to ensure that the sweat collected during long riding hours is wicked off quickly. Mesh lining helps to circulate air which increases ventilation and allows you to cool down easily.

Moreover, these linings are made up of stretch materials in the fashion of knitted fabric, giving them a good stretch and freedom of movement. Since the knit has enough space for the air to circulate, it can quickly cool your body and carry away the moisture.


Pockets are certainly a must need for riders to carry their personal belongings. You need pants that have secure pockets with zips so that your belongings don’t slip out. Two pockets are a must, but an additional one is a bonus.

Extra Padding

Some riding trousers feature extra padding underneath or abrasion-resistant materials around the high-wear areas such as the hips, shins, knees. Abrasion-resistant fabrics reduce the rub against the surface area of the mountain bikes. The road rash that occurs due to normal fabric is not a major concern with these abrasion-resistant paddings.


While the functional features of the pants, such as the ventilation, pockets, adjustment, and waist closure, can impact the prices of these pants, additional features like abrasion-resistant material cost more.

POC Resistance Pro is the most expensive among these pants, and Troy Lee Designers Sprints pants cost the most. However, the features differ a lot, and it depends on your budget and needs which one you pick for yourself.


Choosing mountain bike pants that fit your needs requires a great deal of contemplation due to the plethora of choices you have. Whether you are a downhill rider or an occasional trail rider, make sure you invest in pants that can keep you safe and comfortable at the same time.

Keep the considerations in mind, whether you need a waterproof material if you live in a wet climate or extra padding because you tend to ride for long hours. While additional features make a point of difference, remember that these bonuses do not come at the expense of the cost, fit, or comfort.
