What Mountain Bike Shorts To Buy?

You may be tempted to slip in to some old board shorts or cargo shorts for your mountain bike rides. When I first started, that is exactly what I did, but I soon learned that it was much better to wear proper mountain bike shorts. There are quite a few to choose from, so in this post I am going to help you decide what mountain bike shorts to buy. It isn’t complicated, but this information will hep you get some really good ones. I will also give you some recommendations.

What To Look For In Mountain Bike Shorts

Fabric and Construction

Mountain bike shorts, just like all mountain bike clothing are made for the job in hand. They are made to ensure that your movement isn’t restricted and you are as comfortable as possible. This is helped with the fabric used. Some mountain bike shorts are made from stretchy materials or they have strategically placed stretchy panels.

Mountain bike shorts are also made to be durable. This provides you with a little bit of protection when you crash, but it also makes them last longer. You will find that poor quality shorts will wear out on the seat quite quickly, from contact with the saddle.

If you ride in wet weather a lot, you may want to look into waterproof shorts. This makes a huge difference to your comfort, as your bum stays warm and dry.
Some mountain bike shorts have a DWR coating. DWR is a water repellent treatment that is applied to the fabric when it is made. You will need to renew it from time to time, as it can lose its effectiveness after repeated washing and wear against the saddle.


It is always good to be able to wear mountain bike shorts without the need for a belt. Belts can get in the way and can be really bad in a crash. So buying mountain bike shorts with decent adjustability is a good idea.
Look for mountain bike shorts with Velcro tags on the waist. These allow you to get perfect the fit. You can get the adjustable straps either inside or outside of the shorts. Make sure that Velcro straps are covered properly, as it can be scratchy on your skin if they are on the inside. If the Velcro straps are on the outside, they can catch on jerseys. Some shorts have big buckle straps which offer lots of adjustability and comfort.


The best way to stop the waist popping open accidentally is to buy shorts that have a press-stud fixing. Go for shorts with more than one studs and/or a small strip of Velcro to ensure security. Belt loops are a good idea if there are no waist adjusters.


Hip pockets are not exactly essential but are good for quick access to small change an energy bar or your phone. I prefer it when pockets have zips, so I don’t have to worry about losing anything.

Cargo pockets might sound like a good idea for carrying extra stuff, but personally, I don’t really use them. This is because they put all your stuff in the worst place for an accident. But the biggest issue with cargo pockets is that their contents bang against your thighs when pedalling, which is super annoying.


The length of your mountain bike shorts should be a consideration when buying. Longer shorts give you more protection against brambles and scrapes. Also, they fit over your mountain bike knee pads better.

Triple stitching, double popper buttons and chunky zips, result in a tough pair of shorts. Therefore, they will last you a long time.

The internal velcro tabs and silicone grip will keep them firmly in place. There is some thought gone in to the comfort of these men’s mountain bike shorts too. The mesh lining around the waist will wick away moisture, keeping you nice and comfy. Unfortunately, the only negative, is that the rear pocket is a bit too small. So it isn’t very useful.
