Buying Guide


The first thing you need to worry about on your biking trip is how much gear you take along with you. Extra layers of clothes, equipment, food, spare tires, and so on just to name a few. If you’re only going on short rides, you’ll probably only take a few tools but in all-day mountain drives, you will most likely take more. Based on these circumstances, you will know how much capacity you’ll need.

Helmet Holder

Some backpacks use a specialized compartment into which you can stick your helmet. Manufacturers like OSPREY, use a LidLock system that is essentially a well-placed bungee cord to strap your helmet in.


Not only will you find it annoying if a pack swings around or rocks from side to side, but you will also find that the pack’s weight will take you off balance in corners with potentially dangerous results. Search for a pack with plenty of adjustable straps to tailor the fit and the way it fits on your back. The bag weight should be spread over the back and be supported by a hip strap. Thick padding on the shoulder straps will also help to keep you comfortable.


How much you’ll drink on your daily trip, or how much you’ll need to take to make it to the next source of water. The water reservoir in your bag has to carry the amount of water you’ll need. If the pack comes with a reservoir, then that is not a problem. Sometimes you’ll need to buy a reservoir separately so make sure to check that your pack will have enough. Unfortunately, not all reservoirs included are of exceptionally good quality. If you need to buy one, don’t get the cheapest possible because reservoirs that are poorly constructed appear to leak or even burst, which is less than optimal when you’re riding in the mountains.

Water Resistance

None of the backpacks here are inherently waterproof. Most of these have materials that offer a certain degree of water resistance, but nothing more than a slight drizzle and your pack’s contents may get wet. This is why we recommend purchasing a rain cover if there is a need for on worst cases.

Frequently Ask Questions

Are mountain bike backpacks waterproof?

Most of the materials provide some degree of water resistance but little more than a mild drizzle, and your pack’s contents can get soaked. Luckily this dilemma is a simple remedy, and it’s called a rain cover. These lightweight and reversible covers allow you to render your bag waterproof in seconds, and they are typically designed especially for the style of the pack, which ensures you can still get a perfect fit.

Are mountain bike backpacks machine washable?

Yeah, all of the packs we’ve included in our list are completely machine washable, however, you’ll want to make sure you pay attention to washing and maintenance guidelines since certain packs can need extra care to keep them running properly.

Can it carry a ski helmet?

Although a ski helmet can still be buckled to one of these bags, it is unlikely if either of the LidLock systems would operate on a ski helmet. This is because the system depends on the built-in ventilation of the bike helmet, which travels through the helmet all the way. On the other hand, ski helmets are sturdy all the way around so there will be no need to employ a ski helmet LidLock system.

Will mountain bike backpacks work for motorcycles?

There’s no excuse all of these packs wouldn’t fit as good on a motorcycle as on a mountain bike. Motorcycling, though, typically needs much more security than mountain bikes, so those packs are unlikely to be wide enough for that reason. Moreover, most bikes have on-board storage that can be used instead of a bag, since the additional weight isn’t too much of a challenge for automobiles and motorcycles. So we would recommend picking one from our guide on the best motorcycle backpacks instead.
