A nice feature of this one is the on/off lever that can be easier for kids to see whether it’s on or off. The tube can also be positioned on the right or left, making it more convenient.

This benefits from having a whistle on the chest strap and a breathable mesh back panel. There’s also room for a rain jacket or sweater and snacks.

The Osprey Moki can be ideal for young or small kids because of its short length. It can also be a good choice if you’re environmentally conscious since it’s made from fully recycled materials.

A great feature of this one is the highly ventilated back panel to allow for increased air circulation for added comfort in warm weather.

It has a Quick Connect tube that connects magnetically to the strap on the opposite side (so the tube sits across your child’s chest), but this can help to keep it facing up to prevent dripping.

The Moki also has a whistle on the chest strap and a pocket for stashing small items.

3. Osprey Kitsuma 1.5 (best for youths)


  • Material: polyester/packcloth/foam
  • Fluid Capacity: 50 fluid ounces
  • Weight: 7.4 ounces
  • Length: 14 inches

This Osprey Kitsuma 1.5 is designed for women but can be an ideal choice for youths because of its length and adjustability. There’s also a front pocket that can be ideal for storing a phone.

The UpTake benefits from a locking bite valve to prevent drips and a Retrakt magnetic hose system that lets the valve automatically go back into place after each sip. This can stop the tube from moving around or getting in the way during bumpy bike rides.

When Should Kids Use A Hydration Pack?

A hydration pack can be much more convenient for your kids to carry on a bike ride than a water bottle. It can also usually let them carry a higher volume of water than standard water bottles and can mean they can take a sip without having to stop what they’re doing or slow down.

This means you can continue on your trip without having to wait for your child (and everyone else in your group) to stop, take their water bottle out of a holder and take a drink. Water bottles can also get pretty dirty while sitting in a holder, whereas the drinking valve on a hydration pack can stay a little cleaner and away from bike wheels.

A hydration pack is probably not required if your child is riding short distances. However, they can be particularly useful for longer rides or mountain biking over a few hours where your child may need more water than a single water bottle can hold. This can be especially important if you’re out cycling in the hot sun.

Video: Why Use a Hydration Pack for Cycling?

If you know your trip will last all day or several hours and you’ll be cycling or hiking in more remote areas with limited chances to refill your water bottle, then this can be a good time to use a hydration pack, as it can generally hold more water than your child’s water bottle.

However, some kids may decide to drink their water too quickly, which could be a downside, especially if you’re a distance away from being able to refill it.

Features To Help You Choose A Biking Hydration Pack For Kids


Ventilation can be important if you want the backpack to be comfortable for your child to wear. It can be even more important in hot climates.

The more comfortable it is, the more likely they are to want to use it. Having a breathable fabric, such as mesh panels, on the pack can increase ventilation around your child’s back and shoulders, which can help to minimize moisture from building up due to sweating.

Reservoir Size

The capacity of the reservoir determines how much water you’ll be able to hold in the pack. Just like many backpacks, the capacity is often stated in liters on product information. To find the fluid ounces, you can multiple the liter amount by 33.814 to find the capacity in fluid ounces.

The size of reservoir your child will need will usually depend on the duration of their bike ride or other activity. But you may also want to take into account the level of physical activity and how hot the weather is.

liquid reservoir fits inside hydration packPin

Most kids’ hydration packs usually have a reservoir capacity of around 1.5 to 2 liters. It can be important to note that not all hydration packs will include a reservoir or bladder, but most kids’ ones will generally include one.

If you choose to purchase a reservoir separately, it can be important to check whether it’s compatible with the intended pack. Some closures and clips may not be suitable for all types of reservoirs, even if the capacity is suitable.

Remember that the larger the capacity of the reservoir, the heavier it will be to carry when full, so smaller kids may struggle with larger capacity reservoirs.

Extra Storage Capacity

Additional space can be a useful feature to allow your child to carry extra gear, such as a jacket or snacks. The extra space your child will need in their pack will again depend on the length of time they plan to be using it.

Packs with up to 10 liters of additional space can be roomy enough for a couple of extra layers and some snacks. However, remember that the more your child carries in their pack, the heavier it will be, which may make them less likely to want to carry it.


The length of the pack can be important as this can give you an idea of whether it should fit your child or not. Before you choose, it can be a good idea to measure the length of your child’s torso, from the bottom of their neck to their lower back.

Ideally, the pack should sit no lower than your child’s lower back as this might affect their ability to move properly while doing activities.

Additional Features

There are some additional features that you might want to look out for, such as reflective trims or attachment points for a light. A whistle can also be a handy safety feature and can be found on the chest strap on some kids’ packs. But this can sometimes be a little too attractive for kids and they might want to use the whistle more often than you’d like.

Be Careful Of Valve Chewing

As you’ll probably know, some kids (and adults) like to chew on things. This can be a problem with some hydration packs because the valve can get damaged, which can affect the water flow or cause it to leak.

You can try to show your child to bite down using their back teeth rather than their front teeth. Or you can show your child how to turn the valve on and off so that they can switch the valve off after they’ve taken a sip, which can prevent it from leaking, even if it’s already suffered some damage.

Frequently Asked Questions

What Are The Downsides To Hydration Packs?

They can be heavy for some kids to carry, especially when full. They may also be more difficult to clean than a water bottle and can sometimes leak. It can also be difficult to tell how much water is left without opening it up.

Do Kids Drink More Water If They Wear A Hydration Pack?

They might drink more water since it’s easily accessible to them, meaning they can drink easily when thirsty. However, some kids might forget and could end up not drinking enough. Depending on the age of your child you may have to check their pack to make sure they’re drinking enough (and not drinking all of it at once).

Do I Need More Than One Bite Valve For My Hydration Pack?

Not necessarily but if your child tends to chew on the bite valve you might find it’s useful to have more than one so you can replace it if it gets broken.

At What Age Or Height Should Kids Move To An Adult Hydration Pack?

Some kids from 10 years old may find an adult pack more suitable. Women’s packs tend to be shorter to accommodate women’s shorter torsos so these can be ideal for kids around 5 feet tall or over.

Can Regular Backpacks Work With Hydration Bladders?

Some daypacks might be able to work with hydration bladders but not all of them, as you will need to make sure there are clips and tube portals to keep the tubes in place for convenience.

Drink Up! – Conclusion

We think the best hydration pack for kids is the Camelbak Mini M.U.L.E because of its durability and ease of use. It’s also lightweight, breathable, and includes a safety whistle.

A great runner-up is the Osprey Moki because it has a high level of ventilation on the back panel for comfort in warm weather and has an easy-to-use magnetic clip for the bite valve to keep it upright during bike rides.

Remember to measure the length of your child’s torso and check the length of any pack before you settle on one. If your child needs to carry a jacket with them you might want to opt for a hydration pack that has a little extra space inside.
