Not Drinking Enough Water During Lengthy Cardio? These 10 Hydration Packs Are Your Answer.

This one blew us away in testing, so much so that it made the grade for the Men’s Health 2025 Outdoor Awards. What’s to like? A lot, turns out. A one-of-a-kind hose and valve system ensures that sips are nice and chilly, even when you’re nearing the end of your supply. That kind of refreshment, plus the fit of this pack, make it next-level.

While perhaps a little heftier than other packs, we could hardly tell during testing as the straps and support created a second skin-like wear. That made it great for any kind of outing, from hikes in Joshua Tree to full days at a music festival. Your water truly stays cold for up to 24 hours, something a lot of packs just can’t pull off.

Now, in addition to looking good, the pack offers some serious tech. That 40-ounce hydration system comes with a stainless steel vessel fit with a mouth wide enough for ice. It also comes with a special straw to keep plastic from hanging out in your water supply all day. No leaks, kink-free delivery, and coldness every time by way of a fantastic drinking valve.

Pros

• Lightweight
• Two liters of water storage in main bladder
• Weather-resistant

When empty, this hydration pack weighs just over one pound, so between the two liters of water it holds and whatever essentials you wish to carry around, you’ll be able to travel light. Best, it’s a bargain and often on sale. No, it does not have some of the special features that the others have, but if you’re just looking to stay hydrated on the go, you’re in good shape.

Breathable mesh nylon straps keep you cool, and the entire outer shell is nylon and weather-resistant. Not bad for a pack that comes in well under $30. Just give it a good clean to begin with if you don’t want to taste any of those plastic notes.

Runners in our testing group were really drawn to this long-standing vest from Salomon. With a plethora of colors and sizes, you’re bound to get the perfect fit and look. No matter how hard or long we ran, the pair of soft water flasks just didn’t move, which is exactly what you want either on the pavement or the trail for extended periods.

The Y-shaped design allows for ample arm motion and the breathable fabric is great for those big and strenuous outings. You get eight pockets in total and the band can be adjusted even on the fly to keep things snug and aerodynamic.

CamelBak has been a revolutionary brand in the hydration pack game, and this product is another great issue from the brand. You get the signature hose and nozzle in an extremely lightweight build at just 12 ounces. Your water capacity is 1.5 liters and the mesh harness kept us from overheating when on long journeys.

You can fit a laptop in the pack with a low bladder (or water removed entirely), making it a nice hybrid of sorts you can use on commutes to the office. Best, you can up your water capacity by utilizing that stretch pocket and packing an extra full bottle for hotter or longer adventures.

We did, however, notice that the pack can feel a little awkward when being really active as it does not come with a stabilizing and supportive waist belt.

Meant for all-day adventures, this Teton model is one of the best hydration packs for mountain biking or heavy-duty hiking. And it very much looks the part, a bit burlier than some. The pack itself is roomy so you can fit plenty of gear in addition to your water, which our testers found to stay chilled for approximately five hours.

There are padding pretty much everywhere, making this pack a go-to for backcountry enthusiasts who like to log the trail miles. The three-liter bladder is a good size and the well-placed hydration ports make sipping convenient. The paddlers and skiers among us loved the pack too. There’s even bungee cords to tie on even more gear, like trekking poles.

And the coolest part might just be the rain cover, which stows away neatly and pops out like a parachute when you need it most.

Trail running puts a little more stress on runner and vest. You need some SUV-like qualities to keep up with all those bumps along the route. This one impressed even our most discerning dirt joggers, with its ergonomic and stay-in-place fit. Adjusting cords and straps even while running is no problem and the stretchy front pockets are great for stashing extra fuel in the form of gels and protein bars.

There are nice safety features too, like pockets compatible with personal locator beacons and the ability to add extra water with an additional hydration reservoir. You can basically stow three liters of water and a couple of sandwiches in this one without adding bulk and it stays secure on your chest.

The Raptor has a special helmet attachment point for easy access while crushing some mileage, or just keeping you hydrated on your daily commute in the bike lane. The hip belt keeps your pack securely in place, but don’t fear sweat, because the whole pack is designed to be breathable.

The sternum strap magnet is a nice touch for convenient sipping and the slash pocket is great as it’ll protect sensitive items like sunglasses. Our bikers fell for this bag, drawn to the roll-up tool pouch, helmet latch, and superior ventilation. There are even hip belt pockets to store those protein pouches or other snacks.

Nathan has really made a name for itself in the hydration pack genre, dropping more and more thoughtful, well-made options. It’s one of those brands with actual invested staff putting real time in the field, testing pet projects before fine-tuning them and releasing them into the wild. Here’s a great example, a streamlined hydration vest created with both the road runner and the long-distance runner very much front and center.

For starters, it comes with a 1.5-liter bladder that’s easy to access and includes a quality spout. That bladder is easy to remove and clean and stays nice and secure even when you’re very much in the midst of pounding pavement. There’s more storage than you might think given the bag’s small size, the wrap-around reflective details are great for safety, and there’s even room for spare water in the front (up to 20 ounces). Oh, and did we mention that the fit is just about perfect? That’s held true for our one tester during 20-mile long runs into the woods and out (in the heat of the summer).

A belt that functions as a narrow pack, this hydration device is nice and streamlined. It also places your water bottle at a relatively convenient waist level, for easy grabs and deposits as you trek about. The CamelBak belt comes with a 17-ounce flask for water and is both breathable and comfortable when hooked up. The reflective details are nice for after hours outings and there’s even a secure area for your phone.

Hikers take note: There’s a slick integrated carry function for trekking poles. This baby also packs up really nice for travel too. Consider it a fitness holster that you can wear even on the most arduous of hikes or jogs. It’s great for joggers but just as good for skiers and SUP folks too.

Set up with all kinds of reflective flair, the Summit Series was always a shoo-in for the best option when night falls. Great adjustability means the proper fit even when you’re wearing an extra layer during a chilly evening run. And, given its slim build, it’s all the better for quick outings in the dark, like run club outings with your friends or trail jogs with a good headlamp.

But do wear it during the day too, especially when conditions are hot. The moisture-wicking is actually quite impressive and our editors loved the overall fit. All of the pockets are quite accessible and the pair of bungee sternum straps make for a nice wear, even several miles along. There’s even an ice axe compartment in the back for you mountain-conquering warriors.
