For the past few years, I have thrived on the simplicity and ease of sling bags and belt bags, but even I have to admit they have one critical flaw: They make it impossible to carry my water bottle around. The solution? A water bottle sling.
Our top picks for the best water bottle slings of 2024:
Most sling and belt bags are small by definition, which means you're lucky if you can fit your wallet, phone, and sunglasses inside, let alone a whole hydration device. And even if you manage to stuff a water bottle in there, you risk it leaking or spilling everywhere. TL;DR: If you are serious about hydration, you need a water bottle sling. How do I know? Well, I tested some myself, polled Cosmo editors for their expert recs, and combed through reviews to find the best water bottle sling bags and bring them straight to you.
Specifically designed to hold a water bottle and keep it upright and secure, these water bottle sling bags will keep you hydrated all day long without the need to lug around a big tote bag or backpack. You can thank me later.
Pros
- Drawstring closure helps keep your water bottle secure
Cons
- No card slots, so your personal items can get disorganized
The Calpak water bottle holder is well-loved among Cosmopolitan editors. Cosmo Beauty Editor Beth Gillette has one, as does Associate Shopping Editor Megan Uy, who calls the Calpak water bottle holder "a game-changer." She loves that it fits her "BAWB (Big Ass Water Bottle)" and all of her necessities. "It's lightweight, has adjustable straps, and isn't bulky whatsoever," she says. "Because of that, I've never had to choose between being dehydrated or bringing along my reusable water container."
- Water bottle capacity: up to 32 oz (without handle)
- Pockets: 4
- Dimensions: 4 x 4 x 9.5"
- Straps: Top carry handles, adjustable crossbody strap
- Colors: 16
Glowing Customer Review: "This is one of my favorite CALPAK items. I love it because it has so many pockets on the outside where my phone fits my keys, fit sunscreen, my chapstick and all of my little things that I don't wanna have in my hands. I love how they fit there with my water bottles, which are pretty big.
Pros
- Comes in tons of colors and finishes
Cons
- Some reviewers don't like the wide strap
The WanderFull HydroBag was one of Oprah's Favorite Things of 2023, and for good reason. The nylon bag is weatherproof, big enough to fit a 32 oz water bottle, has a zipper pocket for essentials, and has a wide strap (which will come in handy if you want to lug around a bottle of water all day and not end up with a seriously sore neck). The best part, though, is that it comes in 31 different colors and finishes, and each has a different complimentary strap.
- Water bottle capacity: Up to 32 oz (3.5" in diameter)
- Pockets: 2
- Dimensions: 4.75 x 4.75 x 11"
- Straps:Adjustable crossbody
- Colors: 31
Glowing Customer Review: "I love this purse. I've bought 4 different water bottle holders, and this one is amazing. It's been to Spain, music festivals, Utah, hiking, and it's been my everyday purse since I bought it two months ago. It still looks great. Tonight, I figured out it can hold a wine bottle! It's awesome."
Pros
- Very lightweight and small
Cons
- Doesn't fit much else other than a water bottle and your phone
I'm a huge Béis fan, so when I saw this water bottle sling, I knew I had to have it. It fits a regular-sized, 20 oz water bottle in the main compartment, which features a drawstring closure to keep your bottle secure, and has a zip pocket for keys, cards, and your phone. It's small, but mighty, and the perfect companion for short walks around the neighborhood or days at the beach.
- Water bottle capacity: 20 oz
- Pockets: 2
- Dimensions: 3.5 x 3.5 x 8.25"
- Straps: Side carry strap, adjustable crossbody
- Colors: Beige, black
Glowing Customer Review: "This bag is my go-to any time I leave the house. If I'm bring water, obviously, it's great for that and the front pocket is big enough for my phone, cards, keys, and lip balm. I still use it without a water bottle and just use the adjustable pocket for other storage. Very comfortable, even when wearing all day walking around."
Pros
- Drawstring closures on 3 main outside pockets keeps belongings secure
Cons
- Can be hard to remove belongings from main pocket without taking out the water bottle
Dagne Dover is known for its neoprene fabric, which feels substantial without looking bulky—aka, exactly what you want in a water bottle bag. This one is pricey, but the features—two drawstring side pockets, a place for your phone, and a small zip pouch at the back—and elegant design are worth it. It's also equipped with an interior mesh pouch for cards, lip gloss, etc, and a key leash, so you won't have to dig around your water bottle to find your keys.
- Water bottle capacity: up to 32 oz
- Pockets: 5
- Dimensions: 6.5 x 5.25 x 7"

Pros
- Comes with a basic water bottle
Cons
- The water bottle pocket isn't secure enough for extreme activities
This CamelBak sling is made to accompany you on any outdoor adventure and make sure you stay hydrated along the way. The pack features a large zipper-close compartment, which many reviewers say can hold all their hiking essentials and more (including an extra layer in case of wind chill or rain), and a large, elastic pocket in front for easy access to your water bottle. And if you're going on a long trip and feel like you need to bring some extra H2O, the pack is also compatible with CamelBak's 1.5L water bladders.
- Water bottle capacity: 20 oz
- Pockets: 2
- Dimensions: 5.91 x 8.27 x 14.96"

Glowing Customer Review: "I use this bag when I ride my eBike, which is super compact and has no storage space whatsoever...so it comes in handy to keep things like my bike chain, keys, Airpods case, etc. It has a good amount of storage considering it is very small. I've also used it to keep small items that I might run to the store and get while on the bike and it handles that well. I even put a whole bottle of wine in it (hey, don't judge)."
Pros
- Features shoulder padding on the crossbody strap
Cons
- Not available in solid colors
Water bottle sling bags are not one-size-fits-all. At least, not if you prioritize a super snug fit. This water bottle sling comes in four different sizes, so you can comfortably (and securely) carry whatever bottle you want. I like this one because it comes in cute patterns and has two zipper pockets for added storage.
- Water bottle capacity: 25, 32, 40, 64 (4 separate sizes available)
- Pockets: 3
- Dimensions: 3.23 x 3.82 x 9.05"
- Straps: Adjustable crossbody, carrying handle, small side strap
- Colors: 21
Glowing Customer Review: "This is a great water bottle carrier. I walk daily and it is wonderful, keeps my phone and water bottle cool on this hot, smoldering summer. It's not bulky, but the perfect size and lightweight."
Pros
- Adjustable strap offers extra security to keep your water bottle in place
Cons
- It's a bit on the bulky side
Looking for a water bottle sling with a little more storage? In addition to having space for your water bottle, this option from Corkcicle has a roomy main compartment that can comfortably fit your keys, wallet, phone, and even sunglasses. It's definitely the kind of water bottle sling you could use as an everyday purse, even if you accidentally forget your water bottle at home.
- Water bottle capacity: Up to 40 oz
- Pockets: 2
- Dimensions: 4.75 x 5.5 x 9.75"
- Straps: Adjustable crossbody
- Colors: 11
Glowing Customer Reviews: "I purchased this bag in the summer of 2021 and 3 years later, it's still my most functional bag! I never leave the house without a water bottle and this sling made it SO easy and comfortable to carry my beverage along with sunglasses, wallet, etc in the zippered pouch.
Pros
- Zip pocket includes 3 card slots
Cons
- One reviewer notes the inner snap closure scratched their water bottles
It's no secret that I love my bags as bright as possible. If you can't have a fun, colorful accessory, what's the point? This water bottle sling from Swig Life comes in a handful of bright, colorful patterns and styles. But that's not the only reason it's on the list. The neoprene bag is also super durable and has a medium-sized zip pocket to carry any other odds and ends. Plus, the main compartment also features a snap button, so you can close it if you decide to use it as your daily purse.
- Water bottle capacity: up to 36 oz (up to 3.5" diameter)
- Pockets: 2
- Dimensions: 5 x 4.5 x 8"
- Straps: Adjustable crossbody strap
- Colors: 11
Glowing Customer Review: "This bottle carrier is so convenient for hands free carrying! And my phone actually fits in the zippered pouch! A huge plus for me since I have a big phone (Samsung s24 Ultra). Most pouches designed to use for cellphones are too small for mine, but it fits perfectly in this one—with room to spare."
