I don’t go anywhere without my water bottle or coffee thermos, but I’ll admit these reusable vessels can be a real pain to transport. They’re heavy to carry when full and even when empty demand the service of an entire hand. This lack of hands-free movement quickly becomes annoying during anything from errand runs to sightseeing and walks — and, I’ve found, makes it more likely you’ll eventually lose your thermos since you’ll inevitably have to put it down.

When I came across this bestselling water bottle holder from CalPak, I immediately felt that I had found something special — and a solution to my problem.

It had all the features I could’ve wanted. An expandable, insulated pocket for bottles and thermoses, which could even hold my large 40-ounce bottle. Four external pockets, one of them zippered, for storing everything I’d possibly need while out: Keys, wallet, my smartphone, earbuds, sunglasses, lip balm, lipstick and travel SPF. An adjustable, detachable shoulder strap for crossbody and over-shoulder wear, plus a duo top handle for the option of hand-carrying.

The CalPak water bottle holder has four external pockets, two strap options and an insulated inner liner.

Made of water-resistant nylon, it felt high-quality, able to withstand the knocking around that I inevitably subject my possessions to, especially carriers and bags. While the price was a little steep, the water bottle holder’s cost shone through in its material and features — this is clearly worth the money it costs, for those seeking easier on-the-go hydration and organization. “It’s like having eight hands,” said one reviewer. I concur.

I’ve found it works beautifully for walks around the neighborhood, shopping, errands and day trips while traveling. Reviewers also love using it at the gym to keep their water, keys and other items together in one place. I’ve used it while hiking too, though depending on how much water you carry and how difficult your trek is, it can get a little heavy, which is why I like it best for shorter hands-free jaunts.

Plus, if you do get some spillage, the insulated inner liner will hold everything in so the rest of your belongings won’t get wet. One reviewer named Jeannine recounted a cup spilling inside her CalPak holder on an amusement park ride: “I panicked thinking on the outside pockets my stuff was wet. But no! Everything was dry, the lining in the inside kept my stuff dry on the outside!!” she wrote. “Love it!!!! It’s my go to bag for parks now!!”

The CalPak water bottle holder works great for walks, sightseeing while traveling, errands, shopping and more.

All in all, it’s incredibly handy and simply a nice tool to have on hand for those dedicated to their to-go drinks. “It’s a bag that brings joy,” wrote one reviewer, Allie, echoing the Marie Kondo method’s famous “does it spark joy” sentiment. It’s so useful that you might want to grab multiple in case others in your household start competing for it: “My husband is going to get one for his birthday because he keeps trying to steal mine,” wrote another reviewer named Cat C.

I chose a classic black, but it comes in tons of colors and designs, like a limited edition daisy print, earthy gingham, powder blue, rouge red and many more.

“I expected to like this water bottle holder, but not as much as I actually do. I carry a 32oz water bottle that never fits in cup holders or bags, and this is the perfect sling to bring when I’m going out for a long period of time, hiking or walking. Perfectly fits keys, headphones, phone, sunglasses, chapstick and cards. Going to get more as gifts for friends. It’s a bag that brings joy :)” — Allie

“I love her! I have a 40oz hydroflask that I always take with me. Previously, I have always used a para cord handle off Amazon, which works, but I wanted to try something different. All the different pockets on here is what sold me! Now, I’m a chronic overpacker, and I’m sure I’ll always be, so my day-to-day bag is filled with my wallet, snacks, mini skincare, and firstaid stuff, to name a few. What I like about this is that I can fit my wallet into the small zipper pocket, and fit hand sanitizer, medical grade scissors (these come in handy!!), lotion, sunscreen, chapstick, a pen, and a couple small granola bars in the remaining pockets! And I can clip my reusable bags on here as well on the side clips that secure the large strap. I’ve transitioned to this if I ever have to drop packages off at the post office of go grocery shopping. It’s been a game changer! I have yet to bring this baby on a hike, but I’m looking forward to it!” — Allex L.

“I got this bag for travel one year ago after seeing it on TikTok. Since then it’s gone on multiple international 2+ week trips and has become my favorite bag. It holds everything I need it to: phone, wallet, sunglasses case, keys, hand sanitizer, and a 32 or 40 ounce water bottle, with room to spare! I’ve drank more water than ever having this since it’s always on my hip and I love always having my hands free. Now I will say- I’ve gotten this bag incredibly dirty. Scooter rides through Asia, atv rides, boating, beaches, caught in rainstorms, etc. I use gentle detergent and warm water to clean after trips but it doesn’t go back to brand new. I’m okay with this, just next time I will get a darker color. This will forever be a staple for me!” — M

“Love this bag I thought my 64 oz water bottle wasn’t going to fit but it did!! I can put a small wallet and carry other small things in the pockets!! And I carry it everywhere! Y’all need to get yourselves one of these!!” —  Gabrielle G.

“I bought this to use at the gym while weightlifting. It was so annoying to have to carry my phone, keys, and water between machines. This bag is perfect! Now I don’t have to put a bag in a locker and can just have all my stuff with me. It holds my 32oz Hydroflask perfectly where I can sip the straw while it’s still in the bag. The purple color is so pretty too, and I love that I can wipe it down when I’m done at the gym!” — Kelsey P.
