This simple travel hack can make sure you stay hydrated during your vacations

A water bottle sling bag keeps hydration close at hand and saves you from carrying a heavy backpack through long, hot travel days.

On my recent holiday, I reached a point where I could not tolerate carrying a bulky backpack all day. I wanted a simple sling bag with a wide strap and just enough room for essentials. The only problem was my water bottle. I drink nearly four litres of water a day. And in hot, humid destinations across Asia, stepping out without one is not an option. After plenty of searching, I found water bottle sling bags, and they are genuinely brilliant. They hold your bottle securely and often include small pockets for cash, hotel key cards and a forex card. This tiny addition made walking 20,000 steps a day in Singapore, on a cruise, and at Universal Studios feel far more comfortable and easy to manage, unlike a bulky backpack.

A compact water bottle sling bag paired with a crossbody makes sightseeing easier, lighter and far more comfortable in warm, humid destinations.

What exactly is a water bottle sling bag?

A water bottle sling bag is a compact carrier designed to hold your bottle securely while keeping your hands free. Most include a shoulder strap and small zip pockets for essentials like cash, cards and keys. It is a practical way to stay hydrated on your holiday without carrying a large bag all day.

How to style these with your regular sling bag for that perfect ease?

• Wear the bottle bag on one side and your sling bag on the other.
• Choose matching colours for a coordinated look.
• Keep valuables in your main bag and quick-access items in the bottle pouch.
• Adjust both straps so they sit comfortably without overlapping.
• Use only the bottle sling for short walks and coffee runs.
