7 Reasons Why 500,000+ Women Who Carry a 40oz Everywhere Are Replacing Their Purse With This Bottle Sling That Carries the Phone and Keys Too

The cup was never the problem. I had been juggling it against a purse for years and blaming the cup, when the purse was the thing full of stuff I did not need out of the house.

Then I put the cup in the sling, zipped my phone and cards into the front, and walked out the door. That was the whole realization: everything I actually leave with fits around the cup. The purse was the extra thing.

It went on a closet shelf in early spring, and I have not carried it since.

The park day is the real test. Twelve hours on foot, a four-year-old who wants to be carried by hour nine, and nowhere to set anything down.

The cup rode on my hip the whole day. My phone was up front for the ride photos, our park passes in a side pocket, and when she wanted to be picked up, I did not have to find somewhere to put my drink first.

I did not set the cup down once. I did not look for it once. That alone would have been enough.

I found out the sleeve is insulated by accident, at a football game in September heat, when I went for a sip in the fourth quarter and heard ice.

The cup does the cold, and the insulated sleeve helps it keep drinks cold for hours. I had bought it to carry my water. I had not counted on that part.

Market mornings, the bleachers, the back half of a dog walk in August: cold water when I get to it, not the warm water I used to dump out in the parking lot.

The first thing I checked, because it is the first thing everyone asks: it fits the big handled tumblers, 30 to 40 ounces, handle and all. Mine slides in with the handle outside the sleeve, and the strap carries the weight at my hip.

If your cup is a narrow bottle with no handle, check the fit before you order. The sleeve is cut for the big handled cup, and the big handled cup is what it holds.

Mine has stayed put, on the hip and on the trail.

I ran an experiment. Seven days, no purse, only the sling: the grocery store, the gym, a Saturday market, a dinner out.

Phone in the front zip. Cards and cash in the second zip. Keys on the hook inside. Lip balm and a hair tie in the elastic pockets on the sides. Every single thing I reached for was there, and nothing I did not need was.

On day eight I put the purse back on and took it off in the driveway. That was the end of the experiment.

You know the moment: you set the cup down to pay, to buckle a seat, to sign something, and you are halfway to the car when you remember it. I have lost two good cups that way.

Now the cup stays in its sleeve while I reach for my cards. I pay, I buckle, I sign, and the cup never leaves my hip, because there is no reason to take it off.

Six months in. Zero cups left on a counter, a bleacher, or a cart.

Right now it is Buy One, Get One Free: you choose Buy 1, Get 1 Free on the product page and pick two colors. I picked two for myself and planned to rotate them.

My husband borrowed the black one for a Saturday of errands, cup in, keys on the hook, and that was the last time it hung on the hook by our door. It lives on his shoulder now, and he was the one who called the sling "a lot" when the box arrived.

We each carry our own things now. If you order two, pick a second color you are willing to lose.

Over 500,000 women have ordered from Emmafy, and when I went looking for reviews before ordering, this one described the switch better than any pocket count could:
