An accessory-only way into a niche that already buys bottle carriers but wants a flat fit that regular slings don't give them.
Executive summary
A flat-bottle sling is a small but real accessory business. You're not trying to compete with bottle brands.
People clearly want bottle carriers and slings. The premium ones sell for about €30-€60, and buyers keep complaining that they're bulky, don't fit right, and hang badly on the body.
The angle here is a standalone accessory made only for flat bottles. That keeps the product simple and means you're not going up against the bottle makers. But it also caps your market at people who already own flat bottles.
The best reason to do this: the product is small, made of fabric, and cheap to ship. The biggest risk: you're betting on a niche format whose popularity you can't control.
- General bottle carriers already sell at €25-€60.
- On Reddit, people are asking for better slings and complaining that the ones they have are too bulky.
- The market is smaller than mainstream bottle accessories, but so is the work of building and shipping it.
