Why Do You Need a Swim Buoy for Open-Water Swimming?

There’s something uniquely powerful about being in the water. Whether you’re exploring coastlines, training in lakes, or taking on long-distance point-to-point swims, open-water swimming offers a sense of freedom unlike any other sport. But with that freedom comes responsibility – and one of the key ways to improve your visibility, safety and confidence is by using a swim buoy.

At Red, we developed the 2-in-1 Reversible Swim Buoy Backpack to make open-water swimming safer, simpler, and more practical. Here’s why every open-water swimmer should consider adding a swim buoy to their swim set-up.

Visibility Saves Lives

One of the biggest risk factors in open-water swimming is simply not being seen.

Even strong swimmers can become difficult to spot in choppy water, low light, or busy environments shared with boats, paddleboards, kayaks, and jet-skis. A brightly coloured swim buoy creates a highly visible marker behind you, helping other water users spot you much earlier and avoid getting too close.

The 2-in-1 Reversible Swim Buoy Backpack uses fluorescent high-vis colours, reflective detailing, and light attachment points to help maximise visibility across a broad range of open-water conditions – whether you’re crossing a lake at sunrise or swimming along the coast at dusk.

Take Your Essentials into the Water

Open-water swimmers often face the same quandary: where do you leave your stuff while you swim?

A swim buoy with dry storage solves that issue by allowing you to take essentials such as keys, a phone and nutrition into the water with you.

The 2-in-1 Reversible Swim Buoy Backpack goes a step further, with a generous c.19L of waterproof storage, meaning you can confidently take more than just the basics. You can even pack a towel, shoes and some dry clothing for adventure swims or point-to-point routes where you won’t get out at the same place you got in.

Swim Buoys Build Confidence

Open-water swimming can feel intimidating, especially if you’re swimming alone, heading into deeper water, or trying unfamiliar routes.

A swim buoy offers reassurance. It acts as a visible marker to others throughout your swim, helping you feel seen – and therefore more confident and relaxed in the water. For newer swimmers, that extra confidence can make a huge difference: helping them enjoy the experience more and progress faster.

Importantly, swim buoys should never be used as a resting aid or lifesaving device. That said, many swimmers feel more comfortable in the knowledge that they do have a little bit of extra buoyancy within arm’s reach.

Perfect for Adventure and Point-to-Point Swims

An ever-increasing number of swimmers are moving beyond simple out-and-back loops and embracing adventure swimming – exploring rivers, coastlines, islands, and longer-distance routes that don’t finish where they started.

That style of swimming often means carrying kit with you, walking to remote swim spots, and finishing miles away from where you started. In that case, traditional swim buoys and separate backpacks are awkward and impractical.

That’s exactly why the 2-in-1 Reversible Swim Buoy Backpack was created.

Developed around real swimmer feedback, it transforms from a comfortable 28L waterproof backpack into a high-vis swim buoy dry bag in seconds. Simply carry your kit to the shore, reverse the bag, inflate the chambers, and get in. Then after your swim, it reverts back into a backpack to carry wet gear home again.

One piece of kit. No extra bags. No unnecessary hassle.

Comfort Matters…

Poorly designed swim buoys can interrupt your stroke, create drag, or constantly kick back against your legs while swimming. Whereas a good tow system should feel secure yet unobtrusive.

The 2-in-1 Reversible Swim Buoy Backpack uses an adjustable tether designed to optimise tow position and reduce kicking interference, while the extra-long waistband comfortably accommodates a wide range of body shapes and sizes. It’s a more inclusive fit than many traditional swim floats, helping swimmers focus on the water instead of constantly adjusting their gear. Plus it’s been carefully designed to tow through the water as efficiently as possible, with minimal drag, so it doesn’t distract from your swim.

Built Tough for Regular Open-Water Use

Open-water swim gear needs to handle rough treatment, rocky shorelines, sandy beaches, repeated inflation, saltwater exposure, and frequent travel.

That’s why the 2-in-1 Reversible Swim Buoy Backpack is constructed from durable PVC-free TPU with welded seams for long-lasting performance. It’s lightweight, flexible, abrasion-resistant, and designed to withstand years of regular use.

By combining backpack and swim buoy into a single dual-purpose design, it also reduces unnecessary kit and material usage, supporting a more streamlined and sustainable approach to adventure swimming.

For Simpler Swim Days

Open-water swimming should feel freeing, not stressful.

A swim buoy is one of the simplest and most effective pieces of safety equipment you can use to improve visibility and build confidence in the water. Whether you’re training, exploring new swim routes, or simply heading out for an evening dip, the right swim buoy dry bag helps you stay safe while making your swim experience smoother and more enjoyable.

The 2-in-1 Reversible Swim Buoy Backpack takes that one step further – combining smart storage, comfort, visibility, and innovative reversible design into one practical solution. Built for real swimmers, real routines, and real adventures.
