Stay Safe and Organised with the Spinlock Waterproof Bum Bag

When out on the water, whether racing, cruising or enjoying a relaxed day of exploration, there is always one essential requirement: keeping your most important items safe, dry and within easy reach.
That is why we are proud to stock the Spinlock 2 litre 100% waterproof bum bag, a cleverly designed piece of equipment that is fast becoming an indispensable companion for sailors, water-sports enthusiasts and outdoor adventurers. Compact, reliable and built to endure the harshest of environments, this waterproof waist pack offers the reassurance that your essentials will always be secure.
Waterproof Confidence You Can Rely On
For us, the appeal of the Spinlock waterproof bum bag lies not just in its durability but in its practicality. Sailors know how unpredictable conditions can be and the difference between having your equipment to hand and scrambling to find it could be critical. Rated to IPX7, the bum bag is fully waterproof to a depth of one metre, ensuring complete protection even in challenging conditions.
Unlike standard bags that may repel the occasional splash but fail when submerged, this design provides genuine waterproofing, which means you can head out with confidence, knowing that your gear is properly protected.
Safety Features That Inspire Confidence
When venturing out on the water or into the wilderness, safety is always a top priority. The Spinlock waterproof bum bag has been created with this principle at its core. Its bright accents and reflective detailing mean the bag is visible even in low-light conditions, helping to enhance your personal safety.
Additionally, the easy-to-grip waterproof zip has been designed for quick operation, even with cold or gloved hands, ensuring your essential equipment is accessible in an instant. For sailors, kayakers and paddleboarders, this attention to safety detail is particularly reassuring, offering you peace of mind on your adventures.
Compact Yet Practical Design
One of the strengths of this product is its compact yet highly functional design. With a capacity of two litres, it is perfectly sized for carrying essential safety equipment such as a sailing knife or torch, while also accommodating smaller personal items like a phone, a wallet or an energy bar.
Carefully designed with the user’s comfort in mind, the Spinlock waterproof bum bag has Adjustable straps that allow the bag to be worn securely around the waist without restricting the wearer’s movement, which is vital during active sailing manoeuvres or outdoor pursuits.
Unlike bulkier alternatives, this slimline design sits neatly against the body, minimising snagging and ensuring freedom of motion whether you are trimming sails, climbing over deck fittings or hiking through rugged landscapes. Its thoughtful ergonomics make it an accessory you can forget you are wearing until the moment you need it.
Durable Materials for Demanding Environments
Another feature that sets the Spinlock waterproof bum bag apart is the fabric from which it is made. Constructed using PVC-free TRU® waterproof material, it is both eco-friendly and highly durable. Engineered to withstand constant exposure to the elements, it resists salt spray, sunlight and everyday wear without compromising on performance.
The bag also benefits from a self-healing waterproof and dustproof zip closure, which means it can be relied upon for long-term use without fear of leaks or failure. Inside, thoughtful details such as an internal mesh pocket and a lanyard ensure that smaller items remain organised and secure, avoiding the risk of rummaging at critical moments or losing gear overboard.
Beyond Sailing: A Bag for Every Adventure
Although the product is ideal for sailors, it is far from being limited to marine use. We have found that it appeals equally to those who enjoy hiking, paddleboarding, kayaking, fishing or even attending outdoor events where unpredictable weather is a factor. The lightweight design makes it comfortable to wear for long periods, while the waterproofing ensures that your belongings remain completely protected. From keeping a phone dry during a coastal walk to safeguarding valuables on a river trip, its versatility is one of the reasons we recommend it so highly.
