Revelate Designs Mag Tank

The magnetic closure is surprisingly strong and designed to stay shut during standard gravel and road riding. However, if you are planning on tackling extremely rough mountain bike trails or technical singletrack, you might experience some movement since it lacks the mechanical lock of a zipper.

The Mag Tank features a tapered profile specifically engineered to minimize leg rub. Most riders find that it stays well out of the way, though fit can vary slightly depending on your bike's geometry and your pedaling stance.

It is not fully waterproof. While the fabric is durable and weather-resistant, the magnetic closure system is designed for quick access rather than a hermetic seal. It will protect your gear from light splashes and dust, but it is not intended for heavy downpours or submersion.

Yes, that is the primary design advantage of this bag. The magnetic system allows you to flip the lid open and closed with a single hand, making it ideal for grabbing snacks or your phone without needing to stop or fumble with zippers.

The Mag Tank mounts to your top tube and stem area using adjustable straps. It is designed to be compatible with most standard bicycle frames, but ensure you have enough clearance on your top tube to accommodate the bag's footprint.
