Know before you buy
An IPX5 rating means the main compartment is protected against sustained low-pressure water jets, such as heavy rain or splashing. While it is highly weather-resistant and features RF-welded seams, it is not designed to be submerged underwater.
The AirSpeed system uses a tensioned mesh back panel to create a gap between your back and the pack. This promotes significant airflow to keep you cool and helps distribute weight evenly across your hips and shoulders for better stability.
Yes, the Downburst 36 features an external hydration reservoir sleeve with a center pass-through port, allowing you to easily route your hose without opening the main waterproof compartment.
The roll-top closure is designed to ensure a watertight seal for the main compartment. While it requires a few extra seconds to open and close compared to a standard zipper, it provides superior protection against the elements.
The front pocket is designed to hold bulky or wet items that you want to keep separate from your dry gear inside the main compartment. It is perfect for storing a rain shell, extra layers, or gear you need to grab quickly.
No, the Downburst 36 is not carry-on approved. Its dimensions exceed the standard carry-on size limits for most major airlines, so it is best suited for outdoor use rather than air travel.
