FAQ
Can I use these hydration packs for running?

Do all packs include a water bladder?
Yes. Each pack includes a 2 L or 3 L Gregory reservoir with bite valve and magnetic tube retention. There’s no need to buy a separate hydration system, everything you need comes included, ready for adventure.
Are these suitable as hiking backpacks with water bladder systems?
Absolutely. These hydration packs are popular among hikers because they balance low weight with smart storage and reliable hydration. The Salvo/Sula 16 is especially suited for hiking thanks to its capacity and body-specific fit.
Can I clean or replace the hydration reservoir?

Are these hydration backpacks waterproof?
While not fully waterproof, the packs are highly weather-resistant and made from water-repellent materials. For heavier rain, we recommend pairing with a rain cover to keep your kit dry. Internal sleeves and sealed compartments help protect valuables in wet weather.
