Hydration backpack with 2L bladder – festival-ready and lightweight
After a compact, stylish hydration pack that actually does the job? The RillyRellow hydration backpack is aimed at anyone who wants to stay hydrated and look the part — perfect for raves, festivals, gigs, theme-park days or a proper scorcher of a summer walk. It’s featherlight, has an insulated water compartment and comes with a 2 L bladder, so there’s no faffing about with bottles.
Why this pack works for you
The look is festival-friendly without being daft — a holographic, eye-catching finish that still feels useful rather than gimmicky. The 2 L bladder slots into an insulated sleeve to keep drinks cooler for longer, which is a real bonus when the sun’s out. The oversized screw cap makes chucking in ice a doddle and makes cleaning far easier. The bite valve is silicone, has a dust cover and a quick-release connector, so filling and detaching is straightforward.
- Stay hydrated on the move with a leak-resistant bladder and an easy-access drinking tube.
- Two compartments for essentials — phone, wallet, keys and maybe a lightweight jacket or jumper.
- No heavy bulk: at roughly 13 ounces the pack won’t weigh you down during long festival shifts or bike rides.
- Padded back panel allows airflow so your back won’t turn into a sweaty mess.
- Adjustable shoulder and chest straps keep the pack snug and stop it bouncing when you’re on the move or cutting shapes on the dancefloor.
Technical details and fit
Material – durable polyurethane (PU), water resistant and built to last. Included – the hydration backpack and a 2 L water bladder. Weight – about 553 g (around 13 ounces). Fit – adjustable straps suit a wide range of chest sizes, roughly 26″ to 52″ (about 66–132 cm), so it’ll fit most teenagers and adults. The bladder features a leak-resistant connector and an oversized mouth for ice cubes and easier cleaning.
Use cases and common questions
- Raves, festivals and gigs – hands-free hydration while dancing or queuing.
- Hiking and day walks – light, insulated and keeps water handy without needing to stop.
- Biking and running – low profile so it won’t snag, and adjustable straps help reduce bounce.
- Cleaning – the wide cap helps, but using a proper bladder brush is recommended for best hygiene.
- Leak worries – the connector and bite valve are designed to be leak-proof, but it’s sensible to double-check connections before tucking valuables away in the same pocket.
This pack is ideal for anyone after a fuss-free hydration solution with a bit of style. It isn’t built for heavy-duty mountaineering or multi-day treks packed with kit — for that you’ll want a larger rucksack. For festival-goers, commuters, cyclists and day-trippers, though, it’s a neat, well-thought-out choice that keeps things simple so you can get on with enjoying yourself.
If you’re unsure about fit or suitability for a particular activity, check the chest measurements and remember the insulated sleeve keeps drinks colder for longer — very handy in hot weather, less vital in cooler conditions but still useful. No complicated setup and no faff — just fill, strap on and off you go.
