Midnight Black LED Hydration Rave & Festival Bag

Goes with everything. Until you switch it on.

Midnight Black is the one you buy when you don't want the bag to be the outfit. Glossy black, reads as a normal pack in daylight, works with any fit you've already planned — and then the red LED panel comes on and it's suddenly the brightest thing in the room. Red against a gloss black shell is the moodiest combination in the line: less floodlight, more warning light. Three modes (solid, blink, rapid blink), 18+ hours on one set of AAA batteries, and a full 2L hydration pack underneath with a hidden anti-theft pocket sitting flat against your back, plus a chest strap so it stays where you put it.

Why you'll love it

• It matches everything. Glossy black in daylight, so it doesn't fight whatever you're wearing — then lights red after dark.
• It lasts the whole night. 18+ hours per set of 3 AAA batteries, removable so spares are easy.
• It stays put. Adjustable shoulder straps plus a chest strap — no shifting mid-set.
• Your phone doesn't get stolen. Hidden anti-theft pocket against your back, out of reach in a crowd.
• 2 litres of water. 500ml more than the mini line, which counts on a long day.

Midnight Black LED hydration pack specifications

Will it get into your festival?

Each event sets and publishes its own maximum bag size, so check yours before you travel instead of relying on a general answer. The measurement you need: this pack is 15 in (H) x 7 in (W) x 4 in (D).

Our Coachella bag policy guide works through one event's rules in full, and rave vs hiking hydration packs explains why some festivals limit compartment count rather than size.

Taking it to Burning Man?

Black Rock City has no bag policy and no pocket limit, and the official Survival Guide lists “lights for your bike and your person” as required kit — so an LED pack does a job there that a plain pack doesn't. Read the Burning Man hydration guide before you go.

Frequently asked questions

Does it have a chest strap?

Yes. All four LED colorways have a chest strap across the front in addition to the adjustable shoulder straps, which keeps the pack from shifting while you're moving. Note that the Drippy mini packs do not have one — they're shoulder straps only.

What colour do the LEDs glow?

Red. Worth being clear on how this works, because it's the thing people most often get wrong: the colour is fixed and cannot be changed on demand. The three modes change the flash pattern — solid, blink, rapid blink — not the colour. Each colorway ships with its own LED colour: Midnight Black is red, Silver is blue, Hot Pink is white, and Clear Sparkles uses a multi-coloured strip that shows several colours at once. None of them have a colour-select button.

How long do the LEDs last?

18+ hours on a single set of 3 AAA batteries, which covers a full festival night with margin. The batteries are removable rather than sealed in, so for multi-day events you can carry spares and swap them in about ten seconds.

Does it come with batteries?

No. It takes 3 AAA batteries and they aren't included. Standard alkaline AAAs are fine; rechargeables work too.

How much water does it hold?

2 litres, about 68 oz — 500ml more than the mini line. How much you actually need across a day depends on heat, effort and what else you're drinking; more in how much water you need at a festival.

Can I wear it in the rain?

The shell is TPU-protected, the zippers are water-resistant, and the battery pack sits inside a water-resistant pocket rather than exposed. That's built for rain and spilled drinks, not for submerging. We haven't published a formal water-resistance rating because we'd rather test it properly than quote a number we can't stand behind.

How do I clean the hydration bladder?

Remove the bladder, hand-wash it with warm water and mild soap, then hang it open until completely dry before storing. Never a dishwasher or washing machine. The pack is spot-clean only. Full method in how to clean a hydration bladder.

What size person does it fit?

The shoulder straps are fully adjustable and there's a chest strap to fine-tune the fit, so it works across a wide range of body types and layers over a jacket. We haven't published a specific chest-size range yet — we'd rather measure it than estimate.
