Why the team loves the Hydration Sling

okay wait… why is the hydro sling actually perfect?? 😭 I brought it to a show last weekend and it was the first time my shoulders didn’t hurt by the end of the night. It’s small but not in a useless way. Water + phone + essentials and that’s it...10/10

This is probably my favorite launch from Lunchbox! It feels like they actually listened to everyone asking for something lighter. I don’t always want a full backpack but I also don’t want to carry a water bottle all night plus they integrated the cloud mesh from their hydration packs to this so its comfortable to wear for extended hours. This solves the problem of having a strap dig into my shoulder!

I'm a loyal lunchbox hydration pack user for festivals, but the hydration sling may be my new go to! I love that it has a hydration system and is compact as a cross body pack with TONS of organization. But perhaps my FAVE thing is that it sits so comfortably on my body. It doesn't slide down when I dance like other packs do and the weight feels evenly distributed. The cloud mesh also prevents any chafing when I wear it on bare skin. It's a 100/10 for me!

The Cloud Mesh padding is so soft it doesn't even feel like I'm wearing a pack. I love the ambidextrous design—I can swap the hose to either shoulder depending on my outfit. Fits my iPhone Pro Max with room to spare!

Frequently asked questions

Will my phone fit in the anti-theft pocket?

Yes! The body-facing anti-theft pocket is designed to fit even the largest smartphones (including iPhone Pro Max and Samsung Ultra models) with a standard case. It sits flush against your back/chest, so you can feel it vibrate but thieves can't reach it.

Can I wear the Hydration Sling on either shoulder?

Absolutely. We designed the Hydration Sling to be ambidextrous. It features dual hose exit ports (one on the left, one on the right) so you can configure the strap and the hydration hose to sit on whichever shoulder is most comfortable for you.

Is the 1.2L bladder included?

Yes! Every Hydration Sling comes with our custom 1.2L Insulated Bladder and a matte black insulated hose. The bladder is designed specifically for the sling's compartment to minimize sloshing and maximize space.

Is this bag "Security Line Approved" ?

Yes. We designed the Hydration Sling specifically to meet the strict hydration pack policies of major festivals (like EDC, Ultra, and Lost Lands). The dimensions (14” x 8”) and clear separation of the bladder compartment make it easy to breeze through security checks.

How does the hose stay in place?

No dangling hoses here. The Hydration Sling features our new "Stealth Strap Slide"—a movable retention clip on the main strap that keeps your hose pinned securely to your chest until you’re ready to drink.

Is the material waterproof?

The bag is highly water-resistant. It is made from coated 420D Diamond Ripstop which sheds water effectively. While it can handle rain, spills, and the rail, it is not fully submersible (so maybe don't go swimming in the ocean with it!).
