Hydration Secured.

Stay prepared with a rugged paracord bottle leash or sling for the trail and beyond.

Why THIRSTLOCK

Tired of your water bottle launching out of your backpack whenever you bend down, tie your shoe, or suddenly dodge right because your situational awareness is elite and there’s no way you’re letting that poisonous spider land on your neck? Yeah, us too.

That’s why we make THIRSTLOCK™ bottle leashes and slings. They keep your bottle where it belongs: attached.

Bottle Leashes

Our bottle leashes are designed to attach a water bottle to your backpack or other gear using high quality carabiners and a rugged paracord strap.

Bottle Slings

THIRSTLOCK™ paracord bottle slings are minimalist, cross-body slings that let your bottle ride at the hip, like an old-school canteen. All of our slings are custom length builds to provide the best possible fit.

The same cord trusted by adventurers and outdoor professionals can be unraveled for use in emergencies or just when you need to improvise a little in the field.

Secured with Premium Hardware

Nite Ize® locking carabiners offer the perfect balance of strength, weight, and reliability, making them ideal for securing your bottle without unnecessary bulk.

Customize your rig with your choice of SlideLock® Carabiner, or Ahhh...™ bottle opener carabiners.
