Pulse Hydration System

Ditch the bladder. Drink from a bottle you can see. Hydration bladders are dark, hard to dry and grow mold you can't see. The Pulse Hydration System replaces the bladder with an ordinary soda-style water bottle: screw the Pulse cap on, drop the bottle upside down in your pack, and sip through the bite valve. When it's empty, swap in a fresh bottle.

How it works: The Pulse cap threads onto the bottle. A built-in check valve lets air back in so the bottle doesn't collapse, and a 1 m (39 in) tube runs to a 360° silicone bite valve. No assembly, no tools — set up in about 60 seconds.

Which bottles fit: If a soda cap fits it, Pulse fits it. Pulse fits bottles with standard 28 mm single-start soda-style threads, such as Aquafina, smartwater and FIJI. Dasani and Gatorade bottles do not fit. 63 mm wide-mouth bottles such as Nalgene fit with our wide-mouth adapter, sold separately.

For cold drinks. Use Pulse with water and other cold drinks only — not for hot liquids.

Works with most packs. Fits backpacks and hydration packs with a reservoir sleeve or bottle pocket, including CamelBak, Osprey, Gregory and Deuter. Great for hiking, parades, theme parks, strollers and motorcycles.

Easy to clean: no bladder to scrub. Dishwasher-safe parts, all components 100% BPA free.

What's in the box: Pulse cap with built-in check valve, 1 m drinking tube, hose barb connectors and a 360° silicone bite valve. Bottle not included. 63 mm wide-mouth adapter sold separately.

Patent-pending design, made with precision tooling — not a DIY tube adapter.
