Having safe drinking water on a day hike or paddle shouldn't require carrying extra gear or stopping to pump.

The DayCap screws onto any wide-mouth bottle and turns it into a capable backcountry water filter with almost no change to how you actually drink. The hollow fibre filter inside is the same proven technology found in Platypus's most trusted filtration systems, flowing at up to 1 litre per minute and individually tested to meet EPA and NSF guidelines for removing 99.9999% of bacteria and 99.9% of protozoa, including Giardia, Cryptosporidium, and E. coli. It handles particulates too, making it a solid choice for the silty lakes and streams you'll encounter across Canadian wilderness.

When flow starts to slow, just shake the cap while it's still on your bottle to break up particulates and get things moving again. No tools, no backflush kit required. The filter cartridge also detaches with a half-turn when you want to use the cap on its own, and the semi-flexible carry loop gives you a reliable attachment point on a pack strap or gear loop. The TPE construction feels durable and grips well, holding up to the kind of daily use a proper water filter bottle cap should handle.
